Database disk image is malformed in Call Blocking
I have an app developed by using the Callkit/Call-Blocking and received feedback from individual users, when using [cxcalldirectorymanager reloadextensionwithidentifier] to write call blocking data, it returned error code 11 with the following contents: errorCode: 11 errorDomain: com.apple.callkit.database.sqlite errorDescription: sqlite3_step for query 'DELETE FROM PhoneNumberBlockingEntry WHERE extension_id =?' returned 11 (11) errorMessage 'database disk image is malformed' I want to know the reasons for this error and how to solve it,Thanks!

[iOS 18 Beta 4] DeviceActivityMonitor extension is more likely to deadlock
Hi there, My app uses all the Screen Time API's with individual FamilyControls authorization. I've been using the API's for over 2 years (since they came out). In iOS 18 Beta (maybe started in Beta 3?), I've been experiencing random issues. I tracked it down to where it seems like DeviceActivityMonitor extension is more likely to deadlock in iOS 18. To reproduce: when DeviceActivityMonitorExtension.intervalDidEnd gets called, IF you call DeviceActivityCenter.startMonitoring for that SAME DeviceActivityName from the DeviceActivityMonitorExtension , the startMonitoring call deadlocks (if I pause debugger, it does not advance past DeviceActivityCenter.startMonitoring). The bug is reported in FB14664238. It also contains a sample project where you can reproduce this. I also note in the comment section that this is not the only way to encounter this problem. My application code (which is a lot more complicated) seems to deadlock on calling DeviceActivityCenter.activities. As a result, there seems to be an "overall trend" where, due to some changes, DeviceActivityMonitor extension is more likely to deadlock. The steps are not reproducible on iOS 17.6. This is built using Xcode 17.4. Thank you! 🙏

Live Caller ID on iOS does not work - client requests not reaching backend
I'm reaching out to see if anyone else is experiencing issues with the Live Caller ID feature on iOS. We recently encountered a problem where the feature stopped working entirely. Here's a brief overview of the situation: We were monitoring test traffic on our backend and noticed everything came to a halt around 1:00 AM UTC on November 15th. After this time, any attempts to reach our backend through calls failed completely. I tested this across multiple devices running iOS 18.2 and iOS 18.0. I used both TestFlight builds and development builds via Xcode, which should communicate directly with our backend. I experienced the problem on our main application as well as a dedicated test app. To troubleshoot further, I even set up a local server on localhost and tried directing requests there, but the requests did not reach the local server when a call was received. Further debugging in Console.app revealed the following error: identity request returned error: Error Domain=com.apple.CipherML Code=400 "Error Domain=com.apple.CipherML Code=401 "Unable to request data by keywords batch: failed to fetch token issuer directory" However, when I manually tried to hit our server endpoint using curl, the request successfully reached the server: curl https://our_server/something hb_method=GET hb_uri=/something [Hummingbird] Request -- log on backend This suggests that while our backend is responsive, the requests from the iOS client side are simply not being initiated.

How to debug Quick Look Preview Extension
When I launch the Quick Look Preview Extension target in Xcode, an app called Quick Look Simulator opens with an almost empty window: Online I read that the Terminal command qlmanage allows to test Quick Look plugins (which I think were an older format for creating Quick Look extensions), but running qlmanage -p /path/to/previewed/file -c public.text -g /path/to/QuickLookPreviewExtension.appex (where QuickLookPreviewExtension.appex is generated by the Xcode build and is located in the DerivedData folder) gives an error Can't get generator at QuickLookPreviewExtension.appex How can I debug a Quick Look Preview Extension?

Contacts Provider Extension not removed from Contacts list after app uninstall on iOS 26
Hi, I’ve built an app that includes a Contacts Provider Extension (CPE). On iOS 18, I observed the expected behavior — when the main app is uninstalled, the corresponding CPE entry is also removed from the Contacts list. However, on iOS 26, this no longer happens. After uninstalling the app, the CPE remains visible and active in the Contacts list, even though the app is gone.

Permission error occurs when I use setDefaultApplication(at:toOpen:completion:)
I'd like to set my macOS app written in Swift as default app when opening .mp4 file. I think I can do it with setDefaultApplication(at:toOpen:completion:). https://developer.apple.com/documentation/appkit/nsworkspace/3753002-setdefaultapplication However, permission error occurs when I use it. The error is: Error Domain=NSCocoaErrorDomain Code=256 "The file couldn’t be opened." UserInfo={NSUnderlyingError=0x6000031d0150 {Error Domain=NSOSStatusErrorDomain Code=-54 "permErr: permissions error (on file open)"}} I tried to give my app full-disk access, but it didn't work. I also tried to use setDefaultApplication(at:toOpenFileAt:completion:), then it works with no error, but it effects on only one file. What I want to do is to set my app as default app of all .mp4 files. How do I achieve this? My code is like below: let bundleUrl = Bundle.main.bundleURL NSWorkspace.shared.setDefaultApplication(at: bundleUrl, toOpen: .mpeg4Movie) { error in print(error) } Thank you.

Testing Age Assurance in Sandbox Failed
According to Apple's documentation at https://developer.apple.com/documentation/storekit/testing-age-assurance-in-sandbox?language=objc, the testing steps and expected responses are outlined as follows: ​Test app consent revocation​ To test the notification when a parent or guardian revokes access to your app on behalf of their child, follow these steps: Start with a Sandbox account. From the Age Assurance settings, tap ​Revoke App Consent. Enter your app’s Bundle ID (for example, com.example.bundle). Tap ​Revoke Consent​ to simulate the revocation. Confirm that the system displays ​​“Notification Triggered”​​ with the message ​​“A notification will be sent to the developer server soon.”​ I followed the steps exactly as described above, but during the fifth step, instead of seeing the prompt ​​"A notification will be sent to the developer server soon,"​​ a pop-up dialog with only a confirmation button appeared. After clicking it, there was no further response, and our server did not receive any notification (neither from the Sandbox nor the Production environment).

Refresh Widget doesn't work from background push notification.
As stated in other posts like: https://developer.apple.com/forums/thread/734488 https://developer.apple.com/forums/thread/652946?answerId=823555022#823555022 Even though the recommended way from Apple documentation is to use push notifications to reload widgets timelines calling WidgetCenter.shared.reloadAllTimelines(), it is unreliable and I couldn't find a pattern of why it works 10% of times and not the other 90%. While the debugger is connected to the App it always works though. My widget needs to reflect updated information otherwise it becomes useless since it display smart home devices states such as the Apple Home widget does as well.

Is testing of Age Range API available in xcode simulator?
From https://developer.apple.com/forums/thread/803945?answerId=862153022#862153022, the testing of Age Range API was not available through xcode simulator back in Oct 2025. Is this available now? In particular: Is requestAgeRange testing available through simulator? Is requestAgeRange testing with sandbox account available through simulator? Is isEligibleForAgeFeatures available through simulator? Is isEligibleForAgeFeatures testing with sandbox account available through simulator? If the answer is "yes" to any of the above, which version of the xcode and ios version should I use? So far I didn't get any of the above working on the simulator, and I can't find any documentation on the answers above. Thank you!

The problem is i got the popup the first time i opened the application and decided to share, but after that i always get the following error: DeclaredAgeRange.AgeRangeService.Error.notAvailable I tried testing with different bundle id and different sandbox test account but still it doesn't work. How can i test the cases without erasing the device ?

Universal Link Not Working – Apple Request Blocked by Firewall Due to Geographic Restriction
Hello, I’m encountering an issue with Universal Links in my iOS app. After some investigation, I found that the root cause seems to be that Apple’s request through there CDN server to access the .well-known/apple-app-site-association file is blocked by our firewall, which enforces geographic access restrictions as part of our security policy. Because of this restriction, Apple’s validation or link verification requests are being denied, and the Universal Links are not working as expected. I’d like to get some guidance from the community or Apple engineers on the following: 1. Does Apple provide an official list of IP ranges or domains that need to be allowed through the firewall for Universal Link validation? 2. Are there alternative methods to handle Universal Link verification in environments with geographic restrictions? 3. Would whitelisting specific Apple services or endpoints be a recommended or safe solution? Any input or recommendations would be greatly appreciated. Environment Details: • iOS app using Universal Links • Server protected by a firewall with regional restrictions • AASA file hosted correctly and accessible via browser Thanks in advance for your help and insights.

v2 Weatherkit REST API documentation release date
Hi. The WWDC video of the v2 weatherkit api showed some examples for the REST API. However, they were very limited. The documentation for the REST API is currently for the v1 weatherkit API. When will the documentation for the v2 API be released? There are some new features of the v2 that I would really like to use, but I can't without knowing the new v2 REST API specifications. Any guidance would be much appreciated. Thanks!

CallKit Call Directory database corruption (sqlite Code 11)
Hi everyone, I’ve filed a Feedback report (FB20986470) for a serious issue affecting the Call Directory database when add phone numbers for call blocking. When adding blocking numbers to a Call Directory extension, the system’s CallKit database (/private/var/mobile/Library/CallDirectory/CallDirectory.db) becomes corrupted. The reload call (reloadExtensionWithIdentifier) fails with error code 11 when the system tries to insert blocking entries, and the Console app on macOS shows the following errors: database corruption page 2265525 of /private/var/mobile/Library/CallDirectory/CallDirectory.db at line 81343 of [f0ca7bba1c] database corruption at line 79387 of [f0ca7bba1c] Error Domain=com.apple.callkit.database.sqlite Code=11 "sqlite3_step for query 'INSERT INTO PhoneNumberBlockingEntry (extension_id, phone_number_id) VALUES (?, (SELECT id FROM PhoneNumber WHERE (number = ?))), (?, (SELECT id FROM PhoneNumber WHERE (number = ?))),...)'" After this happens, CallKit becomes fully corrupted on the device and no further numbers can be added, even after: Disabling and re-enabling the extension Restarting the device (either force or soft restart) Reinstalling the app Waiting for a couple of minutes after this issue happens (that CallKit could possibly self-recovered) I also tested other call-blocking apps, and they all fail with the same error. The only thing that recovers the system is a full “Reset All Settings.” This issue has been reported by many users of my app, across multiple iOS versions and devices. Similar related issue reported by another developer: https://developer.apple.com/forums/thread/806129 Steps to Reproduce: Enable the Call Directory extension from a call-blocking app. Add and reload blocking numbers (a few thousand entries). Perform multiple reloads between additions. Check the Console, the corruption errors appear. From this point, all insert attempts fail system-wide. Expected Result: Entries should be inserted successfully, or the system should self-recover without persistent corruption. Actual Result: sqlite3_step fails with Code=11, and the Call Directory database remains corrupted until the user resets all settings. Additional Notes: All numbers are sorted and deduplicated before insertion. Happens intermittently after multiple reloads. The system log always shows internal database failure. Environment: Device: iPhone 16 Plus iOS 18.2 Beta (23C5027f) Xcode 16.1 (17B55) Attachments (included in Feedback FB20986470): sysdiagnose captured immediately after the failure (with Phone app General Profile) It seems like a system-level corruption affecting all Call Directory extensions once it occurs.

AppIntents Parameter requestValue not working in iOS 18 when parameter is not in parameterSummary
In iOS 18, the requestValue method no longer works when the parameter it is called on is not included in the parameterSummary of an AppIntent. This issue causes the app to fail to present a prompt for the user to select a value, resulting in an error with the message: Domain=NSCocoaErrorDomain Code=4099 "The connection from pid 40685 on anonymousListener or serviceListener was interrupted, but the message was sent over an additional proxy and therefore this proxy has become invalid." Steps to Reproduce: Create a simple AppIntent with the following code: import AppIntents struct Intent: AppIntent { static let title: LocalizedStringResource = "Intent" static var parameterSummary: some ParameterSummary { Summary("Test \(\.$category)") {} } @Parameter(title: "Category") private var category: CategoryEntity? @Parameter(title: "Hidden Category") private var hidden: CategoryEntity? @MainActor func perform() async throws -> some ReturnsValue<CategoryEntity?> { var result: CategoryEntity? do { result = try await $hidden.requestValue("Select category") // Doesn't work since iOS 18 as $hidden is not set in parameterSummary } catch { print("\(error)") } return .result(value: result) } } Run the code on a device with iOS 18. Observe that the requestValue method fails to present the selection prompt and instead throws an error. Expected Results: The app should successfully present a prompt for the user to select a value for the hidden parameter using requestValue, even if the parameter is not included in the parameterSummary. Actual Results: The app fails to present the selection prompt and throws an error, making it impossible to use requestValue for parameters not included in parameterSummary. Version/Build: iOS 18.0 Configuration: Tested on various devices running iOS 18. Is there a change in the API that I might have missed?

How to open up an extension point to a third-party app (extension)
According to the documentation, using Scope(restriction: .none) can expose the extension point to third-party app extensions. Below is my implementation, which ultimately results in an error. Code for declaring the extension point: @available(iOS 26.0, *) extension AppExtensionPoint { @Definition static var priceExtension: AppExtensionPoint { Name("priceExtension") UserInterface(false) Scope(restriction: .none) } } Code for locating the extension point: monitor = try await AppExtensionPoint.Monitor(appExtensionPoint: .priceExtension) When executing the code to locate the extension point, the following error occurs: However, in practice, I found that declaring the extension point in this way results in an error when trying to locate it: Error Domain=com.apple.extensionKit.errorDomain Code=19 "Failed to add observer" UserInfo={NSLocalizedDescription=Failed to add observer}

Question about including all project classes in ofClasses parameter when using NSKeyedUnarchiver.unarchivedObject(ofClasses:from:)
Hello, I have a question about data deserialization using NSKeyedUnarchiver in iOS SDK development. Current Situation: Previously, we were using the NSKeyedUnarchiver.unarchiveObject(with: Data) function We have changed to using the NSKeyedUnarchiver.unarchivedObject(ofClasses:from:) method to deserialize complex objects stored in UserDefaults We need to include all types in the ofClasses parameter, including Swift primitive types as well as various custom classes and structs within the project Questions: Implementation Approach: Is it correct pattern to include all classes defined in the project in the ofClasses array? Is this approach recommended? Runtime Stability: When using this approach, is there a possibility of runtime crashes? Are there any performance issues? Alternative Methods: If the current approach is not the correct pattern, what alternatives should we consider? Current Code Structure: All model classes conform to the NSSecureCoding protocol We use the requiringSecureCoding: true parameter We use a whitelist approach, explicitly listing only allowed classes I would like to know if this structure is appropriate, or if we should consider a different approach. Thank you.

Issue with DeviceActivityMonitor - eventDidReachThreshold Callback Not Triggering Properly
Hello, I'm currently experiencing an issue with the DeviceActivityMonitor extension in my code, specifically with the eventDidReachThreshold callback. I'm hoping to get some insights into why this problem occurs and how to resolve it. Problem: Issue 1: The eventDidReachThreshold callback is not triggering as expected. It appears that the callback is not being invoked when the threshold is reached. Issue 2: After a few seconds, the eventDidReachThreshold callback starts to trigger multiple times. This unexpected behavior is causing problems in my code, as it results in incorrect actions being taken. iOS version: iOS16.7.2 and iOS17.1 Xcode version: 15.0.1 Swift version: 5.9 Here is my code to start the monitoring: func startMonitoring() { var startTime : DateComponents = DateComponents(hour: 0, minute: 0) let endTime : DateComponents = DateComponents(hour: 23, minute: 59) /// Creates the schedule for the activity, specifying the start and end times, and setting it to repeat. let schedule = DeviceActivitySchedule(intervalStart: startTime, intervalEnd: endTime, repeats: true, warningTime: nil) /// Defines the event that should trigger the encouragement. let event = DeviceActivityEvent(applications: socialActivitySelection.applicationTokens, categories: socialActivitySelection.categoryTokens, webDomains: socialActivitySelection.webDomainTokens, threshold: DateComponents(minute: 2)) let events: [DeviceActivityEvent.Name: DeviceActivityEvent] = [.socialScreenTimeEvent : event] do { activityCenter.stopMonitoring([.socialScreenTime]) /// Tries to start monitoring the activity using the specified schedule and events. try activityCenter.startMonitoring(.socialScreenTime, during: schedule, events: events) } catch { /// Prints an error message if the activity could not be started. print("Could not start monitoring: \(error)") } } If there are any known workarounds or potential solutions, please share them. Thank you for your help in resolving this problem.
