iOS 12+ and Swift 4+

Following is an improved way of handling scrubbing in Remote Play Center:

// Handle remote events
func setupRemoteTransportControls() {
    let commandCenter = MPRemoteCommandCenter.shared()

    // Scrubber
    commandCenter.changePlaybackPositionCommand.addTarget { [weak self](remoteEvent) -> MPRemoteCommandHandlerStatus in
        guard let self = self else {return .commandFailed}
        if let player = self.player {
           let playerRate = player.rate
           if let event = remoteEvent as? MPChangePlaybackPositionCommandEvent {
               player.seek(to: CMTime(seconds: event.positionTime, preferredTimescale: CMTimeScale(1000)), completionHandler: { [weak self](success) in
                   guard let self = self else {return}
                   if success {
                       self.player?.rate = playerRate
                   }
               })
               return .success
            }
        }
        return .commandFailed
    }

    // Register to receive events
    UIApplication.shared.beginReceivingRemoteControlEvents()
}
