I'm developing a single target watchOS app that obtains HealthKit information. I have the "Background Delivery" option checked under "Signing & Capabilities" for the watch target. The app does HKObserverQueries in the foreground that work as I would expect. But when I click the Digital Crown to return to clock face, the HKObserverQuery activity stops. I'm using Xcode 15.4, on Mac 14.5 and a Apple Watch Series 4 running 10.5.

I've been trying to make my app available on the App Store for a month now, but I can't because the signatures I created don't appear in the sandbox app. I did all the configuration in the store and in the app. I tested the same code in another app with signatures and it was loaded, but the signature for that specific app doesn't appear. I've tried contacting Apple support, but they can't help me. It almost seems like it's on purpose. I'm treated like crap and they don't even give me an explanation about what's happening. Can anyone help me?

I’m running into an issue while implementing JournalingSuggestions with Xcode 16.2 and the iOS 18 simulator. My code builds and runs fine on a physical device, but it consistently crashes on the simulator and in Xcode previews. I’ve tried several workarounds, including weak linking and solutions from this post (746843), but I’m still hitting a wall. Here’s what’s happening: I get a warning: JournalingSuggestions is not available when building for iOS Simulator. This is followed by a build error: Linker command failed with exit code 1 (use -v to see invocation). What I’ve Tried: Weak linking the JournalingSuggestions framework. Applying fixes from this post (746843), such as cleaning the build folder and using weak link. Deleting Derived Data and rebuilding. Testing on a physical device (works fine). My Setup: Xcode Version: 16.2 Simulator: iOS 18 Build Success: Works on physical device, fails on simulator/preview Code: #if canImport(JournalingSuggestions) import JournalingSuggestions #endif ... var suggestionButton: some View { #if canImport(JournalingSuggestions) #if !targetEnvironment(simulator) if #available(iOS 17.2, *) { return AnyView(journalingSuggestionsPickerButton) } #endif return AnyView(disabledSuggestionButton) #else return AnyView(disabledSuggestionButton) #endif }

I'm looking for technical documentation on Apple's IEEE 754 implementation on the M1 - M4 chips. Specifically, I'd like to know how NaN payloads are handled in arithmetic operations. Does anyone know where this information is available? Thank you!

I use eapolcfg in Apple's open source eap8021x repository to connect to the enterprise network. 1.https://github.com/gfleury/eap8021x-debug https://opensource.apple.com/source/eap8021x/eap8021x-304.100.1/ Our enterprise network authentication is PEAP. So far, I have created a profile using the following commands and have done the access. ./eapolcfg createProfile --authType PEAP --SSID myssid --securityType WPA2 --userDefinedName MyProfile ./eapolcfg setPasswordItem --password mypassword --name myname --SSID myssid ./eapolcfg startAuthentication --interface en0 --SSID myssid After I performed this series of operations, I passed BOOL success = [self.interface associateToEnterpriseNetwork:network identity:nil username:username password:password error:&error]; Connection will pop up the following pop-up window, sometimes associateToEnterpriseNetwork will fail. I don't know what went wrong, is it that I missed some steps through the eapolcfg [tool?] This function also reports the following error：Error Domain=com.apple.coreWLAN.EAPOL.error Code=1 "(null)" Please answer my questions. Thank you very much

I'm currently working on transitioning to StoreKit 2. In order to see if my users are legacy users who purchased the app before I implemented an in-app purchase, I am trying to use the original purchase date for the app. Unfortunately, it's returning 0 seconds since 1970. func updateOriginalPurchaseStatus() async throws { let transaction = try await checkVerified(AppTransaction.shared) self.originalPurchaseVersion = transaction.originalAppVersion self.originalPurchaseDate = transaction.originalPurchaseDate } This is from the transaction: [3] = { key = "originalPurchaseDate" value = number (number = 0) } Currently trying to figure out when I actually purchased the app, but it might be as early as 2012. And I likely used a download code.

Apple Feedback Ticket: FB16804936 Background We develop a parental control application called Adora Kids (https://apps.apple.com/us/app/adora-kids/id6443787669) that requires "Location Always" permission to function properly. Our app has Screen Time authorization and provides monitoring services for parents. Issue We are experiencing a recurring problem where child users receive the system notification "Adora accessed your location in the background" every few days. This frequently results in children disabling location permissions, which prevents our app from functioning as intended. Current Approach and Limitations We have explored using Content & Privacy Restrictions for Location Services as a potential solution, but have encountered two significant limitations: These restrictions cannot be accessed programmatically via the ManagedSettings framework (unlike AppStoreSettings and other restrictions). The current implementation is "all-or-nothing" - enabling location restrictions blocks permission changes for ALL apps on the device, preventing children from granting legitimate location access to other applications. Questions Is there a way to programmatically access and manage Content & Privacy Restrictions for Location Services through the ManagedSettings framework that we might have overlooked? Are there any recommended approaches for apps with Screen Time authorization to prevent users from changing specific permissions (particularly location) while still allowing them to manage permissions for other apps? Does Apple have plans to implement app-specific permission locking for apps with Screen Time authorization in future iOS releases? Are there any alternative approaches or workarounds that other developers have successfully implemented for this use case? Any guidance from the developer community or Apple engineers would be greatly appreciated. This is a critical functionality issue affecting the reliability of our parental control service. Thank you in advance for your assistance.

Hi, I'm currently working on an app made originally for iOS 15. On it, I add an observer on viewDidLoad function of my ViewController to listen for changes on the UserDefault values for connection settings. NotificationCenter.default.addObserver(self, selector: #selector(settingsChanged), name: UserDefaults.didChangeNotification, object: nil) Said values can only be modified on the app's section from System Settings. Thing is, up to iOS 17, the notification fired as expected, but starting from iOS 18, the notification doesn't seem to be sent by the OS. Is there anything I should change in my observer, or any other technique to listen for the describe event? Thanks in advance.

I am developing a macOS non-interactive macOS application which does not show any ui. i want to block main thread and do all the work on worker thread . Once done with work in worker thread, want to unblock main thread by exiting event loop to terminate application. Because i dont want to show any UI or use any Foundation/Cocoa functionality, i am thinking of using CFRunLoop to block main thread from exiting until i finish my work in worker thread. When i tried this in a project, I am able to finish work in worker thread after block main thread using CFRunLoop. I also want this application to be a bundled application, which can be launched by double clicking on application bundle . But when i tried it in my xcode project by launching it using double clicking on application bundle, application keeps on toggling/bouncing in the dock menu with a status "Not responding". Although i am able to complete my work in worker thread. import Foundation let runLoop = CFRunLoopGetCurrent() func workerTask() { DispatchQueue.global().async { print("do its work") sleep(5) // do some work print("calling exit event loop") CFRunLoopStop(runLoop) print ("unblocking main thread") } } workerTask () // blocking main thread print ("blocked main thread") CFRunLoopRun() print ("exit") Why i am getting this application bouncing in doc menu behavior ? I tried by using NSApplicationMain instead of CFRunLoop in my project, in that case i didnt get this behavior . Does NSApplicationMain does some extra work before starting NSRunLoop which i am not doing while using CFRunLoop, which is showing this toggling/Bouncing application icon in Dock menu ? or Is this bouncing app icon issue is related to run loop i am using which is CFRunLoop ? Note : If i dont use a bundled application and use a commandline application then i am able to do all steps in worker thread and exit main thread as i wanted after finishing my work . But i need to do all this in application which can be launched using double clicking (bundled applcation). If not by using CFRunLoop, then how can i achive this ? - Create a application which shows no UI and do all work in worker thread while main thread is blocked. Once work is done unblock main thread and exit. And user should be able to launch application using double click the application icon.

We are building a 'server' application that can either run as a daemon or can run in background without showing any GUI. Basically, the end user can either configure this to run as a daemon so that it can be tied to the user's session or will launch the process which user will start and quit as needed. I wanted to understand what is the recommended mechanism for such an application from Apple - Should this application be built as a macOS Bundle ? Apple documentation also says that we should not daemonize the process by calling fork. Hence if we create a unix-style executable, will I not need to fork to make it run in a detached state when I launch the executable via double-click ? [Reference Link] Is it fine to have an application on macOS which is a bundle but does not show any UI when launched by double click on the app-icon or via 'open'? While we have been able to achieve this by using NSApplicationMain and not showing the UI, was wondering if using CFRunLoop is best for this case as it is a non-gui application. If we can get the right documentation link or recommendations on how we should build such an application which can run in a non-gui mode and also in a daemonized manner, it will help us. Should the application be always built as a macos bundle or should it be a unix-style executable to support both the cases - by the same application/product and how should we look at the distribution of such applications.

Currently (at least for a few days, maybe longer), when trying to create an Apple Maps Web Snapshot according to https://developer.apple.com/documentation/snapshots/generating_a_url_and_signature_to_create_a_maps_web_snapshot with a custom image marker (passed as Base64 PNG), the Apple server responds with a 500 Internal Server Error. Using the default balloon marker works, but a custom Base64 image marker used to work in the past (and still should according to the documentation).

The system calendar when showing a calendar event shows a relative timestamp on the notification versus all other apps which have a timestamp of when the notification was sent. Is there a way to set the timestamp to be relative? I am currently working on a calendar app and we should be able to use the same system that apple uses for its own calendar. Post about this on stack overflow from someone else a few years ago

The app will be wake up from killed status by silent notification or not? This is a question for years, from my test. It will wake up. Here the wake up means it will call the "didFinishLaunchingWithOptions" method. But we can not see the app in the "recent apps" list after switching home-screen up. So any Apple dev can give me a detailed explain for this?

Hello, My app has had CloudKit enabled for a while, but it's not working. I get the error "Invalid bundle ID for container". Configure CloudKit in your project from TN3164 suggests changing to a new container. I tried changing to a new container, but this leads to data loss. The article recommends: "If your CloudKit container is already used in the production environment and switching to a new container leads to data loss, consider filing a feedback report with the following information to request manually associating your CloudKit container with your app ID." Where can I request this manual association? Is there anything else I can do? Thank you for your time and assistance. I’d appreciate a prompt resolution, as this issue is blocking our update. Looking forward to guidance.

I want to update my lockscreen LiveActivity via Broadcast Push Notification, but updating always fails - but ending always works. Payload with "update" is completely ignored: {"aps":{"timestamp":1685952000,"event":"update","content-state":{"currentSlotName":"Debug1","nextSlotName":"Debug2"}}} Same payload with "end" works, the view is refreshed with the new content-state: {"aps":{"timestamp":1685952000,"event":"end","content-state":{"currentSlotName":"Debug1","nextSlotName":"Debug2"}}} Via the MacOS Console I am able to see that both events happen to end up on the device. I am sending these Broadcast Push Notifications via Apple's Push Notifications Console.

I use Homepod Mini as the gateway and have bound 9 Matter lights and 7 Matter switches. Each of my switches has 12 buttons, and each button supports three functions: single click, double click, and long press. Therefore, a total of 252 actions can be configured for 7 * 12 * 3. Currently, a total of 71 actions are configured for the 7 Matter switches. When configuring the 72nd action, the app will prompt that the operation cannot be completed. But if you delete a few previously configured actions, such as 68 actions, then you can configure 3 more actions (69, 70, 71). However, as long as you configure the 72nd action, the app will prompt that the operation cannot be completed, as if the available space is occupied. What is the reason for this?

In my app, I've been using ModelActors in SwiftData, and using actors with a custom executor in Core Data to create concurrency safe services. I have multiple actor services that relate to different data model components or features, each that have their own internally managed state (DocumentService, ImportService, etc). The problem I've ran into, is that I need to be able to use multiple of these services within another service, and those services need to share the same context. Swift 6 doesn't allow passing contexts across actors. The specific problem I have is that I need a master service that makes multiple unrelated changes without saving them to the main context until approved by the user. I've tried to find a solution in SwiftData and Core Data, but both have the same problem which is contexts are not sendable. Read the comments in the code to see the issue: /// This actor does multiple things without saving, until committed in SwiftData. @ModelActor actor DatabaseHelper { func commitChange() throws { try modelContext.save() } func makeChanges() async throws { // Do unrelated expensive tasks on the child context... // Next, use our item service let service = ItemService(modelContainer: SwiftDataStack.shared.container) let id = try await service.expensiveBackgroundTask(saveChanges: false) // Now that we've used the service, we need to access something the service created. // However, because the service created its own context and it was never saved, we can't access it. let itemFromService = context.fetch(id) // fails // We need to be able to access changes made from the service within this service, /// so instead I tried to create the service by passing the current service context, however that results in: // ERROR: Sending 'self.modelContext' risks causing data races let serviceFromContext = ItemService(context: modelContext) // Swift Data doesn't let you create child contexts, so the same context must be used in order to change data without saving. } } @ModelActor actor ItemService { init(context: ModelContext) { modelContainer = SwiftDataStack.shared.container modelExecutor = DefaultSerialModelExecutor(modelContext: context) } func expensiveBackgroundTask(saveChanges: Bool = true) async throws -> PersistentIdentifier? { // Do something expensive... return nil } } Core Data has the same problem: /// This actor does multiple things without saving, until committed in Core Data. actor CoreDataHelper { let parentContext: NSManagedObjectContext let context: NSManagedObjectContext /// In Core Data, I can create a child context from a background context. /// This lets you modify the context and save it without updating the main context. init(progress: Progress = Progress()) { parentContext = CoreDataStack.shared.newBackgroundContext() let childContext = NSManagedObjectContext(concurrencyType: .privateQueueConcurrencyType) childContext.parent = parentContext self.context = childContext } /// To commit changes, save the parent context pushing them to the main context. func commitChange() async throws { // ERROR: Sending 'self.parentContext' risks causing data races try await parentContext.perform { try self.parentContext.save() } } func makeChanges() async throws { // Do unrelated expensive tasks on the child context... // As with the Swift Data example, I am unable to create a service that uses the current actors context from here. // ERROR: Sending 'self.context' risks causing data races let service = ItemService(context: self.context) } } Am I going about this wrong, or is there a solution to fix these errors? Some services are very large and have their own internal state. So it would be very difficult to merge all of them into a single service. I also am using Core Data, and SwiftData extensively so I need a solution for both. I seem to have trapped myself into a corner trying to make everything concurrency save, so any help would be appreciated!
