How Do I Get Audio Controls on Lock Screen/Control Center from AVAudioPlayer in Swift

You need to invoke beginReceivingRemoteControlEvents() otherwise it will not work on the actual device.

Swift 3.1

UIApplication.shared.beginReceivingRemoteControlEvents()

If you would like to specify custom actions for the MPRemoteCommandCenter:

let commandCenter = MPRemoteCommandCenter.shared()commandCenter.nextTrackCommand.isEnabled = truecommandCenter.nextTrackCommand.addTarget(self, action:#selector(nextTrackCommandSelector))

To implement this functionality, use the Media Player framework’s MPRemoteCommandCenter and MPNowPlayingInfoCenter classes with AVPlayer.

import MediaPlayerimport AVFoundation// Configure AVPlayervar player = AVPlayer()

Configure the Remote Command Handlers

Defines a variety of commands in the form of MPRemoteCommand objects to which you can attach custom event handlers to control playback in your app.

    func setupRemoteTransportControls() {    // Get the shared MPRemoteCommandCenter    let commandCenter = MPRemoteCommandCenter.shared()    // Add handler for Play Command    commandCenter.playCommand.addTarget { [unowned self] event in        if self.player.rate == 0.0 {            self.player.play()            return .success        }        return .commandFailed    }    // Add handler for Pause Command    commandCenter.pauseCommand.addTarget { [unowned self] event in        if self.player.rate == 1.0 {            self.player.pause()            return .success        }        return .commandFailed    }}

Provide Display Metadata

Provide a dictionary of metadata using the keys defined by MPMediaItem and MPNowPlayingInfoCenter and set that dictionary on the default instance of MPNowPlayingInfoCenter.

func setupNowPlaying() {    // Define Now Playing Info    var nowPlayingInfo = [String : Any]()    nowPlayingInfo[MPMediaItemPropertyTitle] = "My Movie"    if let image = UIImage(named: "lockscreen") {        nowPlayingInfo[MPMediaItemPropertyArtwork] =            MPMediaItemArtwork(boundsSize: image.size) { size in                return image        }    }    nowPlayingInfo[MPNowPlayingInfoPropertyElapsedPlaybackTime] = playerItem.currentTime().seconds    nowPlayingInfo[MPMediaItemPropertyPlaybackDuration] = playerItem.asset.duration.seconds    nowPlayingInfo[MPNowPlayingInfoPropertyPlaybackRate] = player.rate    // Set the metadata    MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlayingInfo}
