DeviceInfo.isHeadphonesConnected() doesn't detect all ways headphones can be connected on iOS

Summary

The current code for iOS, I think, doesn't cover some cases for wired headphones

So I have some BT headphones that I can also connect via an cable and adapter to a lightning port; I believe if you check for line-in you will pick up some more use cases ,but these of course, aren't guaranteed to be headphones per se. Below is a code snippet that you could use to adjust the existing code for this if you wanted. - thank you Apple for the confusion.

if ([[port portType] isEqualToString:AVAudioSessionPortHeadphones] ||
            [[port portType] isEqualToString:AVAudioSessionPortAudioUSB] ||   // strictly speaking not headphones, but might be
            [[port portType] isEqualToString:AVAudioSessionPortBluetoothA2DP] ||
            [[port portType] isEqualToString:AVAudioSessionPortBluetoothHFP] ||
            [[port portType] isEqualToString:AVAudioSessionPortBluetoothLE]) {
            return YES;
        }
    }
return NO;

Hi there! If you proposed a PR we could merge it. Note the code you mention needs a modification is now duplicated, so there's two spots to add the different bluetooth profiles
