Some iPhone 7 plus (and only these device models) are throwing an error

Code Block 	let audioDevice	= AVCaptureDevice.default(for: AVMediaType.audio)
	 if audioDevice == nil {
					showError("Nil Audio Device")
	 }

I need to understand under what circumstances could this be nil? Assuming user gave permission for Microphone.

I also tried AVCaptureDiscoverSession

Code Block 	     private var audioDiscoverySession = AVCaptureDevice.DiscoverySession(deviceTypes: [AVCaptureDevice.DeviceType.builtInMicrophone], mediaType: .audio, position: .unspecified)

And tried to grab the first device. Still, it is nil. Why?
