Since I updated to iOS 18, CallKit-linked caller not display on screen of CarPlay. CarPlay display only "{App Name} Caller ID". When iOS version was 17.x, CarPlay displayed caller name of CallKit-linked contact. I think CarPlay should perform the same function as iOS 17. Please review it.

Hello, In production, a large number of users experience outgoing call reporting fails with the following error: com.apple.CallKit.error.requesttransaction Code=2 The iOS version doesn't matter, errors are present in v15-26 Details My CXProvider held as a global singleton, so it’s unlikely to be deinited. There is no explicit call to CXProvider.invalidate() in the app. If I manually invalidate the CXProvider, I observe the expected failure when trying to create an outgoing call (com.apple.CallKit.error.requesttransaction error 2). However, If I recreate the CXProvider after the error, outgoing calls are reported correctly. Many users trigger the providerDidReset delegate method (CXProviderDelegate) before this error. According to the documentation, providerDidReset can be called by the system, and we are supposed to end all active calls, but the documentation doesn't suggest recreating the CXProvider. Question Should I recreate CXProvider after providerDidReset and forget about that, or could this error be caused by something else?

I'm using the new AlarmKit framework to schedule and trigger alarms in my Swift app in iOS 26 beta 4 (23A5297i). I'm trying to customize the alarm sound using a sound file embedded in the app bundle or by referencing known system tones. Problem: No matter what I pass to .named("sound-2"), whether a file bundle url, .named("sound-2.caf"), tried .mp3, .caf & .aiff, or a known iOS system sound like .named("Radar") ("Chimes", etc.), the alarm always plays the default system alert tone. There's no error or warning, but the custom or specified sound is silently ignored. sound: .named("sound-2") Question: What is the correct method or approach to play custom sound / music when Alarm Triggers? What .named("...") expects file name, file Path URL or System sound name? Is there any specific audio file length accepted or specific format? Challenge: The alarm functionality feels incomplete without support for custom sounds. A single default alert tone is often not sufficient to wake up users effectively. Hope it will be fixed in the next iOS updates.

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}

We have an application which is written in Swift, which activates Transparent Proxy network extension. We are using Jamf MDM profile for deployment. To avoid the user deleting / disabling the extension from General -> LogIn Items & Extension -> Network Extensions screen, we are using "Non-removable system extensions from UI" attribute under Allowed System Extensions and Teams IDs section. In new Mac OS 26 (Tahoe), user can also enable/disable the extension from General -> LogIn Items & Extension -> Apps tab. The "Non-removable system extensions from UI" attribute set in Jamf MDM profile does not apply to this tab. Same attribute is working for General -> LogIn Items & Extension -> Extensions tab and there the slider is greyed out and Remove option is not available under more menu. Is there any new key/configuration defined to disable the slider from General -> LogIn Items & Extension -> Apps tab? Created https://feedbackassistant.apple.com/feedback/18198031 - FB18198031 feedback assistant ticket as well.

I would like to share an issue observed during app development. When changing Bluetooth settings from the system Settings app without using multitasking, the app does not terminate but instead logs the user out. However, when changing Bluetooth settings while using multitasking, the app terminates completely. In this context, I would like to understand: Whether there is any system behavior that causes the app to refresh or restart when Bluetooth settings are changed And why the app behavior differs in a multitasking environment, particularly in terms of app lifecycle handling Any insights into these behaviors would be greatly appreciated.

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.

Hi All, I’m puzzled by this issue: my app uses WeatherKit to fetch hourly UV-index and temperature forecasts. The same build, running on the latest iOS, succeeds on most devices but consistently fails on a few. Strangely, the paired Apple Watch version retrieves the data without problems. Could WeatherKit be applying per-user throttling? Any insight would be greatly appreciated.

I decode an object with NSKeyedArchiver (SecureCoding): typealias BoolArray = Array<Array<Bool>> let val = decoder.decodeObject(of: NSArray.self, forKey: someKey) as? BoolArray I get the following log: *** -[NSKeyedUnarchiver validateAllowedClass:forKey:] allowed unarchiving safe plist type ''NSNumber' (0x204cdbeb8) [/System/Library/Frameworks/Foundation.framework]' for key 'NS.objects', even though it was not explicitly included in the client allowed classes set: '{( "'NSArray' (0x204cd5598) [/System/Library/Frameworks/CoreFoundation.framework]" )}'. This will be disallowed in the future. I changed by adding NSNumber.self in the list : let val = decoder.decodeObject(of: [NSArray.self, NSNumber.self], forKey: someKey) as? BoolArray No more warning in log. Is there a reason for this ?

Issue with App Clip Card Showing "App Clip unavailable" for DIGI LIVE App In my DIGI LIVE application, I have an App Clip configured for iOS 17.6+ (the file exceeds the 15 MB limit), and I have made all the necessary preparations for the App Clip to work correctly. However, the App Clip card constantly displays an "App Clip unavailable" error for various users (depending on their system language). The URL associated with the App Clip invocation is: https://ar.digi-live.de The AASA file is located at /.well-known/apple-app-site-association and contains the required fields for the App Clip: { "applinks": { "details": [ { "appIDs": ["N9QR6LF765.de.digilive.app"], "components":[ { "#": "no_universal_links", "exclude": true, "comment": "Matches any URL whose fragment equals no_universal_links and instructs the system not to open it as a universal link" }, { "/": "*", "comment": "Matches any URL like ar.digi-live.de" } ] } ] }, "appclips": { "apps": ["N9QR6LF765.de.digilive.app.Clip"] } } If I use the default App Clip link (https://appclip.apple.com/id?p=de.digilive.app.Clip) to launch it, the "App Clip unavailable" error no longer appears. But if I delete the App Clip from the settings, the error comes back, and it can only be launched again using the default link. It feels like the problem is with the App Clip loading at the moment the App Clip card is triggered — it simply fails to load. Video https://storage.yandexcloud.net/mmrs/files/digilive/IMG_2259.mp4

How to programmatically check if ApplicationToken or ActivityCategoryToken is expired in FamilyActivityPicker? I'm building a Screen Time-based parental control app using FamilyControls and ManagedSettings. We use FamilyActivityPicker to allow the user to select apps and categories to restrict, and we apply the shield using: store.shield.applications = .specific(selection.applicationTokens) store.shield.applicationCategories = .specific(selection.categoryTokens) Sometimes, we observe that the shield silently fails to apply — no error is thrown, but the restrictions aren't enforced. I suspect this may be due to expired or invalid tokens, possibly if the app was removed or the selection became stale. My Questions: Can ApplicationToken or ActivityCategoryToken expire or become invalid over time? If yes, is there a supported or recommended way to detect whether a token is still valid before applying it to the shield? Is comparing the current shield values (store.shield.applications and store.shield.applicationCategories) after applying them a reliable validation method? What's the best practice to handle expired tokens (e.g. re-prompt the FamilyActivityPicker, or show a fallback)? What Is the Expiration Duration of Tokens from FamilyActivityPicker? Any guidance or insight from the Screen Time/FamilyControls team would be greatly appreciated! Thank you!

Hello, We are using a Message Filter Extension (ILMessageFilterExtension) to classify SMS/iMessage content (junk vs allow) in our app. After testing on iOS 26.1, we want to confirm whether there are any behavioral, performance, or API-level changes that impact message filtering, such as: Changes in how often the filter extension is invoked Differences in classification accuracy or system overrides New privacy, entitlement, or permission-related restrictions Execution time limits or memory constraints Any changes specific to iMessage vs SMS filtering We did not find any explicit mention of Message Filter Extensions in the iOS 26.1 release notes and would like to confirm whether the existing behavior from previous iOS versions remains unchanged. Has Apple introduced any known or undocumented changes in iOS 26.1 that developers should be aware of when supporting Message Filter Extensions? Sometime I also found unpredictable behaviour on iOS version 18.5 or below, like sometime it works but sometimes starts working. Thanks in advance for any guidance.

Is there a way to enumerate all files within a folder of an asset pack or just all files in general? My application is using the Apple demo code to load a file from an Apple hosted asset pack: let descriptor = try AssetPackManager.shared.descriptor(for: "NAV/NavData.db3") defer { try descriptor.close() } if let path = path(for: descriptor) { self.database = try Database(path: path) } As my "Navigation Data" is updated each month with an updated asset pack I would like to have the name of the .db3 file reflect the current data cycle (e.g. NAV2601.db3, NAV2602.db3, ...) Ideally I would like to iterate over all files within the NAV folder of the current asset pack and pick the most recent one. Unfortunately, neither the AssetPackManager nor the AssetPack object seem to include an API for this. It would be cool to have something like: let files = try AssetPackManager.shared.files(for: "NAV/") for file in files { //Check and load }

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.

There are many units which are inverse of standard units, e.g. wave period vs Hz, pace vs speed, Siemens vs Ohms, ... Dimension can be subclassed to create the custom units. How to extend Measurement.converted( to: )? I was looking at somehow using UnitConverter and subclass to something like UnitConverterInverse. Thoughts?

As discussed and acknowledged here, there is a known bug with the FamilyActivityPicker. When a user expands a category that contains enough tokens to exceed the 50mb memory limit, the FamilyActivityPicker crashes. This happens quite frequently for heavy Safari users. An apple engineer mentioned on this thread that WebDomains shown in the picker are present based on the last 30 days of usage data as surfaced by WebKit. Is there any way a user can clear these WebDomains? Either programatically through our app or any other process we can guide them to as a workaround while this issue is getting fixed?

Our users report frequent crashes with the FamilyActivityPicker. Since this is a screen controlled by Apple, I'm assuming that there's nothing I can do to prevent these crashes. I'm wondering, though, if there's any way to gracefully handle these crashes? When this happens, the following is printed to the console: [com.apple.FamilyControls.ActivityPickerExtension(1121)] Connection to plugin invalidated while in use. Does anyone know how to handle/catch this error?

Both view and modifier versions of the FamilyActivityPicker crash randomly when selecting some items (usually the other option) throwing these in the console: [com.apple.FamilyControls.ActivityPickerExtension(1150.1)] Connection to plugin invalidated while in use AX Lookup problem - errorCode:1100 error:Permission denied portName:'com.apple.iphone.axserver' PID:22091 ( 0 AXRuntime 0x00000001c603b0fc _AXGetPortFromCache + 800 1 AXRuntime 0x00000001c603cce0 AXUIElementPerformFencedActionWithValue + 700 2 UIKit 0x0000000230de3ec8 DDE6E0C5-2AC3-3C73-8CFE-BC88DE35BB5F + 1453768 3 libdispatch.dylib 0x0000000103ef0b98 _dispatch_call_block_and_release + 32 4 libdispatch.dylib 0x0000000103ef27bc _dispatch_client_callout + 20 5 libdispatch.dylib 0x0000000103efa66c _dispatch_lane_serial_drain + 832 6 libdispatch.dylib 0x0000000103efb408 _dispatch_lane_invoke + 408 7 libdispatch.dylib 0x0000000103f08404 _dispatch_root_queue_drain_deferred_wlh + 328 8 libdispatch.dylib 0x0000000103f07a38 _dispatch_workloop_worker_thread + 444 9 libsystem_pthread.dylib 0x00000001f0824f20 _pthread_wqthread + 288 10 libsystem_pthread.dylib 0x00000001f0824fc0 start_wqthread + 8 ) This also happens in production apps like the Opal.

I really appreciate any help you can provide.

What are guidelines for apps being released in the US App Store in order to comply with The Texas App Store Accountability Act? I mean there's no way to differentiate an app downloaded in Texas from the other states and it would be ridiculous to add location awareness to an app to comply with this, so effectively it means any developer of any app for release in the US must comply with this in case it might be being used in Texas? This new Apple API has zero background, zero context, zero example of usage, zero guidelines about how to use it in practice: https://developer.apple.com/documentation/declaredagerange/

Hello, I have an AppClip technical issue I'd like to ask about: Our Xiaohongshu App (Version 9.14 & Build 9140845 & appid 741292507) was submitted to the App Store for review on December 18th and approved on December 19th, starting a phased rollout. This version was the first to support AppClip functionality, and as of today the app has been fully rolled out, but I still cannot activate the Xiaohongshu App Clip Card using the NFC tag (built-in URL: https://xhslink.com/n/22UG9jlaOfv?sourceid=911). I checked all the configurations of our project's AppClip target (Associated Domains:appclips:xhslink.com), the default experience in the ASC backend (URL: https://appclip.apple.com/id?p=com.xingin.discover.Clip), and the advanced experience (URL: https://xhslink.com/n/Arxpo4IVY9X), and all showed no abnormalities. Furthermore, the default experience URL, after being written with an NFC tag, can be successfully launched by tapping the NFC tag to open the Xiaohongshu App Clip Card, and the Card can also be opened normally in Safari on the phone. However, our advanced experience URL, after being written with an NFC tag, cannot be launched by tapping the Card. Therefore, my question is: Who please can help me check why the Xiaohongshu App Clip Card cannot be launched normally using the advanced experience URL? Thank you very much! My Expectations: My advanced experience URL configured on the ASC platform, such as https://xhslink.com/n/Arxpo4IVY9X, should be recognized and validated by the iOS system when the phone is near the NFC tag and reads https://xhslink.com/n/22UG9jlaOfv?sourceid=911, ultimately triggering the App Clip Card configured in Xiaohongshu's advanced experience settings. Additionally: We have already deployed a large number of NFC tags and other materials in many online stores, and the URL (https://xhslink.com/n/Arxpo4IVY9X) is built-in, and our 9.14 version is fully implemented. However, the newly developed App Clip feature is not working, which is very urgent and I hope Apple can help me find the cause of the problem and how to improve it as soon as possible. Thank you very much!
