I am having an issue with the code that I posted below. I capture voice in my CarPlay app, then allow the user to have it read back to them using AVSpeechUtterance. This works fine on some cars, but many of my beta testers report no audio being played. I have also experienced this in a rental car where the audio was either too quiet or the audio didn't play. Does anyone see any issue with the code that I posted? This is for CarPlay specifically. class CarPlayTextToSpeechService: NSObject, ObservableObject, AVSpeechSynthesizerDelegate { private var speechSynthesizer = AVSpeechSynthesizer() static let shared = CarPlayTextToSpeechService() /// Completion callback private var completionCallback: (() -> Void)? override init() { super.init() speechSynthesizer.delegate = self } func configureAudioSession() { do { try AVAudioSession.sharedInstance().setCategory(.playback, mode: .voicePrompt, options: [.duckOthers, .interruptSpokenAudioAndMixWithOthers, .allowBluetoothHFP]) } catch { prin

We are also facing similar issue the follow-up frames I send are not receiving any response. . Did you get any response from apple or breakthrough for this? As per my understanding, once initiate bootstrapping follow up frame and apple device respond with follow up frame. it may be pop up pin which need to use for PASN exchange later.

UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom]; backBtn.frame = CGRectMake(0, 0, 44, 44); [backBtn setImage:[UIImage imageNamed:@back] forState:UIControlStateNormal]; [backBtn addTarget:self action:@selector(gotoBack) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *backItem = [[UIBarButtonItem alloc] initWithCustomView:backBtn]; // backItem.hidesSharedBackground = YES; // backItem.tintColor = [UIColor redColor]; self.navigationItem.leftBarButtonItem = backItem; I am using Xcode 26, which is compatible with iOS 26. After I set up the back button of the navigation bar, why are the background colors of the back buttons on some pages gray? When I pushed the new page, after popping back to the current page, the buttons with the gray background turned back to the white background. This issue will also affect the rightBarButtonItem.

Hey everyone. Ever since installed OS26 (and 26.1 now) - whenever I fast play any video on 1.25x, 1.5x, 2x on the AppleTV - the audio gets massively distorted on HomePods. Be it on YouTube, Difuse, or any supporting app. I even tried mirroring from iPhone -same issue. Anyone else experiencing the same? I noticed no posts about troubleshooting.

I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor
And when PTT notification arrives, saving the URL to the audio file in incomingPushResult, then downloading and playing that sound using AVAudioPlayer when didActivate is executed. It's working fine on the foreground, but when the app goes to the background, incomingPushResult is called as expected, but didActivate is not for some reason. Am I missing anything in my setup? Yes. The issue here is that you can't use AVAudioPlayer, as it does its own AudioSession activation. More specifically: It's working fine on the foreground. It works in the foreground app because the foreground app has inherent access to the audio system and can do whatever it wants. However: when the app goes to the background, incomingPushResult is called as expected, but didActivate is not for some reason. ...what happens in the background is that the same activation attempt then occurs and either fails entirely or succeeds (partially) but is then disrupted by callservicesd's own activation. Unfortunately, you'

Error: RoomCaptureSession.CaptureError.exceedSceneSizeLimit Apple Documentation Explanation: An error that indicates when the scene size grows past the framework’s limitations. Issue: This error is popping up in my iPhone 14 Pro (128 GB) after a few roomplan scans are done. This error shows up even if the room size is small. It occurs immediately after I start the RoomCaptureSession after the relocalisation of previous AR session (in world tracking configuration). I am having trouble understanding exactly why this error shows and how to debug/solve it. Does anyone have any idea on how to approach to this issue?
Hi everyone, I'm running into an issue with AVAudioRecorder when handling interruptions such as phone calls or alarms. Problem: When the app is recording audio and an interruption occurs: I handle the interruption with audioRecorder?.pause() inside AVAudioSession.interruptionNotification (on .began). On .ended, I check for .shouldResume and call audioRecorder?.record() again. The recorder resumes successfully, but only the audio recorded after the interruption is saved. The audio recorded before the interruption is lost, even though I'm using the same file URL and not recreating the recorder. Repro: Start a recording with AVAudioRecorder Simulate a system interruption (e.g., incoming call) Resume recording after the interruption Stop and inspect the output audio file Expected: Full audio (before and after interruption) should be saved. Actual: Only the audio after interruption is saved; the earlier part is missing Notes: According to the documentation, cal
I'm developing for compliance with Texas law in the United States. Currently, I'm encountering an issue where I want to test the feature point when the app undergoes significant changes, a supervised user initiates a request. However, during actual testing, the app pops up an error message: Can't Ask, An Unknown error occurred. Additionally, I see the following error message in the Xcode Console: Error Domain=AskToCore.ATMessageComposeValidationError Code=4 'The user is in a region that does not support this type of ask.' UserInfo={NSLocalizedFailureReason=The user must be in a supported region to use this feature., NSLocalizedRecoverySuggestion=Please ensure the user is in an eligible region., NSLocalizedDescription=The user is in a region that does not support this type of ask.} I am indeed not in the Texas region. I want to conduct full-process testing before the feature is released to the App Store. What should I do? Apart from Sandbox testing (which, in fact, doesn't show any pop-ups either), ho
Hello @DTS Engineer ! I would like to add that there is another, maybe related, issue. When a user uses AirPlay to stream a video from another app and opens video in my app, which is intended to play only on device - everything works as expected. But when a user opens a video in my app, which is allowed to be played through AirPlay, plays it on external screen, than closes a video, but does not disconnect AirPlay, and opens another screen where plays a video, that should stay on device, audio of that video starts to play through AirPlay. The same situation when there are 2 players on the second screen, where one plays video without audio and the other plays only audio. Player with only audio starts playback on external screen. I wonder if there is a way to signal to AVPlayer to stop trying to use AirPlay for other players, because ‘allowsExternalPlayback = false’ does not work and audio still tries to play through AirPlay. Thank you!

Hello @erawq, There is no reliable way to disconnect your app's audio playback from an AirPlay route (aside from the user taking action to change the route in Control Center for example). From AVAudioSessionTypes.h: - AVAudioSessionCategoryPlayAndRecord: /// DefaultToSpeaker will default to false, but >can be set to true, routing to Speaker /// (instead of Receiver) when no other audio route is connected. The key phrasing here is (instead of Receiver) when no other audio route is connected. In other words: try audioSession.setCategory(.playAndRecord, options: .defaultToSpeaker) This call is only expected to have an effect when audio is currently being routed to the device's receiver (the speaker which on most devices is at the top near the front-facing camera). In your case, audio is being routed to an AirPlay route, so it is expected that this call should not have an effect. If you would like the capability of programmatically disconnecting from an AirPlay rout

Thanks, i figure the issue is on the flutter side but just wanted to check here if there is any way its possible for the audio to stop working only when downloading through test flight / app store And yes that is correct to your first statement

I have a flutter iOS app that has some simple sound FX for button clicks, swipes, etc. In simulator and on real device the sound works fine, but when i upload the app to testflight (and App store) the sound FX don't play. When I upload the app to my phone via xcode I am using the release profile so I don't see what the difference could be. I have also gone through the archive that i uploaded and verified that the sound files are indeed there. I have other flutter apps that use sound but non since the iOS 26 update. I've tried 3 different flutter sound libraries and all face the same issue. Wondering if anyone else is seeing this issue or if I'm missing a simple permission or something that has changed recently? Thanks in advanced

My implementation was not including the show password button in the UI when VoiceOver was enabled. @kthchew that's a good point about letting the user manage their risk. Especially if they're wearing headphones. Should I were to include it again, and give the option to the user to speak the password; I probably wouldn't want the accessibility label to be Show Password Perhaps something such as Speak Password? Where the accessibility hint would then indicate that by double tapping the system will speak their password out. Does that sound reasonable or would something else be better for the accessibility label? What about password requirements? My thoughts are if you have a list of password requirements, that UI containing the accessible list of Password requirements should come before the actual password field when VoiceOver is enabled. This way the user knows what the requirements are before they start entering a password.
