iOS 12 Lock screen controls for music app

In iOS 11 my music app would show the lock screen controls when I locked my iPhone. I was able to see the currently playing song and play/pause skip forward and backwards. However in upgrading to Xcode 10/iOS 12 I can no longer see the lock screen controls just the date and time...

However, if I swipe up and get that widget screen (where you can turn on airplane mode etc) I CAN see the now playing info.

Here is what I have

In the Background Modes

I have updated my code to the following:

Called in my viewDidLoad

do {
  try AVAudioSession.sharedInstance().setCategory(.soloAmbient, mode: .default, options: .allowAirPlay)
print("Playback OK")
  try AVAudioSession.sharedInstance().setActive(true)
  print("Session is Active")
} catch {
  print(error)
}


UIApplication.shared.beginReceivingRemoteControlEvents()
self.becomeFirstResponder()

I did not previously have the following code in the last working version but I added it because I found similar posts suggesting I do it

if let songInfo = self.mediaPlayer.nowPlayingItem {
  nowPlayingInfoCenter.nowPlayingInfo = [
    MPMediaItemPropertyTitle: songInfo.title ?? "",
    MPMediaItemPropertyArtist: songInfo.artist ?? "",
    MPMediaItemPropertyArtwork : songInfo.artwork?.image(at: CGSize(width: 400, height: 400)) ?? #imageLiteral(resourceName: "emptyArtworkImage")]
}

I put breakpoints on the do try it does not print either of the print functions and skips the try

Did I convert my code wrong?
