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.

Hi All, I am facing one problem in my app. That is open battery settings from my app. It is working fine in iOS 16.0.0 and it's not working in iOS 18.6.1 is it possible to make it workable in iOS 18.6.1? If so How to do that? Please help me over this to resolve the problem. Thanks, Nguyen Quang Minh

We have found a large number of memory-related crashes in iOS18, and multiple issues have finally pointed to this crash line xzm_xzone_malloc_tiny_outlined. Do not know how to solve it now

In my application, I use CallKit and have supportsHolding = true set. During my phone call, another call comes in (e.g., GSM). I accept the incoming call and put the current call on hold. If I end the active call myself, everything is fine, and CallKit calls the method provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession). However, if the other party ends the call, the second call remains on hold. In the application, the user clicks on unhold, and I notify CallKit that the hold has ended. But in this case, the didActivate method is not called at all. If I try to activate the audio myself after unhold, I receive the error: Domain=NSOSStatusErrorDomain Code=561017449 "Session activation failed" UserInfo={NSLocalizedDescription=Session activation failed} AVAudioSessionErrorInsufficientPriority == NSOSStatusErrorDomain Code: 561017449 What needs to be done for CallKit to activate my audio?

We are integrating Apple’s DeclaredAgeRange SDK. To comply with relevant regulatory requirements, our understanding is as follows: The app is only required to obtain the declared age range for users located in Texas. For users outside of Texas, we should not proactively request age range information. Accordingly, we would like to confirm the following: Are we required to present the age range request prompt to all users in the United States? If yes, we are concerned that this may significantly impact the overall user experience. If it is permissible to request age range only for Texas users, how can we reliably determine whether a user is located in Texas on the client side? For example, does Apple provide an API or recommended method for accurately identifying a user’s region (specifically Texas)?

I have also tested this on iOS 26 (Beta 9 and above), and the CallKit call blocking functionality is not working. Numbers that should be blocked still ring through. Caller Identification continues to function as expected, but blocking entries (addBlockingEntry) are ignored.

In a project having both an app and a website, the following two website urls are to be handed over to the corresponding app: https://www.example.com/search?plus https://www.example.com/search?query=something In AASA file, this becomes: "components": [ { "/": "/search", "?": { "plus": "", "query": "?*" } } However, finally it does not work for both urls. Only the one with "query" works by hand over to app. For investigation, I have tried this for the problematic link: "components": [ { "/": "/search", "?": "plus" } and this works. How can I get both to work? (note that for the sake of brevity, only a portion of the AASA files are shown)

Using Apple SwiftUI Translate library: when calling: try await session.prepareTranslation() the first time, the API's Language Download sheet does not show (or shows briefly and dismisses immediately) Even when the sheet doesn't show, the keyboard is lowered, as though the sheet would be appearing, but then the keyboard raises as though the sheet was dismissed. The following Errors are printed in the console dozens of times; but on all subsequent executions, the API Language Download sheet shows as expected. The trigger code is in a function which is executed when a Translate button is tapped. Any ideas would be welcome!

Hello everyone, I’m currently receiving feedback from clients in a production environment who are encountering a BadDeviceToken error with Live Activities, which is preventing their states from updating. However, for other clients, the token is working fine and everything functions as expected. I’m collaborating with the back-end developers to gather more information about this issue, but the only log message we’re seeing is: Failed to send a push, APNS reported an error: BadDeviceToken I would greatly appreciate it if anyone could provide some insight or information on how to resolve this issue.

Hello, I want to echo the DeviceActivityReport "concurrency" problems flagged in https://developer.apple.com/forums/thread/720549, and ask a related question. (Thanks to Kmart and other Apple dev support folks who have been monitoring these forums and responding diligently.) I would like to display daily and weekly stats in the same view, broken down by specific apps (as in the native Screen Time). However, instantiating multiple DeviceActivityReport objects with different filters and/or different contexts leads to confusion, where the two views will incorrectly and intermittently swap data or duplicate data where it shouldn't (seemingly upon some interval when the extension provides fresh data). There isn't documentation on how to display multiple reports at once. Is the idea that logic for multiple reports should be embedded within the extension itself in the makeConfiguration() function and there should only be a single DeviceActivityReport in the main App, or is this a bug? Even with a single DeviceActivityReport, I run into inconsistencies where the View provided by the extension takes multiple seconds to load or fails to load altogether. The behavior seems random...I will build the application with the same code multiple times and see different behavior each time. Finally, a plug for better support in the Simulator for the entire set of Screen Time APIs. Thanks!

Hey! I'm trying to create an XPC messaging feature between my daemon and main application. I'm trying to use the new Swift low-level API available from macOS 14.0. The documentation is extremely confusing when looking at it from Swift: The xpc_listener_t type Seems to be something I shouldn't use in the Swift API, and would rather have to use XPCListener. Also, it appears to have no public API other than the xpc_listener_set_peer_code_signing_requirement function. Which would make it impossible to create this type. However, when going into xpc.h, one can see that there is an API in fact: API_AVAILABLE(macos(14.0), macCatalyst(17.0)) API_UNAVAILABLE(ios, tvos, watchos) XPC_EXPORT XPC_SWIFT_NOEXPORT XPC_RETURNS_RETAINED XPC_WARN_RESULT xpc_listener_t _Nullable xpc_listener_create(const char * service, dispatch_queue_t _Nullable target_queue, xpc_listener_create_flags_t flags, xpc_listener_incoming_session_handler_t incoming_session_handler, xpc_rich_error_t _Nullable * _Nullable error_out); which is a very unusual declaration - the first parameter for example shows up as Int8 type in Swift. Not to mention I haven't been able to create the next parameter, xpc_listener_create_flags_t at all, even though it seems to be a UInt64-based flag based on the C declaration, but passing UInt64(0) throws a compiler error. It really seems like something I shouldn't use from Swift. But then again, the extremely important security-related API mentioned above, xpc_listener_set_peer_code_signing_requirement can only take an xpc_listener_t object as a parameter, not an XPCListener type. There seems to be no conversion available between the two. However the documentation in the XPC framework seems to be telling the story of these two types being very equal, because of the following: The xpc_session_t type seemingly again has only deprecated methods mostly, the important one staying behind is xpc_session_set_peer_code_signing_requirement. However, this would again require the creation of an xpc_session_t object, for which in the XPC framework one will find declarations like: @available(macOS, introduced: 13.0, deprecated: 14.0, renamed: "XPCSession") @available(macCatalyst, introduced: 16.0, deprecated: 17.0, renamed: "XPCSession") @available(iOS, unavailable) @available(tvOS, unavailable) @available(watchOS, unavailable) public typealias xpc_session_t = OS_xpc_object plus basically all API of XPCSession being originally declared as xpc_session_* APIs and all of them having deprecated: 14.0, renamed: * marks. This is telling me xpc_session_t and XPCSession are in fact the same/same-ish. But again, there is seemingly no conversion between these two types. Which brings me to again being unable to create a code signing requirement for the XPCSession object. I've read some older forum posts, and I saw Apple Engineers admitting the code signing requirement APIs are missing from the new Swift APIs, however they seem to have been added in macOS 14.4 - although it appears to have been mistakenly added to the C-family functions, which have not been exposed to Swift correctly, because they still use the deprecated xpc_listener_t and xpc_session_t types. So my question is: what is going on here? :) Making XPC connections without a code signing requirement in 2025 seems like a no-go, so do I have to still stick with C - even though this new API seems to be focused on Swift?

Is this intended behavior? I want my app to act like the regular Clock app and snooze alarms when user taps volume down button but apparently volume down button stops the alarm. Is this normal or am I missing something?

Hi Apple Developers, I am currently working on a message filtering application and facing issues specifically with filtering RCS (Rich Communication Services) messages. To debug this, I created a sample app that consistently categorizes all incoming messages as "junk." However, the filtering behaviour is inconsistent and not functioning as expected. Here are the key issues observed during testing on iOS versions 18.2.1 and 18.3: Inconsistent Filtering Behavior: When a message is received from an unknown number, it sometimes gets moved to the Junk folder momentarily but is then immediately moved back to the main Messages inbox. In some cases, the message does not get moved to the Junk folder at all, despite the app returning the verdict as "junk." Duplicate Contact Tiles: The Messages app displays two separate conversation tiles for the same mobile number, which is unexpected behavior. I have attached both a sample app and a screen recording that clearly demonstrates the issue. The recording shows that the app categorizes messages as junk, yet they still end up in the main Messages inbox. For reference, my carrier partner is T-Mobile. Please let me know if you need any additional information to investigate this issue further. Looking forward to your insights and guidance. Best regards, Rijul Singhal

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.

We are a research team conducting a study collecting subject's SensorKit speech data, and we've encountered some questions we couldn't resolve ourselves or by looking up the online SensorKit documentation: Microphone Activation: In general, how is the microphone being turned on to capture a speech session? And how was each session determined to be an independent session? Negative Values: In the speech classification data, there are entries where some of the start and end values are negative (see screenshot below). How should we interpret and handle these values? Is it safe to filter them out? Duplicated sessions: From the same screenshot you can see there are multiple session identifiers linked to the same subject with the same timestamp - what does this represent? Another Negative Values: The same question for speech recognition data's average pause duration, what does the -1 mean and should we remove them as well? (Note that these screenshot got rid of subject IDs for privacy purposes but each screenshot was from one subject.) We greatly appreciate your time and help.

Hello, I’m presenting the familyActivityPicker from a presented sheet in my application. When I select some apps, categories or websites and tap “Done”, the familyActivityPicker is dismissed but the presenting sheet is also dismissed on iOS 18.4, iOS 18.5, iOS 26 beta 1 and 2. If I tap on “Cancel” from the familyActivityPicker, the sheet is also dismissed on iOS 18.4, iOS 18.5, iOS 26 beta 1 and 2. The same code works perfectly fine on iOS 18.0, iOS 18.1, iOS 18.2 and iOS 18.3. Is this a known-issue? If opened the feedback FB18369821 for this. Regards, Axel

We have a Share Extension that fails in Photos on macOS when trying to share a JPEG image for the following reason: From the NSItemProvider we get from the NSExtensionItem.attachments, we try to load the image using loadFileRepresentation(forTypeIdentifier: “public.image”, completionHandler: …). This fails for .jpeg images in the library. There seems to be a mismatch in expected and actual file extension internally. Here is the log: Error copying file type public.image. Error: Error Domain=NSItemProviderErrorDomain Code=-1000 "Cannot load representation of type public.jpeg" UserInfo={NSLocalizedDescription=Cannot load representation of type public.jpeg, NSUnderlyingError=0x1527c1a80 {Error Domain=NSItemProviderErrorDomain Code=-1 "Cannot copy file at URL file:///Users/frank/Library/Containers/com.apple.Photos/Data/tmp/TemporaryItems/ShareKit-Exports/7CCFA760-AAC9-42B0-812D-68F051ED1543/F912E593-2BE5-4E70-86AB-7657A40657E5/IMG_3517.jpg."

Certainly! Here's a concise version of your forum post: Title: Issues Handling Multiple Incoming Calls in CallKit Body: Hello, I'm using CallKit and I am encountering challenges with handling multiple incoming calls. Current Configuration: configuration.maximumCallsPerCallGroup = 5 configuration.maximumCallGroups = 3 This setup aims to allow up to 5 calls per group. Observed Behavior: Despite the configuration, the system UI seems to limit the number of calls per group, often defaulting to "End & Accept" instead of "Hold & Accept" when a third call comes in. Questions: Is there a documented system-imposed limit on the number of calls per group or total calls, even if maximumCallGroups and maximumCallsPerCallGroup are set higher? How does the system UI behave when these limits are exceeded? Are there known UI constraints or fallback behaviors? Are there best practices for handling scenarios where the system UI cannot display all calls, such as gracefully managing incoming calls or providing alternative UI solutions? Any insights or experiences with similar configurations would be greatly appreciated. Thank you. Feel free to copy and paste this directly into the Apple Developer Forums. If you need further assistance or adjustments, let me know!
