How To Make Play/Pause Button on Apple TV Remote Play/Pause AVAudioPlayer - swift

Question

I am making a music app for tvOS which has a AVAudioPlayer. I was wondering how to make the Play/Pause Button on Apple TV remote Play/Pause the AVAudioPlayer? Here's my current code:
import UIKit
import AVFoundation
class MusicViewController: UIViewController, AVAudioPlayerDelegate {
#IBOutlet weak var progressView: UIProgressView!
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
do {
audioPlayer = try AVAudioPlayer(contentsOf: URL.init(fileURLWithPath: Bundle.main.path(forResource: "Roots", ofType: "mp3")!))
audioPlayer.prepareToPlay()
var audioSession = AVAudioSession.sharedInstance()
Timer.scheduledTimer(timeInterval: 0.01, target: self, selector: #selector(updateAudioProgressView), userInfo: nil, repeats: true)
progressView.setProgress(Float(audioPlayer.currentTime/audioPlayer.duration), animated: false)
do {
try audioSession.setCategory(AVAudioSessionCategoryPlayback)
}
}
catch {
print(error)
}
audioPlayer.delegate = self
}
// Set the music to automaticly play and stop
override func viewDidAppear(_ animated: Bool) {
audioPlayer.play()
}
override func viewDidDisappear(_ animated: Bool) {
audioPlayer.stop()
}
func updateAudioProgressView()
{
if audioPlayer.isPlaying
{
// Update progress
progressView.setProgress(Float(audioPlayer.currentTime/audioPlayer.duration), animated: true)
}
}
}
I've been looking arround trying to figure this out. I haven't worked with tvOS before, so this is new for me. Thanks so much for the help!

These functions have been working for us. They add a gesture recognizer that listens for the play/pause button on the remote. You can add this to your app delegate.
func initializePlayButtonRecognition() {
addPlayButtonRecognizer(#selector(AppDelegate.handlePlayButton(_:)))
}
func addPlayButtonRecognizer(_ selector: Selector) {
let playButtonRecognizer = UITapGestureRecognizer(target: self, action:selector)
playButtonRecognizer.allowedPressTypes = [NSNumber(value: UIPressType.playPause.rawValue as Int)]
self.window?.addGestureRecognizer(playButtonRecognizer)
}
func handlePlayButton(_ sender: AnyObject) {
if audioPlayer.isPlaying {
audioPlayer.pause() {
} else {
audioPlayer.play()
}
}
