We have and app that is using UITextView.layoutManager quite a lot. Does that means that in next version of iOS, when TextKit2.0 is available for UITextView, we will have to update the app? Will old, not updated app on AppStore still work without updates? What are the reasons it is not available on iOS15? P.S. TextKit1.0 in AppKit have a lot more functionality than UIKit version. Would be great to have feature parity. With ARM CPU in both Macs and iPads there is no reason not to.

I want to configure AVAudioSession that I can record video with audio and also play music from Music app (or any other app that is producing sound, typically internet radios apps)I configure session like this:try? AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord, with: .mixWithOthers)try? AVAudioSession.sharedInstance().setActive(true, with: .notifyOthersOnDeactivation)This works the way that when my recording app is running I can start playing audio from music app and record video (also record audio as well). So far good.Now, I put my recording app to the background. Music app continues to play. It is fine. But, when my app is coming back from background music app stop its playback. I would like it to continue. So it basically behaves as build in camera app when shooting video. Is there a way to tell the system that I want other app to continue playback?
