I'm working on an XPC server and need to determine the owner of the client process that connects to it. Specifically, I'd like to retrieve details such as the fully qualified user name or other identifying information from the XPC client connection.I'm considering using xpc_connection_get_pid() to get the client’s process ID, but I’m unsure of the best way to map this to the user who owns the process. Is there a recommended API or approach to capture this information securely?

Hi Folks, We are reading the USB device data from our app using libusb/iokit libraries. Before updating the MacOS to the 15.3 we never faced any issue but after updating OS to 15.3 Sequoia we started facing issue to access the USB device's information. We are not getting the device endpoints for the matching service and fails with below error- Error:Failed to create IOUSBHostObject. with reason: IOServiceOpen failed. Respective code snippet- service = IOServiceGetMatchingService(kIOMasterPortDefault, matchingDictionary); IOUSBHostInterface* interface = [[IOUSBHostInterface alloc] initWithIOService:service options:IOUSBHostObjectInitOptionsDeviceCapture queue:*queue error:&error interestHandler:nil]; We get the denial message during accessing the IOService error 23:17:30.691934-0800 kernel 41 duplicate reports for Sandbox: spotlightknowledged(1399) deny(1) mach-lookup com.apple.diagnosticd error 23:17:30.691945-0800 kernel System Policy: com.prograde.pgdrefreshpro.helpe(70515) deny(1) iokit-open-service IOUSBHostInterface Also when we checked the IOUSBHOST logs we can see pipes are stalled while running the RefreshPro app as below- 2025-02-05 22:06:31.838141-0800 0x25913e Error 0x0 0 0 kernel: (IOUSBHostFamily) AppleUSBIORequest: AppleUSBIORequest::complete: device 8 (SD PG05.5@08210000) endpoint 0x00: status 0xe0005000 (pipe stalled): 0 bytes transferred We need an assistance here to know what exactly could be the cause and how can we elevate the permissions to access the USB device on MacOS15.3. Do we need other entitlements? As we never faced such issue with our certificate and Identifier on any MacOS versions and with the current entitlements we have. Do we need to include any entitlement in the code? Thanks.

Good morning, I'm encountering reliability issues with DDC/CI communication when using USB-C connection. Initially using ddc-hi (which uses this package), I ran into several issues that I've partially resolved but still need help addressing. Environment OS: macOS Display Connection: USB-C for _ in 1 ... (numOfRetryAttemps ?? 4) + 1 { for _ in 1 ... max((numOfWriteCycles ?? 2) + 0, 1) { usleep(writeSleepTime ?? 10000) success = IOAVServiceWriteI2C(service, UInt32(ARM64_DDC_7BIT_ADDRESS), UInt32(dataAddress), &packet, UInt32(packet.count)) == 0 } if !reply.isEmpty { usleep(readSleepTime ?? 50000) if IOAVServiceReadI2C(service, UInt32(ARM64_DDC_7BIT_ADDRESS), 0, &reply, UInt32(reply.count)) == 0 { success = self.checksum(chk: 0x50, data: &reply, start: 0, end: reply.count - 2) == reply[reply.count - 1] } } if success { return success } usleep(retrySleepTime ?? 20000) } The result from IOAVServiceReadI2C is not reliable in some cases. Do we have any other API to get VCP code from monitor like Intel version done. The previous APIs weren’t working anymore on the M1 GPU, the IOFramebuffer was now an IOMobileFramebuffer and the IOI2C* functions weren’t doing anything.

I was trying to call getsockopt(fd, SOL_LOCAL, LOCAL_PEERCRED, ...), and by mistake passed a wrong value for the second parameter where it should be SOL_LOCAL. But the call still succeeded. Then I did more experiments and passed more random values for the second parameter, all succeeded. It seems there is a lack of parameter check in the implementation of getsockopt() , where it should return errors if people pass invalid parameters instead of succeeding silently. Hope the Apple engineers can help to validate and fix it.

Hi, I’m trying to perform UWB ranging between an iPhone and a Qorvo DWM3001CDK accessory using Apple NI’s NINearbyAccessoryConfiguration class. I’ve followed the steps described in the official Apple documentation (https://developer.apple.com/documentation/nearbyinteraction/ninearbyaccessoryconfiguration), specifically for enabling background mode using the init(accessoryData:bluetoothPeerIdentifier:) initializer. The configuration is successfully created, and background mode is enabled. However, when the iPhone starts the session, I doesn’t receive any ranging data from the DWM3001CDK, and the session ends with a timeout. Interestingly, if I use the init(data:) initializer, I can successfully receive ranging data, but this only works in foreground mode, which doesn’t meet my requirements. Steps I’ve followed: Used Core Bluetooth to discover and pair the accessory. Retrieved the configuration data from the accessory according to the third-party UWB device specifications. Initialized the configuration using NINearbyAccessoryConfiguration(accessoryData:bluetoothPeerIdentifier:) for background mode. Started the session with NISession.run(configuration). Waited for updates in the delegate method session(_:didUpdate:). Specific questions: Are there additional requirements for using init(accessoryData:bluetoothPeerIdentifier:) to enable background UWB ranging with the DWM3001CDK? Is there a known difference in how init(data:) and init(accessoryData:bluetoothPeerIdentifier:) handle the ranging process? Any advice or insights would be greatly appreciated. Thanks in advance!

Widgets on the widget is not responding to the touch properly. This issue is also affecting within the home screen widget in a way that the widget switches to light mode by itself even though I am in dark mode. Additionally, lock screen does not to respond once the lock screen widget has been edited. Is anyone else having this issue?

Hi all, we are a Software company located in the EU. Or focus is building solutions for closed-loop fuel cards. To allow our customers to move to "virtual" closed-loop cards, we would like to request a HCE Entitlement. When filling the HCE entitlement form non of the provided Use Cases seemed to cover our case. In addition I'm unsure if AID Prefixes are mandatory for the closed-loop use case our App is meant for. I would like to avoid starting an HCE entitlement process with incorrect parameters and delay the overall process due to this. Thanks for any insights / feedback in advance.

Hello, in the sample code found in the Apple CardSession documentation, there are commented line in the APDU respond method: case .received(let cardAPDU): do { /// Call handler to process received input and produce a response. let responseAPDU = ProcessAPDU(cardAPDU.payload) try await cardAPDU.respond(response: responseAPDU) } catch { /// Handle the error from respond(response:). If the error is /// CardSession.Error.transmissionError, then retry by calling /// CardSession.APDU.respond(response:) again. } in the catch part, it says that we should handle the error from respond and retry in case of transmission error, how can we achieve that ? How can we check the error ? Could you give a sample code for that ? best regards

Hello is there a way to only allow credit card that is from a certain country to access in-app subscription in my app? Lets say I will only allow credit card from Singapore. I don't think its possible with In-App purchase but my colleague wanted to know and I just wanted to double check here.

I have a very simple CoreData model that has 1 entity and 2 attributes. This code works fine: .onChange(of: searchText) { _, text in evnts.nsPredicate = text.isEmpty ? nil :NSPredicate(format: "eventName CONTAINS %@ " , text ) but I'd like to also search with the same text string for my second attribute (which is a Date). I believe an OR is appropriate for two conditions (find either one). See attempted code below: evnts.nsPredicate = text.isEmpty ? nil : NSPredicate(format: "(eventName CONTAINS %@) OR (dueDate CONTAINS %i) " , text ) This crashes immediately %@ does the same. Is there a way to accomplish this? How is SwiftUI not an option below?

So I'm wondering if Apple makes commission on those payments since they're made in the app. For example a user may pay another user to clean their car. This will be handled with Stripe Connect and their balance, payment history, etc will be displayed in the app. Does Apple charge commission on that? The section the app review guidelines that I'm refrencing is below, but I'm still a little confused. 3.1.3(e) Goods and Services Outside of the App: If your app enables people to purchase physical goods or services that will be consumed outside of the app, you must use purchase methods other than in-app purchase to collect those payments, such as Apple Pay or traditional credit card entry.

According to my experiments SwiftData does not work with model attributes of primitive type UInt64. More precisely, it crashes in the getter of a UInt64 attribute invoked on an object fetched from the data store. With Core Data persistent UInt64 attributes are not a problem. Does anyone know whether SwiftData will ever support UInt64?

Howdy! I'm in the R&D phase of this project and I need help. I can't find any sources that verify what I want to do is even possible. I need to connect an iPhone or iPad using a USB cord to an external device which will transfer files to the iPhone or iPad. I have an app already made which can organize the files and whatever else I need to do (app is from a similar project). I'll refer to this device as Alfred (for poops and giggles) The plan (if possible) is for Alfred to recognize my app and use its documents folder as the destination of the transfer. The iDevice doesn't have to communicate with Alfred, but that would be a bonus. I don't want Alfred to run on an SOC. My goal is to have it be as simple as possible. No OS, just firmware. If the only way to interact with Apple Devices is Bluetooth or Wifi than so be it. If Matter or Thread could be utilized I wouldn't be apposed. Any help with this project would be greatly appreciated. Thanks in advance.

In my app I need to have access to the users desktop, and I would like to implement the standard dialogue for the user to give permission for this access at launch. I do not want to use the NSOpenPanel() for the user to select the desktop, as I dont think that is an elegant solution. However I am having issues implementing this. I use the following code to be granted access to the Desktop URL: let accessGranted = desktopURL.startAccessingSecurityScopedResource() However no dialogue box appears and the call returns false I have also included "Desktop Usage Description" in my plist. Here is my code @State var message:String = "Good Luck!" var body: some View { VStack { Button("Get Desktop files") { accessDesktopWithPermission() } Text(message) } .padding() } //: –—–—–—–—–—–—–—–—–—–—–—–—–—–— :// func accessDesktopWithPermission(){ guard let desktopURL = getDesktopURL() else{ return } let accessGranted = desktopURL.startAccessingSecurityScopedResource() if accessGranted{ if let content = try? FileManager.default.contentsOfDirectory(at: desktopURL, includingPropertiesForKeys: nil ){ message = "Found \(content.count) on Desktop" } else{ message = "issue loading file from desktop" } } else{ message = "Access denied to:\(desktopURL )" } } obviously I have setup something incorrectly so I have also attached my code if anyone is interested to take a look.

Hi all, I have a simple prototype subscription for a recurring monthly for $0.29 cheap! And it works great! But it only works great at sub time. It's stuck in the sandbox, constantly giving me "currently subscribed" status even though I’ve done a bunch of things: Force-quit the app. Deleted and re-installed it. Rebooted my phone. Signed out of media purchases. Looked on AppStore connect to try to find anything that seems like it’d let me fix this All efforts in vain. I'm trying to avoid fully logging out of my iCloud account on my phone. Any other thoughts?

I am writing to seek clarification on two technical issues related to iOS frameworks (CoreBluetooth and NetworkExtension). These observations are critical for optimizing our app's performance, and I would appreciate any official guidance or documentation references. CoreBluetooth Scanning Frequency and Cycle Issue: We noticed inconsistent BLE device discovery times (ranging from 0.5s to 1.5s) despite the peripheral advertising at 2Hz (500ms interval). Questions: Does iOS regulate the BLE scan interval or duty cycle internally? If yes, what factors affect this behavior (e.g., foreground/background state, connected devices)? Are there recommended practices to reduce discovery latency for peripherals with fixed advertising intervals? Is there a way to configure scan parameters (e.g., scan window/interval) programmatically, similar to Android's BluetoothLeScanner? Test Context: Device: iPhone 13 mini (iOS 17.6.1) Code: CBCentralManager.scanForPeripherals(withServices: nil, options: [CBCentralManagerScanOptionAllowDuplicatesKey: true]) NEHotspotConfigurationManager Workflow and Latency Issue: Using NEHotspotConfigurationManager.shared.apply(_:) to connect to Wi-Fi occasionally takes up to 8 seconds to complete. Questions: What is the internal workflow of the apply method? Does it include user permission checks, SSID scanning, authentication, or IP assignment steps? Are there known scenarios where this method would block for extended periods (e.g., waiting for user interaction, network timeouts)? Is the latency related to system-level retries or radio coexistence with other wireless activities (e.g., Bluetooth)? Test Context: Configuration: NEHotspotConfiguration(ssid: "TestSSID") Behavior: Delay occurs even when the Wi-Fi network is in range and credentials are correct.
