App getting crashed after updating OS version to OS 15.1 at the time of first time launch, and after crash it works fine. In earlier version like in 15.0 it was working fine. While Debug I found in the first time in audio video permission app getting stuck in below code.
if ([AVCaptureDevice respondsToSelector:@selector(requestAccessForMediaType: completionHandler:)]) { [AVCaptureDevice requestAccessForMediaType:AVMediaTypeAudio completionHandler:^(BOOL granted) { if (granted) { dispatch_async(dispatch_get_main_queue(), ^{ }); } else { } }]; } else { }
