Rather than using the UIEvent stream with remoteControlReceivedWithEvent, I would recommend you use MPRemoteCommandCenter to control the previous/next/play/pause actions on the lock screen and control center.

import MediaPlayer

// ...

let commandCenter = MPRemoteCommandCenter.sharedCommandCenter()

commandCenter.previousTrackCommand.enabled = true;
commandCenter.previousTrackCommand.addTarget(self, action: "previousTrack")

commandCenter.nextTrackCommand.enabled = true
commandCenter.nextTrackCommand.addTarget(self, action: "nextTrack")

commandCenter.playCommand.enabled = true
commandCenter.playCommand.addTarget(self, action: "playAudio")

commandCenter.pauseCommand.enabled = true
commandCenter.pauseCommand.addTarget(self, action: "pauseAudio")

Where previousTrack, nextTrack, playAudio, and pauseAudio are all functions in your class where you control the player.

You may need to explicitly disable the skip forward and backward commands as well:

commandCenter.skipBackwardCommand.enabled = false
commandCenter.skipForwardCommand.enabled = false
