AVAudioSession API for setting stereo orientation on supported devices (iPhone XS and above) is completely broken on iOS 15 betas. Even the 'Stereo Audio Capture' sample code does not work anymore on iOS 15. Even AVCaptureAudioDataOutput fails when setting stereo orientation on AVAudioSession. I am wondering if Apple Engineers are aware of this issue and whether this would be fixed in upcoming betas and most importantly, iOS 15 mainline.

I opened Editor -> Add Capability but there is no option to add User Assigned Device Name in the list! User Assigned Device Name
