I am also seeing this on macOS 12.0.1: [aqme]        MEMixerChannel.cpp:1639  client <AudioQueueObject@0x1240e0c00; Unknown FigPlayer; [0]; play> got error 2003332927 while sending format information After: CMTime newTime = CMTimeMakeWithSeconds(time, 600); [self.player seekToTime:newTime completionHandler:^(BOOL finished) { // optional debug logging if not finished }]; Using either .mp3 or .mp4 files. Each time I use a slider or 'go forward' or 'go backward' buttons to adjust playback location, these messages pop up on the Xcode debug console.

More info: I built a very basic test app from Xcode templates; it loads into the iPhone, and Xcode attaches to it successfully and enables debugging. So there is something my app is doing that prevents Xcode from attaching to it. My app: supports carplay plays audio does not use storyboard, except for Launch storyboard uses split view navigation any suggestions or thoughts would be welcome.

Thank you for the reply. get-task-allow was false. I realized that my profile needs to be a development profile, not a distribution profile. That must have been the reason get-task-allow was false. I can't set it to true otherwise.
