Satellite Communication framework, experiences a failure in receiving network path updates when a device transitions from Satellite to a fringe LTE area. The iOS Status Bar correctly updates to show "LTE," but our application does not receive the corresponding network path update (e.g., via NWPathMonitor). This leaves our app UI locked in "Satellite Mode," while the user sees "LTE" in the status bar, causing critical user confusion. Feedback: FB20976940

Rejecting a Cellular Call Also Rejects Application Video Call Steps: 1.When a user receives a cellular call and it is in the "ringing" state and application receives a video call which is reported to CallKit 2.User rejects the Cellular call from Callkit UI, Video call is also getting rejected. 3.Application is receiving performEndCallAction when user is rejecting the Cellular call As a part of CXcallobserver Application is receiving call connected then disconnected for the cellular call Irrespective of OS, the issue only reproduces on cellular calls if Live Voicemail is enabled. Issue is not reproduced when Live Voicemail is disabled for cellular calls, and it is not reproducing on FaceTime calls, regardless of the Live Voicemail setting. This results in a poor user experience because: The recipient unintentionally misses the CallKit-reported call. The initiator receives confusing and inaccurate status information, believing the recipient is busy rather than having chosen to decline the pending video call.

"We are developing an application use case that requires us to prompt the user to restart their device. We plan to use the system uptime value provided by [NSProcessInfo processInfo].systemUptime to determine if a restart has occurred. Apple's documentation defines this API as 'The amount of time the system has been awake since the last time it was restarted.' Our questions are: Can we reliably use this API, in conjunction with persistent storage, to detect a device restart? Are there any known limitations or considerations when accessing or relying on this API while the application is running in the background?"

We have utilised the KeyChain Framework for Adding items into KeyChain. We have Generated KeyPair using 'SecKeyGeneratePair' API as below (OSStatus)generateAssymetricKeyPair:(NSUInteger)bitSize{ OSStatus sanityCheck = noErr; SecKeyRef publicKeyRef = NULL; SecKeyRef privateKeyRef = NULL; NSString *appGrpIdentifier = @"group.com.sample.xyz" // Set the private key attributes.

Could you please explain in detail on this. https://developer.apple.com/help/app-store-connect/transfer-an-app/overview-of-app-transfer Keychain sharing continues to work only until the app is updated. Therefore, you must rebuild the keychain when submitting updates. If your keychain group is defined in the Xcode project, replace it with a group created by the recipient, incorporating their Team ID for continued keychain sharing. After the update, users must re-login once as the app cannot retrieve the authentication token from the keychain.

Let the device is in locked screen Get incoming APNS video request to start video recording we are reporting this APNS to Callkit Accept incoming APNS request We are trying to initialise audio unit. Initialisation is success but starting is failing. Note - This issue is reproduced only if we receive video pull request in locked screen, after accepting callkit call we should not unlock the phone. If we unlock phone everything works as expected.

We have a push-to-talk client, Part of Push APNS, app never received the BG task expiry. The app is suspended. Received Push-To-Talk APNS Here requested a BGTask and it got successfully registered Since it is a PTT call path, it ended immediately(via code) due to internal restrictions Ex: DND mode for client specific. The client allowed BG time more than 30 seconds and looks client has been suspended but Never received a BG task expiration handler from OS In sys diagnose logs confirmed, BGTask registered successfully 2024-09-03 16:18:47.331890 +0530 default AT&T EPTT : Created background task .

We have a Push-To-Talk application, which also allow user's to share the PDF file documents. On receiving a PDF file document, which has a space in its file name. On saving the document in the DB with space. When user is trying to access the PDF file, in order to rule out issues where there can be special character's in its file name, we are encoding the file name using stringByAddingPercentEncodingWithAllowedCharacters, and URLPathAllowedCharacterSet is the character set used which converts space character (" ") to %20. Later, path of the same encoded file name is sent to fileURLWithPath:. When the encoded URL is passed to [NSFileManager fileExistsAtPath:] the file is not found in the since in DB, file is saved with a space, but in the URL %20 is been swapped in-place of space character. Issue case: Here, on passing the same encoded URL path of the PDF file to [NSFileManager fileExistsAtPath:] is returning false; Query: On passing the filename with spaces encoded with stringByAddingPercentEncodingWithAllowedCharacters to [NSFileManager fileExistsAtPath:], the path is not converted back to the decoded file name and returning false We have used a work around on this case, by forming the URL of the PDF file without encoding and passing it to fileURLWithPath, issue is not seen here. We have a query here, i.e. will fileURLWithPath will be able to handle different special characters without encoding. We have also raised a Feedback Ticket on same: https://feedbackassistant.apple.com/feedback/16049504

We have a Push To Talk application which allow user to record video and audio. When user is recording a video using AVCaptureSession and receive's an Push To Talk call, from moment the Push To Talk call is received the audio in the video which is being captured is stopped while the video capture is still in progress. Here after the PTT call is completed, we have tried restarting the audio session, there are no errors that are getting printed but we still don't see the audio getting restarted in video capture. We have also tried to add a new input for AVCaptureSession we are receiving error that is resulting in video capture stopping, error mentioned below: [OS-PLT] [CameraManager] Movie file finished with error: Error Domain=AVFoundationErrorDomain Code=-11818 "Recording Stopped" UserInfo={AVErrorRecordingSuccessfullyFinishedKey=true, NSLocalizedDescription=Recording Stopped, NSLocalizedRecoverySuggestion=Stop any other actions using the recording device and try again., AVErrorRecordingFailureDomainKey=1, NSUnderlyingError=0x3026bff60 {Error Domain=NSOSStatusErrorDomain Code=-16414 "(null)"}}, success We have also raised a Feedback Ticket on same: https://feedbackassistant.apple.com/feedback/16050598

An issue with the CallKit UI, specifically regarding the functionality of the speaker button. When a user initiates a video call with CallKit and then, using the existing CallKit session, initiates an audio call, there are no issues with CallKit or the audio. However, if the user terminates the video call from the CallKit UI, the active CallKit session ends. To resume the ongoing audio call, we report a new CallKit call upon the end call trigger. While there are no issues with this reporting, the CallKit UI does not provide an audio route for the built-in receiver, and the speaker button remains unresponsive. IPA was build on SDK 18 and running on iOS beta 26. Issue is NOT seen with SDK18 and running iOS 18.x or lower devices. Feedback - FB18855566

We're currently migrating from AppDelegate to UISceneDelegate due to console warnings . Our application's UI, which is built on a single webpage, functions correctly when launched in the foreground after this migration. However, we've encountered an issue with partial rendered UI components when launching the application from the background, such as upon receiving a VoIP call. During a background launch, the following delegate calls occur before the client attempts to load a local webpage: [08/07 16:25:49:037][ 0x101ea3910]<ALA_SIGNAL>: [OS-PLT] Exit -[AppDelegate application:didFinishLaunchingWithOptions:] [08/07 16:25:49:084][ 0x10c0c4140]<PushToTalk> [Pushnotif] [] <ALA_SIGNAL>: [OS-CCF] Enter -[PushNotificationManager pushRegistry:didReceiveIncomingPushWithPayload:forType:withCompletionHandler:] [08/07 16:25:49:098][ 0x101ea3910]Begin -[SceneDelegate scene:willConnectToSession:options:] [08/07 16:25:49:098][ 0x101ea3910]Exit -[SceneDelegate scene:willConnectToSession:options:] As part of client login process we load the index page in WebKit here: [08/07 16:25:50:977][ 0x101ea3910]<ALA_SIGNAL>: [PLT-OS] Enter -[SceneDelegate loadUI:] [UI Launch Reason = 1] Code: NSString *path = [[NSBundle mainBundle]pathForResource:@"index" ofType:@"html" inDirectory:@"www"]; NSURL *urlReq = [NSURL fileURLWithPath:path]; [webView loadFileURL:urlReq allowingReadAccessToURL:urlReq]; The problem we're observing is that the webpage is only partially rendering in this background launch scenario (Seen after brought to FG). Any insights or assistance you can provide would be greatly appreciated.

Applicaiton is built with WebKit and native camera view controller . Issue is seen always when presenting a UIVideoEditorController class on top of MainVC(webKit).

Observed few times that providerDidBegin(_:) delegate never called for the complete app session after app init(as part of this CXProvider registered) which was built with SDK 26 and running on iOS 26. This issue observed multiple times with our testing. Since there is no providerDidBegin:, client is marking CallKit as not ready and never report any calls for VoIP APNS and ended up in app crash due to "[PKPushRegistry _terminateAppIfThereAreUnhandledVoIPPushes]" Please refer for sysdiagnose logs : FB19778306

We've observed an issue where the video button on the CallKit UI is disabled during Video VoIP calls. This issue appears to be specific to notch devices running SDK 26 and iOS 26 beta 7, specifically on iPhone 11. We have not seen this behavior on devices with Dynamic Island or on older iOS versions. For further details, please refer to the attached video and sysdiagnose file. : FB19827793 Our experimentation suggests this issue is exclusively present on non-Dynamic Island devices with iOS 26 beta.
