User Profile

In my application, I use CallKit and have supportsHolding = true set. During my phone call, another call comes in (e.g., GSM). I accept the incoming call and put the current call on hold. If I end the active call myself, everything is fine, and CallKit calls the method provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession). However, if the other party ends the call, the second call remains on hold. In the application, the user clicks on unhold, and I notify CallKit that the hold has ended. But in this case, the didActivate method is not called at all. If I try to activate the audio myself after unhold, I receive the error: Domain=NSOSStatusErrorDomain Code=561017449 "Session activation failed" UserInfo={NSLocalizedDescription=Session activation failed} AVAudioSessionErrorInsufficientPriority == NSOSStatusErrorDomain Code: 561017449 What needs to be done for CallKit to activate my audio?

I'm using UITextView. I set its background color to .white. Initially, the UITextView appears with a white background color. However, after I click on the UITextView, a cursor appears and the background color changes to .systemBackground. I am unable to change this background color by any means.

I want to implement screen recording similar to Teams, WhatsApp... I created an Upload Broadcast Extension. If I start the extension, both audio and video will start to be recorded (without CallKit). Issue: During an ongoing call (CallKit), the extension starts, but does not start recording. Called broadcastStarted(withSetupInfo:) but not called processSampleBuffer(_:, with:). The extension stops after a short while. How do I setup ReplayKit to work together with CallKit? Is it possible that the CallKit audio setting does not allow ReplayKit recording? Is it possible to turn off audio in ReplayKit and request only video?

When i make a call within our VOIP application (ipadOS app on MacOS and M1 - MBP 16) all is fine. If i make a call with plugged in headphones - all is fine. If i unplug the headphones during the call - whole audio just stop working. If i hang up the call, make the call again - audio is there with no problems. On iPhone and iPad work correctly. Where can be a problem?
