Select the iOS device or bluetooth audio output with action sheet

While playing a sound file with AVAudioPlayer, the following code may be used to select the audio output between the speaker of an iPhone/iPad or the bluetooth headset in an action sheet:

let buttonOutput = UIButton(frame: CGRectMake(0, 0, 200, 30))

buttonOutput.center = CGPointMake(view.center.x, view.center.y+200)

buttonOutput.setTitle("Output", forState: UIControlState.Normal)

buttonOutput.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal)

buttonOutput.setTitleColor(UIColor.cyanColor(), forState: UIControlState.Highlighted)

buttonOutput.addTarget(self, action: #selector(buttonOutputPressed), forControlEvents: UIControlEvents.TouchUpInside)

view.addSubview(buttonOutput)

and

func buttonOutputPressed() {

        

    let model = UIDevice.currentDevice().model

        

    let session = AVAudioSession()

        

    let controller = UIAlertController(title: "Select Output", message: "", preferredStyle: UIAlertControllerStyle.ActionSheet)

        controller.addAction(UIAlertAction(title: model, style: UIAlertActionStyle.Default, handler: { action in

    do {

        try session.setCategory(AVAudioSessionCategoryPlayAndRecord, withOptions: AVAudioSessionCategoryOptions.DefaultToSpeaker)

    } catch {

        print("AVAudioSession error!")

    }

    }))

    controller.addAction(UIAlertAction(title: "Bluetooth", style: UIAlertActionStyle.Default, handler: { action in

    do {

        try session.setCategory(AVAudioSessionCategoryPlayAndRecord, withOptions: AVAudioSessionCategoryOptions.AllowBluetooth)

    } catch {

        print("AVAudioSession error!")

    }

    }))

    presentViewController(controller, animated: true, completion: nil)

}

Result:
