Hello, I'm trying to figure out why an Int is being inferred over my explicit Double I'm parsing a CSV that contains 2 tables. I don't own the data so I'm not able to change it. The first row contains one cell that's used as a title for the document The second row is empty The third row contains one cell that's used as the header for the first table There is a header row for the table There's a dynamic number of rows for this table The an empty spacer row There is a row that's used as a title for the second table There is a header row for the table There's a dynamic number of rows for this table Im able to separate and create two DataFrame's from the data without issue. And this is the initializer I'm using. DataFrame( csvData: csvData, rows: rows, types: types, options: options ) Column names and their CSV types looks like this var types: [String: CSVType] { [ // ... "Column 38": .double, // ... ] } The data in the CSV is 0 nil nil nil 2 And this is what the one of the columns in question looks like when printed ▿ 38 : ┏━━━━━━━━━━━┓ ┃ Column 38 ┃ ┃ <Int> ┃ ┡━━━━━━━━━━━┩ │ 0 │ │ nil │ │ nil │ │ nil │ │ 2 │ └───────────┘ - name : "Column 38" - count : 5 ▿ contents : PackedOptionalsArray<Int> ▿ storage : <PackedOptionalsStorage<Int>: 0x600000206360> The docs state /// - types: A dictionary of column names and their CSV types. /// The data frame infers the types for column names that aren't in the dictionary. Since types contains the column name and it's still being inferred, my assumption is that the issue involves the renaming of the header row when it has empty cells occurs after the types are checked. Edit: After setting hasHeaderRow: false from true and adjusting my row offset, the types are now being assigned correctly. I'd recommend opening a feedback enhancement where renaming columns occurs before type assignment.

Some users have switched to wearing smart rings instead of an Apple Watch, but they still want their rings to close throughout the day in Apple Fitness to keep their streaks going. I've noticed that the 3rd party smart ring apps do not affect the progress of the exercise and move rings unless the user puts on their Apple Watch and syncs with there iPhone throughout the day. Is there a way to make the progress rings update throughout the day without having to connect an Apple Watch periodically?

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.

Greetings fellow devs, After accepting the Alternative Terms Addendum for Apps in the EU and adding the Storekit External Purchases or Offers capability via App Store Connect in our app identifier, the entitlement showing up in xcode is com.apple.developer.storekit.custom-purchase-link.allowed-regions and has the value 'jp'. How can we change the value for that entitlement to 'gr'? We tried changing it in xcode, but we get the error <Provisioning profile "iOS Team Provisioning Profile: [app identifier]" doesn't match the entitlements file's value for the com.apple.developer.storekit.custom-purchase-link.allowed-regions entitlement.>. In Certificates, Identifiers and Profiles in the developer account there is no way to configure that capability. We sent a request to support and they only gave a link to documentation and to the forum here. We have a completed every business agreement requested and we have chosen Greece as the organisation region and the app's availability region wherever possible. We haven't found anywhere that Japan would be chosen to explain the entitlement given. So where can this entitlement about allowed regions be configured? Xcode version is 16.4 and iOS minimum deployments is 18

We're working on in-app provisioning for wallet access passes. When testing the in-app provisioning on a sandbox account, I get an error saying software update required. Please advise.

macOS 26.4 Beta appears to have changed how built-in MacBook keyboard events are routed through IOHIDSystem. Third-party virtual HID devices loaded via DriverKit no longer receive events from the built-in keyboard. External keyboards are unaffected. This is already confirmed across multiple users: https://github.com/pqrs-org/Karabiner-Elements/issues/4402 One possible lead (from LLM-assisted code analysis, not independently verified): this could be related to a security policy referred to as com.apple.iohid.protectedDeviceAccess, which may block IOHIDDeviceOpen for the Apple Internal Keyboard via SPI transport (AppleHIDTransportHIDDevice). A "GamePolicy" check in IOHIDDeviceClass.m that gates HID device access could be involved. This is a hint, not a confirmed root cause. The impact goes well beyond a single project. Keyboard remapping on macOS is a thriving ecosystem — used for accessibility, ergonomics, developer productivity, and multilingual input. This is one of macOS's strengths as a platform. Many professionals specifically choose Mac because this level of customization is possible. If this capability is being removed without an alternative, it would significantly diminish what makes macOS attractive for power users and developers. Is this an intentional architectural change to the input event pipeline for built-in keyboards, or a beta regression? If intentional, what is the recommended alternative for developers?

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?

Hi, On macOS 26.4 Beta (25E5218f) （macOS Tahoe 26 Developer Beta ）, the network filter causes network failures or slowdowns. This manifests as Chrome failing to access websites, while Safari can access the same websites without issue. The affected websites can be pinged locally. My situation is similar to this situation.The same question link is: https://github.com/objective-see/LuLu/issues/836 Have you been paying attention to this issue? Hopefully, it can be fixed in the official release. Thank you.

From the Feb 24 news, I understand that for all Apple users in Brazil with iOS26.2 and newer, isEligibleForAgeFeatures will eventually return true. Brazil is a "nonregulated region", and developers will need to handle all three situations of ask first/always share/never share. Please correct me if I'm wrong above. A few questions follow on the eligibility check: What's the return value of IsEligibleForAgeFeatures for a Brazilian user who has NOT touched the age range feature at all, thus hasn't picked one of the three options? How can we test these cases? From the updated sandbox doc, there's more information on declined/approved, will those the same behaviors as a future Brazilian user? The doc used to say Texas, now it doesn't say any region. On which date will Apple START to return true for IsEligibleForAgeFeatures for Brazilian users? I cannot find the exact date anywhere. Will ALL of Brazil return true overnight, or is there some ramp up that developers need to be aware of? Thanks a lot for sharing the guidance, and thanks in advance for more guidance to come!

Hi all, I’m facing a device-specific issue in a live production iOS app distributed privately via the App Store . The app crashes immediately after login on one client’s iPhone, while the same account works fine on other devices. There’s no crash log generated in Analytics, and the app just pops to the home screen. Environment: App: Production app on App Store iOS version: 26.3 Devices: Only one device exhibits the crash; other iPhones work fine Login flow: App calls an API and writes the response to a local SQLite database immediately after login Distribution: App Store (Privately). The user is install via the redemption codes. Observations: All users on the problematic device crash immediately after login. The crash does not occur on any other devices, including the same iOS version. The client had already uninstalled and reinstalled the app via App Store cloud download, but the crash persisted. No crash log appears in Analytics or Xcode (process just terminates). Device restart had not been attempted before reinstall. App does not use Keychain tokens; local DB is only SQLite in the app sandbox. Hypotheses so far: Corrupted binary or cached app installation on that device SQLite database corruption or write failure Device-specific OS/environment issue (temp files, file locks, provisioning) iOS watchdog silently terminating the app during post-login DB write Language / region differences unlikely Questions: Is it possible for a device to retain a corrupted app binary or cached installation even after uninstall + cloud download reinstall from the App Store? Can uninstalling, restarting the device, and reinstalling guarantee a fresh binary and sandbox? Are there any known iOS behaviors where a local SQLite write could trigger an instant crash on one device only, without generating crash logs? Any other suggestions for diagnosing this device-specific post-login crash in a live production environment? Thanks in advance for any guidance — this issue is affecting a client’s live usage, and we’d like to understand the root cause and best way to resolve it safely.

Hi Apple Network Team, Good day. Recently we are experiencing some issues that when iOS or iPad OS connected to a Wi-Fi with captive portal, iOS sometimes failed to launch the full captive portal website. Based on TCPDump and WLAN dump logs, when this failure happened, we only see web client on iOS queried AAAA and HTTPS DNS queries without A query. Not all the websites are supporting and being hosted on both IPv4 and IPv6 servers. Is there a know bug on iOS and iPad OS side including OS version >= 36.2.

Dears, We are developing an apple wallet extension. In the Non-ui extension, in the getPaymentPassEntry overriden function we have to return an object such as: ``PKIssuerProvisioningExtensionPaymentPassEntry(identifier: identifier, title: label, art: getEntryArt(image: uiImage), addRequestConfiguration: requestConfig)!`` What is not clear are the requirements for this "art" parameter. Somewhere in the FAQ it says that the art has to be an image of 1536 x 969 resolution, <4 MB, squared corners, no chip contacts, and so forth) but we set there images of any size and the extension displays them without any problem. Are those requirements (1536 x 969 resolution, and so on) only for the images that are displayed in the wallet only after the card has been added? In this case, are those images coming from the PNO directly and not coming from the function above which is in the wallet extension? Thanks,

Good afternoon all, I have a question about Live Activities, specifically ProgressView. Why are they so hard to customize? You can't even really, consistently make the bar a specific height in points. You can't provide any progress view style to make it richer and more dynamic. We want to build a progress bar that's built up of 3 components: a track with its value constant on 1.0 (the full progress) with a specific color, another track that's the actual progress from ProgressView(timerInterval:countsDown:), and some way to create a visual gap in between. The progress bar should also be bigger than the standard size from iOS, but that's also not possible. The corners become really ugly when you use the scaleEffect modifier. Please, if anyone has any ideas about customizing the ProgressView without me having to send push notifications to manually make sure the bar updates, comment down below.

I developed a cloud drive using fskit, but after mounting it, it did not appear in the Finder sidebar and the disk tool could not list it. How should I adapt? The mounting looks successful, and you can also open and see the fixed files I wrote in the code. I have also turned on the Finder sidebar settings function

Dear Apple Developer Support Team, I am writing to inquire about the process for obtaining approval for the following entitlement in my iOS/macOS app: <key>com.apple.developer.networking.networkextension</key> <array> <string>content-filter-provider</string> </array> Specifically, I would like guidance on: The steps required to submit a request for this entitlement. Any necessary documentation or justification that needs to be provided to Apple. Typical review timelines and approval criteria. Any restrictions or compliance requirements associated with this entitlement. Our app intends to implement a content filtering functionality to enhance network security and user safety. We want to ensure full compliance with Apple’s policies and guidelines. Could you please provide detailed instructions or point us to the relevant resources to initiate this approval process? Thank you for your assistance.

We are currently experiencing an issue that occurs only on iPhone 17 models. In our app, after connecting to an external device, users can download multiple video files stored on the device. When downloading several videos consecutively, the device consistently stops receiving responses midway through the process. As a result, no response is returned, and the connection between the app and the device is eventually lost. This issue does not occur on any iPhone models prior to iPhone 17. It is reproducible across all iPhone 17 devices within our company. This is a critical issue, and we need urgent assistance. The main error logs show two patterns: • Connection loss • Timeout At the OS level, the only error codes we receive are: • -1005 (Network connection lost) • -1001 (Request timed out) Unfortunately, we are unable to obtain more detailed error information beyond these codes, which makes further debugging difficult. We have attached the relevant logs below. We would greatly appreciate any guidance on how to further investigate or resolve this issue. 310.0 / :: 81 % ::: 251.21481481481482 310.0 / :: 82 % ::: 254.23280423280423 310.0 / :: 83 % ::: 257.3820105820106 310.0 / :: 84 % ::: 260.4 KeepAlive SEND id=423F1336-6239-4B3B-9414-5A987D85D564 at=2026-02-24T12:56:43Z timeout=60.000000s current: D20-Q2-PLUS, ssid: D20-Q2-PLUS_136a63 KeepAlive SKIP (in-flight) tcp_output [C10.1.1:3] flags=[R.] seq=4017430266, ack=4146413113, win=2048 state=CLOSED rcv_nxt=4146413113, snd_una=4017429847 nw_read_request_report [C10] Receive failed with error "Operation timed out" nw_flow_add_write_request [C10 192.168.000.0:443 failed parent-flow (satisfied (Path is satisfied), interface: en0[802.11], ipv4, dns, uses wifi, LQM: good)] cannot accept write requests nw_write_request_report [C10] Send failed with error "Socket is not connected" Task <5BDBE621-329A-45E9-B236-9C173E92A41F>.<7> HTTP load failed, 361/0 bytes (error code: -1005 [4:-4]) Task <5BDBE621-329A-45E9-B236-9C173E92A41F>.<7> finished with error [-1005] Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

Most of the issues occur during this keepalive process, and this is when the logs mentioned earlier are generated. Based on our debugging so far, the keepalive function itself is being called as expected. However, the execution appears to stall while waiting for a response from the device. After remaining in that state for some time, the session eventually ends with either a timeout or a connection loss error. We are use almofire 4.0.1. According to the firmware developer, when this issue occurs, there are no corresponding values or logs received on the device side. Therefore, we are currently investigating whether this might be related to a networking issue on the iPhone side. All other features are functioning normally. The problem occurs only when downloading VOD video files, and the reproduction rate is 100% under that condition.

I have some questions related to MPAN. What is the format of an MPAN? Is it the same as DPAN? Is it PAN preserving format? Is a Cryptogram required and if yes, what kind of cryptogram? Is it the same format as DPAN? Thanks in Advance!

Right now, I am scanning for specific BLE peripherals with my iPad app, using this: [self.cbCentralManager scanForPeripheralsWithServices:serviceUUIDsToScanFor options:@{CBCentralManagerScanOptionAllowDuplicatesKey:@YES}]; I have the "CBCentralManagerScanOptionAllowDuplicatesKey" set true because I need to be able to detect when a peripheral is no longer advertising, so I capture each "didDiscoverPeripheral" callback and set a 3-second timer that notifies the user that that peripheral is no longer in range if another didDiscoverPeripheral hasn't been received in that time. The peripherals all advertise at 100ms intervals. What's weird is that if I leave the scan on for a long time, the advertising packets slow down, and eventually one of those timers times out, around about one or two minutes for the first instance, and then every 10-20 seconds after that. I've checked with ATS for all the BLE traffic, and there are indeed > 3-second gaps in the advertising packets that the iPad sees, so it's not my code introducing the gap. Is there some reason long-running scans should not be done on iPadOS (both 18 and 26.1 used)? I've tested out switching my scan to "stopScan" and restart it every 10 seconds, and that seems to have resolved the issue, but it's unclear why that would matter (and that does not seem like an appropriate use of the stop and start scans). Thanks!

I'm working on an editor for Bevy games and wanted the following workflow: Launch the game process Host a Metal view for the game's render target Use an XPC service to transfer an MTLSharedTextureHandle Keep the connection for editor/game communication and hot reload As such I created the following editor service: public let XPCEditorServiceName = "org.bevy.editor" public enum XPCEditorMessage: Codable { case ping } public enum XPCEditorReply: Codable { case pong } extension XPCListener { static let bevy = try! XPCListener(service: XPCEditorServiceName) { request in request.accept(XPCEditorService.init) } } struct XPCEditorService: XPCPeerHandler { let session: XPCSession private func handle(_ message: XPCEditorMessage) -> XPCEditorReply? { switch message { case .ping: return .pong } } func handleIncomingRequest(_ message: XPCReceivedMessage) -> (any Encodable)? { do { return handle(try message.decode()) } catch { return nil } } func handleCancellation(error: XPCRichError) { print(error) } } and I initialize it in my app's App initializer: // Launch the XPC service print(XPCListener.bevy) I wanted to test this using an executable target with the following main.swift: let session = try XPCSession(xpcService: XPCEditorServiceName) let response: XPCEditorReply = try session.sendSync(XPCEditorMessage.ping) print("Connected to editor!") The editor prints Listener<org.bevy.editor>(Active) but the game fails with Underlying connection was invalidated. Reason: Connection init failed at lookup with error 3 - No such process What am I doing wrong? PS. Would also appreciate an example of sending & rendering the MTLSharedTextureHandle both in editor & game.
