I am using AVAudioEngine, I have a stereo wav file that I want to use with an AVAudioEnvironmentNode but it requires the input source is mono otherwise it will not spatialize the sounds. Is there some way I can convert the stereo input to mono dynamically, maybe using an avaudiomixernode or something else? It looks like maybe I can use AVAudioConverter to convert the original buffer, but I want to be able to just add a node in the AVAudioEngine graph that can convert it to mono if that is possible, rather than having to convert the input buffer explicitly. So something like: WAV -> AVAudioPlayerNode -> Stereo to mono node -> AVAudioEnvironmentNode

The docs for this property say: "Apps that play long-form audio, such as music or audio books, can use this policy to play to the same output as the built-in Music and Podcast apps. Long-form audio apps should also use the Media Player framework to add support for remote control events and to provide Now Playing information." That doesn't really say what the benefit is for adding this option or what are the drawbacks? Does somebody have some more information on when you should use this policy and potential issues it might cause? We are working on a music app that will play music in the background so it sounds like we should add this policy, but I can't find any information about why you should. Thanks

Is there any information on what the AudioPlaybackIntent does? The documentation doesn't give any information on it: https://developer.apple.com/documentation/appintents/audioplaybackintent I have an audio app and I want to add a play/pause button to our widget for iOS17, I'm assuming I need to use an AudioPlaybackIntent but there is no documentation on what it does. Thanks.

I see this warning a lot in console.log when my widgets update, is it just noise or is there something I could be doing wrong in my widgets. I don't do anything explicitly with the runloop in my code, it's just regular SwiftUI to render a widget.

I'm using the LockedCameraCaptureExtension to launch my Camera app from the camera button. Some of our users report our app crashing a few seconds after being launch from the camera button. The call stack is something inside BoardServices [BSServicesConfiguration activateXPCService] I'm not sure how to investigate or fix this, anyone else having the same issue? Basically in my LockedCameraCaptureExtension when it loads I just call openApplication on the LockedCameraCaptureSession to launch into my app. @main struct captureExtension: LockedCameraCaptureExtension { var body: some LockedCameraCaptureExtensionScene { LockedCameraCaptureUIScene { session in Button(action: { Task { await openCamera(session: session) } }, label: { Text("Open Camera") }) .buttonStyle(PlainButtonStyle()) .task { await openCamera(session: session) } } } private func openCamera(session: LockedCameraCaptureSession) async { try? await session.openApplication(for: NSUserActivity(activityType: "com.mycompany.camera")) } }

In SwiftUI I am using the manageSubscriptionsSheet modifier to open the iOS subscription screen. When this is presented it immediately flashes a white view and then animated the subscription screen up from the bottom, it looks pretty bad. The view I am calling manageSubscriptionsSheet on is presented in a sheet, so maybe trying to present the subscriptions view as well is causing the visual glitch. Any way to not have this white flashing view when opening the subscription screen?
