In which case audioSession.currentRoute.outputs empty?
I have a mobile application. It has some play audio. It works fine my devices always, but I receive many crashes from real users in Crashlytic. Simply, my code is:
- (void) checkAndResetAudioSession {
.
.
AVAudioSession * audioSession = [AVAudioSession sharedInstance];
.
.
AVAudioSessionPortDescription * outputPort = [audioSession.currentRoute.outputs objectAtIndex:0];
.
}
I get crashes which says:
Fatal Exception: NSRangeException
0 CoreFoundation 0x106eb3ea0 __exceptionPreprocess
1 libobjc.A.dylib 0x106085a40 objc_exception_throw
2 CoreFoundation 0x106dc5a90 -[__NSCFArray count]
3 MyApp 0x303b235e4 -[AudioSessionManager checkAndResetAudioSession] (AudioSessionManager.mm:100)
.
.
As I understand, it crashes because of it tries to reach 0th index object of audioSession.currentRoute.outputs variable. That means, output should be empty. In which case, audioSession.currentRoute.outputs can be empty? As I understand, it is output devices. So, at least there should be always one output device.
Additional information, as I see, this problem happens almost always in iOS 12 and mostly iPhone X, 7 and 7 plus (%50 crashes come from these 3 devices).

Did you check what happens when you have a bluetooth speaker connected and you move the phone out of range?
