Reply to App Crashes. I have many view controllers
It sounds like you are pushing more and more view controllers onto the navigation controller's stack, or you have a whole series of view controllers that are presenting another view controller. I think you need to pop the previous view controller off the navigation controller's stack before presenting the next one, or dismiss the previous view controller before presenting the next one.

Does not play different sound when different sound is selected
When a different sound is selected in a TableView, the name of the sound is added to a variable. In a different view controller, it is supposed to access the variable and play the sound when a button is pressed, though it instead just plays the same sound. Here is the code:FirstSoundController (Plays Sound):class FirstViewController: UIViewController { var someVariable = SecondViewController() @IBAction func activation(sender: UIButton) { if sender.titleLabel!.text == ACTIVATE { sender.setTitle(DEACTIVATE, forState: UIControlState.Normal) var someSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(someVariable.soundSelected, ofType: mp3)!) audioPlayer = AVAudioPlayer(contentsOfURL: someSound, error: nil) audioPlayer.prepareToPlay() audioPlayer.play() } else { sender.setTitle(ACTIVATE, forState: UIControlState.Normal) audioPlayer.stop() }}SecondViewController (Shows table of Sounds):class SecondViewController: UIViewController, UITableViewD

Missing Destination when "pop to" root View
I have referred to this Stack Overflow thread SwiftUI How to Pop to root view - https://stackoverflow.com/questions/57334455/swiftui-how-to-pop-to-root-view However it doesn't work for my case, of course no answer fits each persons use case perfectly so one always has to modify the answer slightly but of course keeping to the overall outline of the solution. The solution I went with is use an ObservableObject and set it as an EnvironmentObject of the root view. The navigation stack grows by 4 views: RootView().environmentObject(AppSettings.shared) FirstView() SecondView() ThirdView() FourthView() The NavigationLink isActive state for the FirstView is defined in AppSettings.shared, all the other states are found in the subsequent view and not in AppSettings. For example: FirstView -> SecondView the SecondView isActive state is defined in the ViewModel of the FirstView, and so on and so forth. What I am trying to achieve is to pop to RootView from the FourthView. So on the FourthVi

Reply to AVAudioEngine how to start engine without NSAssert
Hi Steve,We're actually in the process of updating the AVAE samples adding new functionality, fixing bugs etc. so it's a good time catching this now so we can update everything at once as the NSAssert's are removing critical lines of code from being compiled in with the release build which is of course bad.As for the popping...engineering informed me that this is a known issue where fades are not applied between buffers that get interrupted or stopped resulting in the popping very apparent with low frequency audio. Your work around is fine but annoying to have to deal with - we're hoping to address the issue in a future release (but as you know it's impossible for us to be more specific regarding when a fix will be available).

No sound when playing audio over car system with Bluetooth
Hi I am developing an app which plays spoken audio. I experience problems when I want to play audio over the car system with Bluetooth. The Bluetooth connection is fine and other audio apps (e.g. Spotify) just work fine. When I want to play audio with my app, I can start audio playback successfully but I hear no sound. It works with the device speakers and interestingly even with another mobile Bluetooth sound box. Both the car system and the mobile soundbox use A2DP. Below you can find the relevant method that starts the audio playback. The full app can be found at https://gitlab.com/spiri-voyage/spiri-test. func play() { if playbackState == .Stopped { let url = Bundle.main.path(forResource: Kolinbrunnen, ofType: mp3) let item = AVPlayerItem(url: URL(fileURLWithPath: url!)) player.replaceCurrentItem(with: item) let audioSession = AVAudioSession.sharedInstance() do { try audioSession.setCategory(.playback, mode: .spokenAudio) addInfo(Audio

Spatial Audio on Mac - When and how to render using Audio Units?
I'm working on adding Spatial Audio support to a game on the Mac. I'm looking at the SpatialAudioRenderer sample but having some issues. It's unclear to me when a device is compatible with Spatial Audio and when I should attempt to render Spatial Audio. There is no property that I can find on the Mac that advertises Spatial Audio compatibility on a device. The sample crashes when the output device is a USB device. This includes the Apple Studio Display. The Apple Studio Display is supposed to be capable of rendering Spatial Audio. The device doesn't work with the sample - do I still need to render down the 7.1.4 source on this device? The sample always renders down to Stereo, but the Apple Studio Display is not a Stereo device. I'm a bit confused by the sample and when/how I should configure the mixing unit.

Audio quality
Since updating to iOS 26, audio recordings made through apps like Snapchat and Instagram sound broken, saccaded and choppy. The issue happens with or without headphones. It feels like the microphone is either misused or filtered too aggressively by the app, leading to a stuttering or “cut-off” effect during speech. This doesn’t happen when recording audio in the Voice Memos app or the Camera app — only in social media apps.

AVPlayerViewController for Audio?
The Player object available in TVJS presents a really nice UI for audio playback, is it possible to get this viewcontroller as a native component as well?For example the video version is available through AVPlayerViewController, but I can't find the equilevent audio version.

Facetime Audio?
I have an iPhone 7 and I installed iOS 12 on it. In iOS 11, in Facetime, I could choose between FT audio or FT video. Now, I don't see that option to choose between making an audio call or video.

Rating Review pop up limit Reinstall
I know through documents on the official website that there are only three opportunities a year. If the user deletes the app and then downloads it again, will the app review induction pop-up appear again?
