BGTaskScheduler crashes on iOS 18.4
I've been seeing a high number of BGTaskScheduler related crashes, all of them coming from iOS 18.4. I've encountered this myself once on launch upon installing my app, but haven't been able to reproduce it since, even after doing multiple relaunches and reinstalls. Crash report attached at the bottom of this post. I am not even able to symbolicate the reports despite having the archive on my MacBook: Does anyone know if this is an iOS 18.4 bug or am I doing something wrong when scheduling the task? Below is my code for scheduling the background task on the view that appears when my app launches: .onChange(of: scenePhase) { newPhase in if newPhase == .active { #if !os(macOS) let request = BGAppRefreshTaskRequest(identifier: "notifications") request.earliestBeginDate = Calendar.current.date(byAdding: .hour, value: 3, to: Date()) do { try BGTaskScheduler.shared.submit(request) Logger.notifications.log("Background task scheduled. Earliest begin date: \(request.earliestBeginDate?.description ?? "nil", privacy: .public)") } catch let error { // print("Scheduling Error \(error.localizedDescription)") Logger.notifications.error("Error scheduling background task: \(error.localizedDescription, privacy: .public)") } #endif ... } 2025-02-23_19-53-50.2294_+0000-876d2b8ec083447af883961da90398f00562f781.crash

CloudKit not working properly in iOS 17 RC
CloudKit was working perfectly in iOS 16. However after updating to iOS 17 RC on my devices iCloud sync no longer works properly. The app has a package called CloudKitSyncMonitor which shows the sync status. Normally it would say Synced with iCloud but on iOS 17 it is either stuck in the Syncing or Sync not started state and the data doesn’t update. This mostly happens after a reinstall of the app. After some time it randomly decides to work until I uninstall the app. I’m really confused what could be the problem if it was working fine on iOS 16 but barely works properly on iOS 17? This is currently the code I have for the DataController: import SwiftUI import CoreData class DataController { var container: NSPersistentCloudKitContainer @AppStorage(wrappedValue:true,"syncEnabled",store:UserDefaults(suiteName: "group.com.ip18.SubManager")) var syncEnabled static let shared = DataController() init() { container = NSPersistentCloudKitContainer(name: "Subscriptions") load(syncEnabled: syncEnabled) } func load(syncEnabled: Bool = true) { container = NSPersistentCloudKitContainer(name: "Subscriptions") let url = URL.storeURL(for: "group.com.ip18.SubManager", databaseName: "Subscriptions") let storeDescription = NSPersistentStoreDescription(url:url) if syncEnabled { storeDescription.cloudKitContainerOptions = NSPersistentCloudKitContainerOptions(containerIdentifier: "iCloud.com.ip18.SubManager") } else { storeDescription.cloudKitContainerOptions = nil } let remoteChangeKey = "NSPersistentStoreRemoteChangeNotificationOptionKey" storeDescription.setOption(true as NSNumber, forKey: remoteChangeKey) storeDescription.setOption(true as NSNumber, forKey: NSPersistentHistoryTrackingKey) container.persistentStoreDescriptions = [storeDescription] container.viewContext.automaticallyMergesChangesFromParent = true /* // Only initialize the schema when building the app with the // Debug build configuration. #if DEBUG do { // Use the container to initialize the development schema. try container.initializeCloudKitSchema(options: []) } catch { // Handle any errors. } #endif */ container.loadPersistentStores(completionHandler: {(storeDescription,error) in if let error = error as NSError? { fatalError("Unresolved error \(error)") } }) } }

Are alternate app icons supported for visionOS apps?
I have ported my app to visionOS but have not been able to get alternate app icons working using UIApplication.shared.setAlternateIconName. I remember many months ago when I ran the iPad app directly, changing the app icon worked but I never managed to get it to work for native visionOS apps. Is this not supported for apps compiled natively for visionOS?

How can I set app shortcut platter background colour on visionOS?
This is a follow up to my previous post, this time using the visionOS 1.2 simulator and Xcode 15.4. I am trying to set the background colour of my app shortcut platter for the visionOS version using NSAppIconComplementingColorNames but it doesn’t take effect when I check the shortcuts app. I see the built in Music Recognition app has a background colour but I am unable to set one for my app. Please note that this feature is working correctly on iOS. But on visionOS it has no effect and returns a plain background. I noticed the documentation doesn't mention it works on visionOS. But if that's the case how was the music recognition app able to set a colour?

How can I revoke one time purchases made via TestFlight?
Before I launched my app, I ran a TestFlight beta program and also included a one time purchase in the TestFlight build to test the functionality. Now that the app is available in the App Store, I had closed the TestFlight program, but am looking to reopen it again to test iOS 18 specific features. The issue is, the beta testers that previously purchased the IAP on TestFlight but didn't actually purchase the IAP on the App Store version would be able to use the paid features of the app for free as long as they have the TestFlight build. Therefore I would like to revoke all the purchases made via the TestFlight build. Is there any way to do that?

Cannot navigate to external webpages from internal extension pages
In iOS 18, internal extension pages cannot navigate to external webpages, either via href links or through JS methods such as window.location.replace. Nothing happens when you try to navigate to an external webpage. Only other internal pages can be navigated to. This wasn't an issue on previous versions of iOS. It would be appreciated if this can be fixed as soon as possible. Feedback ID: FB14194963

Back button is not visible when navigating from a view with no toolbar to a view with a toolbar button on macOS 15.4 beta
On macOS 15.4 beta 2 (24E5222f), the back button is not visible when navigating from a view with no toolbar to a view with a toolbar button. The back button is visible on macOS 15.3.1 and earlier versions. Also, the toolbar button shown when run on macOS 15.4 beta 2 is truncated. This is how it looks on macOS 15.4 beta 2: And this is how it looks on macOS 15.3.1 and earlier: Feedback ID: FB16743834

Dividers not appearing in menu bar on iPadOS 26
On macOS 26 I can see the dividers when I open my Help menu: However, on iPadOS 26 the dividers don't appear: I am simply using Divider() to separate my menu bar items in my CommandGroup. iPadOS does support dividers as I can see them for the system generated Edit menu but for some reason it's not working here. Does anyone know if I am doing something wrong with the iPadOS implementation?

LAContext.biometryType now requires visionOS 2.0 in Xcode 16
On Xcode 15.4, LAContext.biometryType had an @available attribute of visionOS 1.0. However, in Xcode 16, the @available attribute for biometryType was changed to a visionOS 2.0 minimum requirement, preventing the app from building if the minimum deployment target is earlier than visionOS 2.0. This was the attribute on Xcode 15.4: This is the attribute on Xcode 16: Feedback ID: FB13824190

Can't disable Writing Tools for SwiftUI TextField
I'm trying to disable Writing Tools for a specific TextField using .writingToolsBehavior(.disabled), but when running the app on my iPhone 16 Pro with Apple Intelligence enabled, I can still use Writing Tools on the text box. I also see no difference with .writingToolsBehavior(.limited). Is there something I'm doing wrong or is this a bug? Sample code below: import SwiftUI struct ContentView: View { @State var text = "" var body: some View { VStack { TextField("Enter Text", text: $text) .writingToolsBehavior(.disabled) } .padding() } } #Preview { ContentView() }
