CloudKit and SwiftData not syncing on MacOS
I have a simple app that uses SwiftUI and SwiftData to maintain a database. The app runs on multiple iPhones and iPads and correctly synchronises across those platforms. So I am correct setting Background Modes and Remote Notifications. I have also correctly setup my Model Configuration and ModelContainer (Otherwise I would expect syncing to fail completely). The problem arises when I run on a Mac (M1 or M3) either using Mac Designed for iPad or Mac Catalyst. This can be debugging in Xcode or running the built app. Then the app does not reflect changes made in the iPhone or iPad apps unless I follow a specific sequence. Leave the app, (e.g click on a Finder window), then come back to the app (i.e click on the app again). Now the app will show the changes made on the iPhone/iPad. It looks like the app on the Mac is not processing remote notifications when in the background - it only performs them when the app has just become active. It also looks like the Mac is not performing these sync operations when the app is active. I have tried waiting 30 minutes and still the sync doesn't happen unless I leave the app and come back to it. I am using the same development CloudKit container in all cases

Get update token from the OS when the Live Activity is started from the backend, without the user explicitly providing "Allow" or "Always Allow" consent from the lock screen
We are currently using Live Activities in our app and supporting both of the following use cases: Starting a Live Activity directly from the app using ActivityKit APIs. Starting a Live Activity from the backend using the start token. In the first case (initiated from the app), the OS generates an update token, and we are able to continuously update the Live Activity via our backend—even if the user has not explicitly provided "Allow" or "Always Allow" consent from the lock screen. This works as expected. In the second case (initiated from the backend), if the user does provide consent ("Allow" or "Always Allow") from the lock screen, we receive the update token and can continue updating the Live Activity. However, if the user does not provide consent, the OS does not provide the update token, and we are unable to send further updates. Question: Is it possible to receive the update token from the OS when the Live Activity is started from the backend, without the user explicitly providing "Allow" or "Always Allow" consent from the lock screen? We would appreciate any clarification or official documentation related to this behavior. Thank you!

PKPassLibrary.requestAutomaticPassPresentationSuppression Behavior
We are implementing a feature that uses PKPassLibrary.requestAutomaticPassPresentationSuppression to prevent the Wallet from appearing when unlocking a lock. We have already completed the approval process for the entitlement to enable Pass Presentation Suppression. In most cases, our code snippet works as expected, and the result is .success. However, we are also encountering other results, such as .denied, .alreadyPresenting, and .cancelled or .notSupported, which cause the Wallet to appear for users. Here's the code snippet we're using: PKPassLibrary.requestAutomaticPassPresentationSuppression { result in logger.log( .info, "PKPassLibrary suppression result: \(result.description)", LogContext.homeFeature ) } I would appreciate clarification on the following points: What's the meaning of each result type (.denied, .alreadyPresenting, .cancelled, .notSupported) beyond what is mentioned in the documentation? The documentation here does not provide additional details. What is the recommended handling for these specific result states? Should we be taking different actions or retries based on each case? Thank you very much for your help. Best, Ramiro.

SwiftData and CloudKit
Recently I've been working on a demo project called iLibrary. The main goal was to learn more about CloudKit and SwiftData. After a while I noticed that there were some hangs/freezes when running the app in debug mode. I first tried this with Xcode 15.4 and iOS 17.5. Here the hang only appears at the beginning, but only for a few seconds. But when I exit debug mode, there are no more hangs. With Xcode 16 beta 4 and iOS 18 it looks completely different. In this case, the hangs and freezes are always present, whether in debug mode or not. And it's not just at the beginning, it's throughout the app. I'm aware that this is still a beta, but I still find this weird. And when I profile this I see that the main thread gets quite overloaded. Interestingly, my app doesn't have that many operations going on. So I guess something with the sync of SwiftData or my CloudKitManger where I fetch some records from the public database is not running fine. Lastly, I wanted to delete the iCloud app data. So I went to Settings and tried to delete it, but it didn't work. Is this normal? Does anyone have any idea what this could be? Or has anyone encountered this problem as well? I'd appreciate any support. My project: https://github.com/romanindermuehle/iLibrary

AppShortcutsProvider limitedAvailability in result builder crash
My team is preparing for iOS 18, and wanted to add intents using assistant schemas that are iOS 18 and above restricted. We noticed that the result builder for AppShortcuts added support for limitedAvailabilityCondition from iOS 17.4 so we marked the whole struct as available from it. The app compiles but writing a check like below inside appShortcuts property a crash will happen in iOS 17.5 runtime. (Removing the #available) is solving this problem. if #available(iOS 18, *) { AppShortcut( intent: SearchDonut(), phrases: [ "Search for a donut in \(.applicationName)" ], shortTitle: "search", systemImageName: "magnifyingglass" ) } We tried out putting the os check above and returning shortcuts in arrays and that both compiles and runs but then AppShortcuts.strings sends warnings that the phrases are not used (This phrase is not used in any App Shortcut or as a Negative Phrase.) because the script that extracts the phrases somehow fails to perform when shortcuts are written like below: static var appShortcuts: [AppShortcut] { if #available(iOS 18.0, *) { return [ AppShortcut( intent: CreateDonutIntent(), phrases: [ "Create Donut in \(.applicationName)", ], shortTitle: "Create Donut", systemImageName: "pencil" ) ] } else { return [ AppShortcut( intent: CreateDonutIntent(), phrases: [ "Create Donut in \(.applicationName)", ], shortTitle: "Create Donut", systemImageName: "pencil" ) ] } } This is very problematic because we can't test out on TF with external users new intents dedicated for iOS 18. We filed a radar under FB15010828

How to determine TX region when using Declared Age Range (SB2420 compliance)
Hello, I’m working on implementing SB2420 compliance using the Declared Age Range framework. While referring to the documentation at https://developer.apple.com/documentation/declaredagerange, I couldn’t find details on how the TX region (transaction region or territory) is determined when using Declared Age Range. Specifically, I’d like to confirm the following points: How does the system determine the TX region when the user’s declared age range is retrieved? Is it based on the App Store region, the device locale, or the user’s Apple ID country? If the app’s backend needs to verify or log the TX region, is there a way to obtain or infer it from the API response or receipt data? Is there any difference in TX region determination between Sandbox and Production environments? If anyone has experience implementing Declared Age Range (SB2420) and handling region determination, I’d appreciate your insights or best practices. Thank you.

CloudKit: how to handle CKError partialFailure when using NSPersistentCloudKitContainer?
I'm using NSPersistentCloudKitContainer with Core Data and I receive errors because my iCloud space is full. The errors printed are the following: <CKError 0x280df8e40: "Quota Exceeded" (25/2035); server message = "Quota exceeded"; op = 61846C533467A5DF; uuid = 6A144513-033F-42C2-9E27-693548EF2150; Retry after 342.0 seconds>. I want to inform the user about this issue, but I can't find a way to access the details of the error. I'm listening to NSPersistentCloudKitContainer.eventChangedNotification, I receive a error of type .partialFailure. But when I want to access the underlying errors, the partialErrorsByItemID property on the error is nil. How can I access this Quota Exceeded error? import Foundation import CloudKit import Combine import CoreData class SyncMonitor { fileprivate var subscriptions = Set<AnyCancellable>() init() { NotificationCenter.default.publisher(for: NSPersistentCloudKitContainer.eventChangedNotification) .sink { notification in if let cloudEvent = notification.userInfo?[NSPersistentCloudKitContainer.eventNotificationUserInfoKey] as? NSPersistentCloudKitContainer.Event { guard let ckerror = cloudEvent.error as? CKError else { return } print("Error: \(ckerror.localizedDescription)") if ckerror.code == .partialFailure { guard let errors = ckerror.partialErrorsByItemID else { return } for (_, error) in errors { if let currentError = error as? CKError { print(currentError.localizedDescription) } } } } } // end of sink .store(in: &subscriptions) } }

watchOS: AppIntents.IntentRecommendation description ignored when applying a .watchface
When we use AppIntents to configure WidgetKit complications, the description we provide in IntentRecommendation is ignored after applying a .watchface file that includes those intent configurations. In the Watch app, under Complications, the labels shown next to each slot do not match the actual complications on the face—they appear to be the first strings returned by recommendations() rather than the selected intent configuration. Steps to Reproduce Create an AppIntent used by a WidgetKit complication (e.g., .accessoryRectangular). Provide multiple intent recommendations with distinct descriptions: struct SampleIntent: AppIntent { static var title: LocalizedStringResource = "Sample" static var description = IntentDescription("Sample data") @Parameter(title: "Mode") var mode: String static func recommendations() -> [IntentRecommendation<Self>] { [ .init(intent: .init(mode: "A"), description: "Complication A"), .init(intent: .init(mode: "B"), description: "Complication B"), .init(intent: .init(mode: "C"), description: "Complication C") ] } func perform() async throws -> some IntentResult { .result() } } Add two of these complications to a Modular Duo face (or any face that supports multiple slots), each with different intent configurations (e.g., A in one slot, B in another). Export/share the face to a .watchface file and apply it on another device. Open the Watch app → the chosen face → Complications. Expected Each slot’s label in Complications reflects the specific intent configuration on the face (e.g., “Complication A”, “Complication B”), matching what the complication actually renders. Actual The labels under Complications do not match the visible complications. Instead, the strings shown look like the first N items from recommendations(), regardless of which configurations are used in each slot. Notes The complications themselves render correctly on-watch; the issue is the names/labels displayed in the Watch app UI after applying a .watchface. Filed Feedback: FB20915258

Private database: failed to access iCloud data please signin again.
When I logged into my cloudkit console to inspect the database for some debugging work I couldn't access the private database. It keeps saying "failed to access iCloud data, please signi n again". No matter how many times I sign in again, whether with password or passwordless key it keeps saying the same thing. It says that message when I click on Public database, and private and shared databases are below it. I only noticed this a couple of days ago. It's done this in the past, but I eventually got back into the database but I don't know what changed to make it work.

Crashes because main actor isolated closures are called on a background thread with `DispatchGroup.notify`, but no compiler warnings
Hello! We are in the progress of migrating a large Swift 5.10 legacy code base over to use Swift 6.0 with Strict Concurrency checking. We have already stumbled across a few weird edge cases where the "guaranteed" @MainActor isolation is violated (such as with @objc #selector methods used with NotificationCenter). However, we recently found a new scenario where our app crashes accessing main actor isolated state on a background thread, and it was surprising that the compiler couldn't warn us. Minimal reproducible example: class ViewController: UIViewController { var isolatedStateString = "Some main actor isolated state" override func viewDidLoad() { exampleMethod() } /// Note: A `@MainActor` isolated method in a `@MainActor` isolated class. func exampleMethod() { testAsyncMethod() { [weak self] in // !!! Crash !!! MainActor.assertIsolated() // This callback inherits @MainActor from the class definition, but it is called on a background thread. // It is an error to mutate main actor isolated state off the main thread... self?.isolatedStateString = "Let me mutate my isolated state" } } func testAsyncMethod(completionHandler: (@escaping () -> Void)) { let group = DispatchGroup() let queue = DispatchQueue.global() // The compiler is totally fine with calling this on a background thread. group.notify(queue: queue) { completionHandler() } // The below code at least gives us a compiler warning to add `@Sendable` to our closure argument, which is helpful. // DispatchQueue.global().async { // completionHandler() // } } } The problem: In the above code, the completionHandler implementation inherits main actor isolation from the UIViewController class. However, when we call exampleMethod(), we crash because the completionHandler is called on a background thread via the DispatchGroup.notify(queue:). If were to instead use DispatchQueue.global().async (snippet at the bottom of the sample), the compiler helpfully warns us that completionHandler must be Sendable. Unfortunately, DispatchGroup's notify gives us no such compiler warnings. Thus, we crash at runtime. So my questions are: Why can't the compiler warn us about a potential problem with DispatchGroup().notify(queue:) like it can with DispatchQueue.global().async? How can we address this problem in a holistic way in our app, as it's a very simple mistake to make (with very bad consequences) while we migrate off GCD? I'm sure the broader answer here is "don't mix GCD and Concurrency", but unfortunately that's a little unavoidable as we migrate our large legacy code base! 🙂

Transactions Finish does not work on iOS 26 beta3
On iOS 26 beta 3, after a user purchases an item, initiating a second order for the same product fails to process payment. The system returns the same transaction ID and displays an interface message stating: "You've already purchased this In-App Purchase. It will be restored for free."​​ ​​I’ve tested this – not only did the legacy StoreKit finishTransaction method fail to work, but StoreKit2 finish method also malfunctioned.​​ ​​When will Apple fix this issue? If unresolved, it will prevent a large number of users from making purchases normally, leading to disastrous consequences.​

Provisional Permission is not working as expected in iOS 16
We recently developed the provisional permission for our app, but we have noticed that is not working as expected in iOS 16 (We have tested only there). Currently we request the permissions like this: UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound, .provisional]) { [weak self] _, _ in // here we register for pushes in case authorizationStatus is provisional or authorised } What happens is we do get the 1st notification with the keep CTA - once tapped we see that there pops an action: "Deliver Immediately", but even though the user selects that, we still see under setting the pushes are marked as "Deliver Quietly". In addition to this the sound and bage still stay as toggled off - and the lock screen and banner as well stay off. Basically, nothing changes after the user selects "Deliver Immediately"

How is Record Zone Sharing done?
My use case is the following: Every user of my app can create as an owner a set of items.  These items are private until the owner invites other users to share all of them as participant. The participants can modify the shared items and/or add other items. So, sharing is not done related to individual items, but to all items of an owner. I want to use CoreData & CloudKit to have local copies of private and shared items. To my understanding, CoreData & CloudKit puts all mirrored items in a special zone „com.apple.coredata.cloudkit.zone“. So, this zone should be shared, i.e. all items in it. In the video it is said that NSPersistentCloudKitContainer uses Record Zone Sharing optionally in contrast to hierarchically record sharing using a root record. But how is this done? Maybe I can declare zone „com.apple.coredata.cloudkit.zone“ as a shared zone?

AppStore.sync() not restoring purchases
On an app that was using the old API for In-App Purchases (StoreKit 1). The app is already published on the App Store. The purchase is non-consumable. While trying to migrate to StoreKit 2, I'm unable to restore purchases. Specifically displaying and purchasing products works as expected, but when deleting and reinstalling the app, and then trying to restore purchases I can't do it. I'm trying to restore them using the new APIs but it doesn't seem to be working. What I have tried so far: I'm listening for transaction updates during the whole lifetime of the app, with: Task.detached { for await result in Transaction.updates { if case let .verified(safe) = result { } } } I have a button that calls this method, but other than prompting to log in again with the Apple ID it doesn't seem to have any effect at all: try? await AppStore.sync() This doesn't return any item for await result in Transaction.currentEntitlements { if case let .verified(transaction) = result { } } This doesn't return any item for await result in Transaction.all { if case let .verified(transaction) = result { } } As mentioned before I'm trying this after purchasing the item and deleting the app. So I'm sure it should be able to restore the purchase. Am trying this both with a Configuration.storekit file on the simulator, and without it on a real device, in the Sandbox Environment. Has anyone being able to restore purchases using StoreKit 2? PD: I already filed a feedback report on Feedback Assistant, but so far the only thing that they have replied is: Because StoreKit Testing in Xcode is a local environment, and the data is tied to the app, when you delete the app you're also deleting all the transaction data for that app in the Xcode environment. The code snippets provided are correct usage of the API. So yes, using a Configuration.storekit file won't work on restoring purchases, but if I can't restore them on the Sandbox Environment I'm afraid that this won't work once released, leaving my users totally unable to restore what they have already purchased.

How to Set Up Deferred Deep Linking
I have universal links configured for my iOS app which work as expected when the app is installed. When the app is not installed the universal link will go to the browser as expected. What I want to do is redirect to the app store, allow the user to install the app, then redirect them to the initial universal link. Redirecting them to the app store isn't the hard part I can achieve that from the webpage, however I don't know how to save a reference to that initial link to redirect them once they instal the app. What I want the flow to be for a user who doesn't have the app is: visit a universal link (example.com/UUID) redirect to the app store and install the app open the app and redirect to example.com/UUID I've seen some ways people are doing this with the clipboard but I don't love that solution, I also don't want to use a 3rd party service if I can avoid it - how are the 3rd party services making this happen?

JWT Token Errors
I have an app using weatherkit and its currently live and up on the app store, recently I had some users report to me that they had been receiving errors loading weather data, I had error handling built in and it reported an issue with apples authentication server Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" I have not come across this during the development lifecycle of my project, there where no codebase changes, it just stopped functioning. The app entitlements are valid and correct, Weatherkit is enabled in both xcode and across my Certs, identifiers and profiles. I was not experiencing this issue until I reinstalled the app from the app store completly by first removing it and then re-installing fresh. Hard reboots do not help and I do not want to start suggesting to my users to factory reset their devices. We are using WeatherKit in both our main app and widget, relying entirely on Apple’s framework for authentication and token management. We do not generate or inject our own JWT tokens; all token handling is managed by WeatherKit. We have implemented a debug menu with the following actions: Clear WeatherKit JWT tokens from the keychain Clear all related UserDefaults key Clear all app group data and all UserDefaults. Perform a “nuclear” cache clear (removes all app data, keychain, and cached files). We log all WeatherKit fetch attempts and failures, including authentication errors, both in the app and widget and get nothing but code 2. We have attempted all of the above steps, but continue to experience issues with WeatherKit JWT authentication We would appreciate any guidance or insight into what else could be causing persistent WeatherKit JWT/authentication issues, or if there are any additional steps we should try. P.S. - Tested and experiencing the same issues on an iPhone 15 Pro Max and iPhone 15 The Pro Max is on the iOS 26 Beta // and the 15 is on the latest iOS 18

New push notifications for widgets seem too limited for actual production-level apps
I was very excited to see the addition of push notifications for widgets. However upon further inspection, the way it is implemented seems too limiting for real life apps. I have an app for time tracking with my own backend. The app syncs with my backend in the main executable (main target). My widgets are more lightweight as they only access data in the shared app container, but they don't perform sync with the server directly to avoid race conditions with the main app. I was under the impression that the general direction of the platform is to be doing most things in the main app target (also App Intents work that way for the most part), so the fact that the WidgetPushHandler just calls the widget's method to reload the timeline is very unfortunate. In an ideal scenario I also need the main app to be 'woken up' to perform the sync with the server, and once that's done I'd update the widget's timeline and where I would just read data from the shared app container. So, my questions are: What is the recommended way of updating the widgets when this push notification arrives in the case that the main app target needs to perform the sync first? Is there any way how to detect that the method func timeline(for configuration: InteractiveTrackingWidgetConfigurationAppIntent, in context: Context) was called as a result of the push notification being received? Can I somehow schedule a background task from the widget's reloadTimeline() function? How can I get the push token later, in case that I don't save it right away the first time the WidgetPushHandler's pushTokenDidChange() is called? Thank you for your work on this and hopefully for your answers. FB19356256

iOS 26.2 (23C55): DeviceActivity eventDidReachThreshold fires with 0 Screen Time minutes
On iOS 26.2 (23C55), DeviceActivityMonitor.eventDidReachThreshold fires intermittently for a daily schedule (00:00–23:59) even when iOS Screen Time shows 0 minutes for the selected apps that day. This causes premature shielding via ManagedSettings. Environment: iPhone 13 Pro Max, iOS 26.2 (23C55). Event selection: 2 apps. Threshold: 30 minutes. Multiple TestFlight users report the same behavior across various app selections and thresholds. Intermittent (~50% of days); sometimes multiple days in a row. Not observed in testing prior to iOS 26.2. Evidence: sysdiagnose + Screen Time screenshots (with 0 screen time on selected apps) + unified logs show UsageTrackingAgent notifying the extension that “unproductive from activity daily reached its threshold,” followed immediately by ManagedSettings shield being applied (extension reacting to the callback). Filed Feedback Assistant: FB21450954. Questions: Are others seeing this on 26.2? Does it correlate with restarting monitoring at interval boundaries or includesPastActivity settings?
