Overview

My iOS app “TaskCal: Task Manager” (version 1.2.8) has been stuck in “Waiting for Review” for more than 3 weeks, and I’m not sure what else I can do at this point. I’d like to know if there’s anything wrong with my submission, or if there’s any other way to get more clarity from App Review. Here are the key dates (GMT+8): Jan 30, 2026 – Version 1.2.3 was approved and marked “Ready for Distribution”. Jan 31 – Feb 8, 2026 – I submitted version 1.2.8 multiple times. Several submissions were later marked as “Removed” in App Store Connect. Feb 9, 2026, 12:39 AM – I submitted version 1.2.8 again. This submission has been in “Waiting for Review” ever since. Today is Mar 3, 2026 (Taipei time) – The status is still “Waiting for Review” with no change. Because of this, I contacted Apple Developer Support multiple times through Contact Support. I only received one reply, on Feb 21, 2026, which said: Hello Alan, Thank you for reaching out to Developer Support about your app, “TaskCal: Task Manager.” I understand that you’re concerned. After reviewing your app’s submission history, I can confirm that your app is still in the “Waiting for Review” status as of February 8th 2026. To address your concern about the duration of the review, I’ve contacted the review team to bring this to their attention. At this time, there’s no further action required from your end. If the review team needs any additional information to complete the review, they’ll reach out to you directly. We appreciate your patience during this process. Your case number is 20000107493507. Stephanie Developer Support Since then, there has been no visible progress and no follow‑up messages. The App Review page still shows: Version: iOS 1.2.8 Status: Waiting for Review Case ID: 20000107493507 I completely understand that review times can vary, but: My previous version (1.2.3) was reviewed and approved normally. This is a relatively small productivity app with no major policy changes. It’s been over 3 weeks in “Waiting for Review” for this specific submission, with multiple earlier submissions of the same version being “Removed” without clear explanation in the UI. My questions: Is there anything I may have done wrong in the submission process (for example, causing multiple “Removed” submissions) that could block or delay this review? Is there any other official channel I can use to get more clarity beyond contacting Developer Support (which only confirmed that it’s “Waiting for Review”)? Has anyone here experienced a similar long “Waiting for Review” state recently, and if so, how was it resolved? I’m worried that there might be some issue with this build or with my account that I’m not seeing in App Store Connect. At the same time, I don’t want to keep canceling and re‑submitting if that could make the situation worse. Any advice from Apple or other developers who have gone through something similar would be greatly appreciated. Thank you, Alan

Looking for any guidance on how to duplicate the Display Settings under "Display & Brightness" more specifically the Display Zoom.

It seems like every time an IOS update is installed, the camera app file formats get reset to defaults. This setting is not available to manage at the MDM level. Many people need the the most compatible settings for the purpose of file sharing. So, now we have nearly 1,000 devices with a complete mix of photo and video formats. And IT has wasted MANY hours converting files for people. Feature Request: Please either stop resetting the camera app file formats or allow us to manage those settings at the MDM level. Respectfully, Robert

When I create an archive file and attempt to upload the app using the "Distribute App" button, the upload fails with the error "Automatic signing cannot update bundle identifier...". (The detailed message is below.) When creating an archive file in Xcode, I unchecked "Automatically Manage Signing" and proceeded with the archive. The message says "Font Enumeration," but other apps with the same option enabled upload successfully. Therefore, I believe the "Font Enumeration" option is not the issue. I tried creating a new provisioning file, but it still doesn't work. I deleted all DerivedData files from my Mac storage, restarted Xcode, and tried again, but it still doesn't work. This keeps happening only for certain targets (specific apps) in Xcode. Does anyone know how to fix this? Xcode is the latest version. Message: Automatic signing cannot update bundle identifier "com.xxxxxx.xxxxxx". Automatic signing cannot update your registered bundle identifier to enable Font Enumeration. Update your bundle identifier on https://developer.apple.com/account and then try again.

Hey team, I am reaching out about an app I submitted for review (app id: 6748933312). I started the review process Feb 4th, 26 days ago. The process started off positively - I got my first response within 3 days and had to go back and forth a couple times to bake in some review feedback, which was expected since this was the first submission. I even jumped on a call with Bill who gave some super helpful clarifying guidance! Thanks Bill :) But it then went downhill from there... I submitted my 3rd version on Feb 12th and was hoping that would get me the approval. But then I didn't hear anything for 10 days despite calls to support and a request for expedited review. At which point I wasn't sure what to do and I wanted to iron out some bugs, so i pulled and resubmitted on Feb 22nd, and I still haven't heard back from the team. Stuck in "Waiting for review" for another 10 days. I really don't know what to do now, I can't tell if Apple has just stopped accepting new apps altogether? My friends are able to submit updates to existing apps and get approvals within hours. Pls help, I'm losing hope as a new app developer. -James

I have a submission that required to be release asap since it's a showstopper for users at the moment. Can I please request for the app to be reviewed soon ? I sent an expedite request 2 hours ago. Submission ID 4d687ac2-a4a2-494d-a635-b3845adf86bc

When doing some exploratory research into using Apple Intelligence in our aviation-focused application, I noticed that there were several times that key phases would be marked as inappropriate. I tried to stifle these using prompts and rules but couldn't get it to take hold. I was encouraged by an Apple employee to go ahead and post this so that the AI team can use the feedback. There were several terms that triggered this warning, but the two that were most prominent were: 'Tailwind' 'JFK' or 'KJFK' (NY airport ICAO/IATA codes)

I am writing a DriverKit driver for the first that uses the USBSerialDriverKit. The driver its purpose is to expose the device as serial interface (/dev/cu.tetra-pei0 or something like this). My problem: I don't see any logs from that driver in the console and I tried like 40 different approaches and checked everything. The last message I see is that the driver get successfully added to the system it is in the list of active and enabled system driver extensions but when I plug the device in none of my logs appear and it doesn't show up in ioreg. So without my driver the target device looks like this: +-o TETRA PEI interface@02120000 <class IOUSBHostDevice, id 0x10000297d, registered, matched, active, busy 0 (13 ms), retain 30> | { | "sessionID" = 268696051410 | "USBSpeed" = 3 | "UsbLinkSpeed" = 480000000 | "idProduct" = 36886 | "iManufacturer" = 1 | "bDeviceClass" = 0 | "IOPowerManagement" = {"PowerOverrideOn"=Yes,"DevicePowerState"=2,"CurrentPowerState"=2,"CapabilityFlags"=32768,"MaxPowerState"=2,"DriverPowerState"=0} | "bcdDevice" = 9238 | "bMaxPacketSize0" = 64 | "iProduct" = 2 | "iSerialNumber" = 0 | "bNumConfigurations" = 1 | "UsbDeviceSignature" = <ad0c16901624000000ff0000> | "USB Product Name" = "TETRA PEI interface" | "locationID" = 34734080 | "bDeviceSubClass" = 0 | "bcdUSB" = 512 | "USB Address" = 6 | "kUSBCurrentConfiguration" = 1 | "IOCFPlugInTypes" = {"9dc7b780-9ec0-11d4-a54f-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | "UsbPowerSinkAllocation" = 500 | "bDeviceProtocol" = 0 | "USBPortType" = 0 | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | "USB Vendor Name" = "Motorola Solutions, Inc." | "Device Speed" = 2 | "idVendor" = 3245 | "kUSBProductString" = "TETRA PEI interface" | "kUSBAddress" = 6 | "kUSBVendorString" = "Motorola Solutions, Inc." | } | +-o AppleUSBHostCompositeDevice <class AppleUSBHostCompositeDevice, id 0x100002982, !registered, !matched, active, busy 0, retain 5> | { | "IOProbeScore" = 50000 | "CFBundleIdentifier" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "IOProviderClass" = "IOUSBHostDevice" | "IOClass" = "AppleUSBHostCompositeDevice" | "IOPersonalityPublisher" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "bDeviceSubClass" = 0 | "CFBundleIdentifierKernel" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "IOMatchedAtBoot" = Yes | "IOMatchCategory" = "IODefaultMatchCategory" | "IOPrimaryDriverTerminateOptions" = Yes | "bDeviceClass" = 0 | } | +-o lghub_agent <class AppleUSBHostDeviceUserClient, id 0x100002983, !registered, !matched, active, busy 0, retain 7> | { | "IOUserClientCreator" = "pid 1438, lghub_agent" | "IOUserClientDefaultLocking" = Yes | } | +-o IOUSBHostInterface@0 <class IOUSBHostInterface, id 0x100002986, registered, matched, active, busy 0 (5 ms), retain 9> | | { | | "USBPortType" = 0 | | "IOCFPlugInTypes" = {"2d9786c6-9ef3-11d4-ad51-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | | "USB Vendor Name" = "Motorola Solutions, Inc." | | "bcdDevice" = 9238 | | "USBSpeed" = 3 | | "idProduct" = 36886 | | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | | "bInterfaceSubClass" = 0 | | "bConfigurationValue" = 1 | | "locationID" = 34734080 | | "USB Product Name" = "TETRA PEI interface" | | "bInterfaceProtocol" = 0 | | "iInterface" = 0 | | "bAlternateSetting" = 0 | | "idVendor" = 3245 | | "bInterfaceNumber" = 0 | | "bInterfaceClass" = 255 | | "bNumEndpoints" = 2 | | } | | | +-o lghub_agent <class AppleUSBHostInterfaceUserClient, id 0x100002988, !registered, !matched, active, busy 0, retain 6> | { | "UsbUserClientBufferStatistics" = {"IOMemoryDescriptor"=0,"IOBufferMemoryDescriptor"=0,"IOSubMemoryDescriptor"=0} | "IOUserClientCreator" = "pid 1438, lghub_agent" | "UsbUserClientBufferAllocations" = {"Bytes"=0,"Descriptors"=0} | "IOUserClientDefaultLocking" = Yes | } | +-o IOUSBHostInterface@1 <class IOUSBHostInterface, id 0x100002987, registered, matched, active, busy 0 (5 ms), retain 9> | { | "USBPortType" = 0 | "IOCFPlugInTypes" = {"2d9786c6-9ef3-11d4-ad51-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | "USB Vendor Name" = "Motorola Solutions, Inc." | "bcdDevice" = 9238 | "USBSpeed" = 3 | "idProduct" = 36886 | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | "bInterfaceSubClass" = 0 | "bConfigurationValue" = 1 | "locationID" = 34734080 | "USB Product Name" = "TETRA PEI interface" | "bInterfaceProtocol" = 0 | "iInterface" = 0 | "bAlternateSetting" = 0 | "idVendor" = 3245 | "bInterfaceNumber" = 1 | "bInterfaceClass" = 255 | "bNumEndpoints" = 2 | } | +-o lghub_agent <class AppleUSBHostInterfaceUserClient, id 0x10000298a, !registered, !matched, active, busy 0, retain 6> { "UsbUserClientBufferStatistics" = {"IOMemoryDescriptor"=0,"IOBufferMemoryDescriptor"=0,"IOSubMemoryDescriptor"=0} "IOUserClientCreator" = "pid 1438, lghub_agent" "UsbUserClientBufferAllocations" = {"Bytes"=0,"Descriptors"=0} "IOUserClientDefaultLocking" = Yes } more details in my comment.

Hello, I am reaching out regarding my latest update, which has remained in “Waiting for Review” status for an extended period. In the past, my updates have generally proceeded through review without significant delays, and I would normally be willing to wait if this were part of a broader backlog. However, based on recent experiences shared by fellow developers, it appears that this delay may not be affecting all accounts equally. For this reason, I would like to confirm whether there might be any specific issue with my submission. I have already submitted an expedited review request and contacted Developer Support, but I have not yet received any response. At this point, I would greatly appreciate confirmation on the following: Whether there are any issues blocking the review of this submission Whether any additional information is required from my side Or whether the app is simply still pending reviewer assignment I fully understand that the App Review team may be handling a high volume of submissions. If possible, I would sincerely appreciate it if someone could kindly take a look at my case. Thank you very much for your time and assistance.

Hello, I am trying to upload a watchOS standalone app to App Store Connect using Xcode 26.3, but Organizer does not show the “App Store Connect” upload option. It only displays: • Release Testing (Ad Hoc) • Enterprise • Debugging Project setup • Target type: watchOS App (standalone, not companion) • PRODUCT_TYPE = com.apple.product-type.application • PRODUCT_BUNDLE_PACKAGE_TYPE = APPL • WRAPPER_EXTENSION = app • SUPPORTED_PLATFORMS = watchos watchsimulator • Archive configuration: Release • Base SDK: watchOS The app does not depend on iOS. Bundle ID Originally: com.example.app.watchkitapp Recreated as: com.example.app HealthKit capability enabled in: • Developer Portal • Xcode (Signing & Capabilities) Signing • Apple Distribution certificate active • App Store provisioning profile created • Manual signing configured for Release (Apple Distribution + App Store profile) • Also tested Automatic signing • Deleted old Ad Hoc profiles • Cleared Derived Data and regenerated archive App Store Connect • App created successfully using bundle ID com.example.app • Account role: Account Holder • No pending Agreements, Tax, or Banking items Despite a valid Release archive signed with Apple Distribution, Organizer only allows Ad Hoc distribution and never shows “App Store Connect”. Is this a known issue in Xcode 26 affecting independent watchOS apps, or is there an additional configuration step required? Thank you.

Since macOS 26.4 Beta 1, virtual HID devices created via DriverKit can no longer intercept key events from the built-in MacBook keyboard. External keyboards still work. This is confirmed and tracked here: https://github.com/pqrs-org/Karabiner-Elements/issues/4402 One possible lead (from LLM-assisted analysis of Apple's open-source IOHIDFamily code and cross-referencing community reports): macOS 26.4 Beta may have introduced or modified a security policy referred to as com.apple.iohid.protectedDeviceAccess, which could block IOHIDDeviceOpen for the Apple Internal Keyboard connected via SPI transport (AppleHIDTransportHIDDevice). This appears related to a "GamePolicy" check in IOHIDDeviceClass.m that gates whether processes can open HID devices. This has not been independently verified and may or may not be the root cause. This has far-reaching consequences. Karabiner-Elements alone has over 21,000 GitHub stars and is used by hundreds of thousands of macOS users for keyboard customization, accessibility workflows, ergonomic setups, and multilingual input. This change completely breaks its core functionality on any MacBook. Beyond Karabiner, this affects every developer building keyboard remapping, input customization, or accessibility tooling via DriverKit virtual HID devices — including commercial applications currently in development. I'd argue that the power and flexibility of keyboard customization on macOS is a genuine competitive advantage for the platform. Developers and power users choose Macs partly because tools like this exist. Restricting this capability would be detrimental to the ecosystem and to Apple's appeal among professional users. I'd like to understand: is this an intentional security change or a regression? If intentional, is there a migration path?

I’m encountering a strange, sporadic error in FileManager.replaceItemAt(_:withItemAt:) when trying to update files that happen to be stored in cloud containers such as iCloud Drive or Dropbox. Here’s my setup: I have an NSDocument-based app which uses a zip file format (although the error can be reproduced using any kind of file). In my NSDocument.writeToURL: implementation, I do the following: Create a temp folder using FileManager.url(for: .itemReplacementDirectory, in: .userDomainMask, appropriateFor: fileURL, create: true). Copy the original zip file into the temp directory. Update the zip file in the temp directory. Move the updated zip file into place by moving it from the temp directory to the original location using FileManager.replaceItemAt(_:withItemAt:). This all works perfectly - most of the time. However, very occasionally I receive a save error caused by replaceItemAt(_withItemAt:) failing. Saving can work fine for hundreds of times, but then, once in a while, I’ll receive an “operation not permitted” error in replaceItemAt. I have narrowed the issue down and found that it only occurs when the original file is in a cloud container - when FileManager.isUbiquitousItem(at:) returns true for the original fileURL I am trying to replace. (e.g. Because the user has placed the file in iCloud Drive.) Although strangely, the permissions issue seems to be with the temp file rather than with the original (if I try copying or deleting the temp file after this error occurs, I’m not allowed; I am allowed to delete the original though - not that I’d want to of course). Here’s an example of the error thrown by replaceItemAt: Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “test-file.txt” in the folder “Dropbox”." UserInfo={NSFileBackupItemLeftBehindLocationKey=file:///var/folders/mt/0snrr8fx7270rm0b14ll5k500000gn/T/TemporaryItems/NSIRD_TempFolderBug_y3UvzP/test-file.txt, NSFileOriginalItemLocationKey=file:///var/folders/mt/0snrr8fx7270rm0b14ll5k500000gn/T/TemporaryItems/NSIRD_TempFolderBug_y3UvzP/test-file.txt, NSURL=file:///Users/username/Library/CloudStorage/Dropbox/test-file.txt, NSFileNewItemLocationKey=file:///Users/username/Library/CloudStorage/Dropbox/test-file.txt, NSUnderlyingError=0xb1e22ff90 {Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “test-file.txt” in the folder “NSIRD_TempFolderBug_y3UvzP”."

"Dummy text".write(to: tempURL, atomically: false, encoding: .utf8)) != nil else { return } do { // Use replaceItemAt to safely move the new file into place. _ = try fileManager.replaceItemAt(savingURL, withItemAt: tempURL) print("save succeeded!") try? fileManager.removeItem(at: replacementDirURL) // Clean up. } catch { print("save failed with error: \(error)") // Note: if we try to remove replaceDirURL here or do anything with tempURL we will be refused permission. NSAlert(error: error).runModal() } } If you run this code and set savingURL to a location in a non-cloud container such as your ~/Documents directory, it will run forever, resaving the file over and over again without any problems. But if you run the code and set savingURL to a location in a cloud container, such as in an iCloud Drive folder, it will work fine for a while, but after a few minutes - after maybe 100 saves, maybe 500 - it will throw a permissions error in replaceItemAt. (Note that my real app has all the save code wrapped in file coordination via NSDocument methods, so I don’t believe file coordination to be the problem.) What am I doing wrong here? How do I avoid this error? Thanks in advance for any suggestions.

This is my first driver and I have had the devil of a time trying to find any information to help me with this. I beg help with this, since I cannot find any tutorials that will get me over this problem. I am attempting to write a bridging driver for an older UPS that only communicates via RPC-over-USB rather than the HID Power Device class the OS requires. I have written the basic framework for the driver (details below) and am calling OSSystemExtensionRequest.submitRequest with a request object created by OSSystemExtensionRequest.activationRequest, but the didFailWithError callback is called with OSSystemExtensionErrorDomain of a value of 9, which appears to be a general failure to activate the driver. I can find no other information on how to address this issue, but I presume the issue is one of entitlements in either the entitlements file or Info.plist. I will have more code-based details below. For testing context, I am testing this on a 2021 iMac (M1) running Sequoia 15.7, and this iMac is on MDM, specifically Jamf. I have disabled SIP and set systemextensionsctl developer on, per the instructions here, and I have compiled and am attempting to debug the app using xcode 26.2. The driver itself targets DriverKit 25, as 26 does not appear to be available in xcode despite hints on google that it's out. For the software, I have a two-target structure in my xcode project, the main Manager app, which is a swift-ui app that both handles installation/activation of the driver and (if that finally manages to work) handles communication from the driver via its UserClient, and the driver which compiles as a dext. Both apps compile and use automated signing attached to our Apple Development team. I won't delve into the Manager app much, as it runs even though activation fails, except to include its entitlements file in case it proves relevant <dict> <key>com.apple.developer.driverkit.communicates-with-drivers</key> <true/> <key>com.apple.developer.system-extension.install</key> <true/> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.files.user-selected.read-only</key> <true/> </dict> and the relevant activation code: func request(_ request: OSSystemExtensionRequest, didFailWithError error: any Error) { // handling the error, which is always code value 9 } func activateDriver() { let request = OSSystemExtensionRequest.activationRequest(forExtensionWithIdentifier: "com.mycompany.driver.bundle.identifier", queue: .main) request.delegate = self OSSystemExtensionManager.shared.submitRequest(request) //... } And finally the Manager app has the following capabilities requested for its matching identifier in our Apple Developer Account: DriverKit Communicates with Drivers System Extension On the Driver side, I have two major pieces, the main driver class MyDriver, and UserClient class, StatusUserClient. MyDriver derives from IDriverKit/IOService.iig but (in case this is somehow important) does not have the same name as the project/target name MyBatteryDriver. StatusUserClient derives from DriverKit/IOUserClient.iig. I have os_log(OS_LOG_DEFAULT, "trace messages") code in every method of both classes, including the initializers and Start implementations, and the log entries never seem to show up in Console, so I presume that means the OS never tried to load the driver. Unless I'm looking in the wrong place? Because I don't think the driver code is the current issue, I won't go into it unless it becomes necessary. As I mentioned above, I think this is a code signing / entitlements issue, but I don't know how to resolve it. In our Apple Developer account, the Driver's matching identifier has the following capabilities requested: DriverKit (development) DriverKit Allow Any UserClient (development) DriverKit Family HID Device (development) -- NOTE: this is planned for future use, but not yet implemented by my driver code. Could that be part of the problem? DriverKit Transport HID (development) DriverKit USB Transport (development) DriverKit USB Transport - VendorID -- submitted, no response from Apple yet HID Virtual Device -- submitted, no response from Apple. yet. This is vestigial from an early plan to build the bridge via shared memory funneling to a virtual HID device. I think I've found a way to do it with one Service, but... not sure yet. Still, that's a problem for tomorrow. Apparently I've gone over the 7000 character maximum so I will add my entitlements and info.plist contents in a reply.

Note: This document is specifically focused on what happens after a DEXT has passed its initial code-signing checks. Code-signing issues are dealt with in other posts. Preliminary Guidance: Using and understanding DriverKit basically requires understanding IOKit, something which isn't entirely clear in our documentation. The good news here is that IOKit actually does have fairly good "foundational" documentation in the documentation archive. Here are a few of the documents I'd take a look at: IOKit Fundamentals IOKit Device Driver Design Guidelines Accessing Hardware From Applications Special mention to QA1075: "Making sense of IOKit error codes",, which I happened to notice today and which documents the IOReturn error format (which is a bit weird on first review). Those documents do not cover the full DEXT loading process, but they are the foundation of how all of this actually works. Understanding the IOKitPersonalities Dictionary The first thing to understand here is that the "IOKitPersonalities" is called that because it is in fact a fully valid "IOKitPersonalities" dictionary. That is, what the system actually uses that dictionary "for" is: Perform a standard IOKit match and load cycle in the kernel. The final driver in the kernel then uses the DEXT-specific data to launch and run your DEXT process outside the kernel. So, working through the critical keys in that dictionary: "IOProviderClass"-> This is the in-kernel class that your in-kernel driver loads "on top" of. The IOKit documentation and naming convention uses the term "Nub", but the naming convention is not consistent enough that it applies to all cases. "IOClass"-> This is the in-kernel class that your driver loads on top of. This is where things can become a bit confused, as some families work by: Routing all activity through the provider reference so that the DEXT-specific class does not matter (PCIDriverKit). Having the DEXT subclass a specific subclass which corresponds to a specific kernel driver (SCSIPeripheralsDriverKit). This distinction is described in the documentation, but it's easy to overlook if you don't understand what's going on. However, compare PCIDriverKit: "When the system loads your custom PCI driver, it passes an IOPCIDevice object as the provider to your driver. Use that object to read and write the configuration and memory of your PCI hardware." Versus SCSIPeripheralsDriverKit: Develop your driver by subclassing IOUserSCSIPeripheralDeviceType00 or IOUserSCSIPeripheralDeviceType05, depending on whether your device works with SCSI Block Commands (SBC) or SCSI Multimedia Commands (SMC), respectively. In your subclass, override all methods the framework declares as pure virtual. The reason these differences exist actually comes from the relationship and interactions between the DEXT families. Case in point, PCIDriverKit doesn't require a specific subclass because it wants SCSIControllerDriverKit DEXTs to be able to directly load "above" it. Note that the common mistake many developers make is leaving "IOUserService" in place when they should have specified a family-specific subclass (case 2 above). This is an undocumented implementation detail, but if there is a mismatch between your DEXT driver ("IOUserSCSIPeripheralDeviceType00") and your kernel driver ("IOUserService"), you end up trying to call unimplemented kernel methods. When a method is "missing" like that, the codegen system ends up handling that by returning kIOReturnUnsupported. One special case here is the "IOUserResources" provider. This class is the DEXT equivalent of "IOResources" in the kernel. In both cases, these classes exist as an attachment point for objects which don't otherwise have a provider. It's specifically used by the sample "Communicating between a DriverKit extension and a client app" to allow that sample to load on all hardware but is not something the vast majority of DEXT will use. Following on from that point, most DEXT should NOT include "IOMatchCategory". Quoting IOKit fundamentals: "Important: Any driver that declares IOResources as the value of its IOProviderClass key must also include in its personality the IOMatchCategory key and a private match category value. This prevents the driver from matching exclusively on the IOResources nub and thereby preventing other drivers from matching on it. It also prevents the driver from having to compete with all other drivers that need to match on IOResources. The value of the IOMatchCategory property should be identical to the value of the driver's IOClass property, which is the driver’s class name in reverse-DNS notation with underbars instead of dots, such as com_MyCompany_driver_MyDriver." The critical point here is that including IOMatchCategory does this: "This prevents the driver from matching exclusively on the IOResources nub and thereby preventing other drivers from matching on it." The problem here is that this is actually the exceptional case. For a typical DEXT, including IOMatchCategory means that a system driver will load "beside" their DEXT, then open the provider blocking DEXT access and breaking the DEXT. DEXT Launching The key point here is that the entire process above is the standard IOKit loading process used by all KEXT. Once that process finishes, what actually happens next is the DEXT-specific part of this process: IOUserServerName-> This key is the bundle ID of your DEXT, which the system uses to find your DEXT target. IOUserClass-> This is the name of the class the system instantiates after launching your DEXT. Note that this directly mimics how IOKit loading works. Keep in mind that the second, DEXT-specific, half of this process is the first point your actual code becomes relevant.

I'm trying to understand the terminology around forward vs backward references in CloudKit. Say I have two record types: User LeaderboardScore (a score belongs to a user) The score record stores a user reference: score["user"] = CKRecord.Reference( recordID: userRecordID, action: .deleteSelf ) So: LeaderboardScore → User The user record does not store any references to scores From a data-model perspective: Is this considered a forward reference (child → parent)? Or a back reference, since the score is "pointing back" to its owner? My use case is having leaderboard in my app and so i have created a user table to store all the users and a score table for saving the scores of each user of the app.

I'll try to ask a question that makes sense this time :) . I'm using the following method on NSFileManager: (BOOL) getRelationship:(NSURLRelationship *) outRelationship ofDirectoryAtURL:(NSURL *) directoryURL toItemAtURL:(NSURL *) otherURL error:(NSError * *) error; Sets 'outRelationship' to NSURLRelationshipContains if the directory at 'directoryURL' directly or indirectly contains the item at 'otherURL', meaning 'directoryURL' is found while enumerating parent URLs starting from 'otherURL'. Sets 'outRelationship' to NSURLRelationshipSame if 'directoryURL' and 'otherURL' locate the same item, meaning they have the same NSURLFileResourceIdentifierKey value. If 'directoryURL' is not a directory, or does not contain 'otherURL' and they do not locate the same file, then sets 'outRelationship' to NSURLRelationshipOther. If an error occurs, returns NO and sets 'error'. So this method falsely returns NSURLRelationshipSame for different directories. One is empty, one is not. Really weird behavior. Two file path urls pointing to two different file paths have the same NSURLFileResourceIdentifierKey? Could it be related to https://developer.apple.com/forums/thread/813641 ? One url in the check lived at the same file path as the other url at one time (but no longer does). No symlinks or anything going on. Just plain directory urls. And YES calling -removeCachedResourceValueForKey: with NSURLFileResourceIdentifierKey causes proper result of NSURLRelationshipOther to be returned. And I'm doing the check on a background queue.

Our app, BeeBot (app ID 6451085742) has been in review since January 26th. We've done the following: Submitted a support ticket (no answer) Requested expedited review (no response, expedited review window came and went) Called support (no help, just told us to wait) This is an just an update, not a new app submission. I've been doing iOS dev for over 10 years and I never have seen review times this long. There's been no communication from Apple. What's going on?

Hi developer community, First time iOS developer here. I originally submitted my iOS app for review on Friday February 20th and was asked to make a small change on Monday February 23rd, which I did promptly and resubmitted with a new build that evening. It's been a week since I resubmitted and wondering if I may have done something incorrectly when reattaching a new build to the review submission. I requested an expedited review on Friday February 27th and contacted support this morning but haven't seen any movement on the "waiting in review" status yet. My app is highly dependent on seasonality (winter sports) and I missed a key opportunity at an event last week to promote the app while the app has been stuck in review. Any guidance or assistance would be super welcome so I can get my app out into the world before we get into the Spring season! App ID: 6759411804 Thanks

Hi, For the past week, I’ve been receiving the following warning when performing a sales figures sync through AppFigures: “[Apple ID] has new terms to agree to in App Store Connect. We will try to continue importing but some data may not be available. Please log in to your App Store Connect account and accept the Terms & Conditions.” However, when I log in to App Store Connect and review the Agreements, Tax, and Banking section, there are no pending agreements or new terms requiring acceptance. All agreements appear to be active and in effect. Because the warning persists, I’m wondering whether there may be a backend agreement or updated term that is not properly surfacing in the interface. While inspecting the page, I also noticed the following console warnings on appstoreconnect.apple.com: tb-alertbox--warn ng-isolate-scope is not valid I’m not sure whether this is related, but I wanted to mention it in case it could be preventing a required agreement notice from displaying. Thank you for your assistance.

I have made an app using Xcode 26.3 Release Candidate 2 for my Apple Watch that runs successfully on the simulator. Xcode comes with the IoS 26.2 and WatchOS SDK 26.2. However, when I do try to connect to my device that have IoS 26.3 and watchOS 26.3, I see a succesful connection to my iPhone but I see the the world symbol and wheel keeps trying to connect on my Apple Watch. I also tried Xcode 26.4 beta 2 with no luck. I reviewed the WatchOS Release Notes: The watchOS 26.2 SDK provides support to develop watchOS apps for Apple Watch devices running watchOS 26.3. The SDK comes bundled with Xcode 26.2, available from the Mac App Store. I also tried Xcode 26.2 but no luck. Any suggestions?
