Control video playback with keyboard controls

For a macOS app to show up in the Now Playing media center (which enables media keys [F7, F8, F9]) you just need to configure the MPNowPlayingInfoCenter’s playbackState

func play() {
  self.player.play()
  MPNowPlayingInfoCenter.default().playbackState = .playing
}

And then subscribe to RemoteCommand changes:

let commandCenter = MPRemoteCommandCenter.shared()
commandCenter.pauseCommand.addTarget { (event) -> MPRemoteCommandHandlerStatus in
  self.player.pause()
  MPNowPlayingInfoCenter.default().playbackState = .paused
  return .success
}
commandCenter.playCommand.addTarget { (event) -> MPRemoteCommandHandlerStatus in
  self.player.play()
  MPNowPlayingInfoCenter.default().playbackState = .playing
  return .success
}
