Next and previous default video controls with AVPlayerViewController - AVQueuePlayer not working

I have a list of songs to play in an AVPlayerViewController, so I am using AVQueuePlayer to play it. All songs are stored in the kit.

Now on the default screen I get the following functions:

• Play / Pause
• Automatically switch to the next video after completing the previous one
• Fast forward the current video ('→ |')
• Fast backward current video ('| <<')

What is not required should :

• Previous functionality with provided '| <<to go to the previous video.
• The following functionality with the provided "→ |" to go to the next video.

This I have done so far -

var arrAVPlayerItems = [AVPlayerItem]()
     for i in 1...4 {
         let fileURL = Bundle.main.url(forResource: "sample-\(i)", withExtension: "mp4")
         arrAVPlayerItems.append(AVPlayerItem(url: fileURL!))
     }
     let player = AVQueuePlayer(items: arrAVPlayerItems)
     playerViewController = AVPlayerViewController()
     playerViewController.player = player
     playerViewController.showsPlaybackControls = true

      

        
        
        
      

    

The situation here is that I will only have to use the default controls and not create my own.
Thanks in advance.
