Can AVPlayerViewController be customized via Storyboard or must it be done via adding subviews?

Question

I am using AVPlayerViewController/AVPlayer to play mp3s. I would like to be able to add an image and a textView when the player kicks off. I've sort of been able to do this by adding subviews but I can't get the textView to scroll. I was thinking that maybe I could just use Storyboard and drag an AVPlayerViewController into it and customize it there like a regular viewController ...but that doesn't seem possible because Xcode has crashed a few times when I've tried this. Is it even possible (or advisable) to try adding an imageView and/or textView via Storyboard somehow, or do I have to use subviews?

If it's subviews, how can I get my textView to scroll (I have another post asking about that)? The code that I have currently (without having AVPlayerViewController on the Storyboard) is:

let url = URL(string:mystream)
    let player = AVPlayer(url: url!)
    
    let controller = AVPlayerViewController()
    
    controller.player = player
    controller.view.frame = self.view.frame

    controller.contentOverlayView!.backgroundColor = UIColor(red: 148/255, green: 148/255, blue: 184/255, alpha: 1)
  
    //.. view
    var myView = UIView(frame: CGRect(x: 0, y: 0, width: view.bounds.width, height: view.bounds.height))

    //.. imageView
    var imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 325, height: 325))
    imageView.image = myImage
    imageView.contentMode = .scaleAspectFit
    imageView.translatesAutoresizingMaskIntoConstraints = false

    //.. textView
    var myTextView = UITextView(frame: CGRect(x: 0, y: 0, width: 350, height: 600))
    //myTextView.text = currentList
    myTextView.text = "Lorem ipsum dolor sit er elit lamet, consectetaur cillium adipisicing pecu, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

    myTextView.font = UIFont(name: "Chalkboard SE", size: 18)
    myTextView.textColor = UIColor.yellow
    myTextView.backgroundColor = UIColor.gray
    
    //..
    myTextView.contentMode = .scaleAspectFit
    
    myTextView.isScrollEnabled = true
    myTextView.isUserInteractionEnabled = true
    myTextView.isEditable = true
    myTextView.isSelectable = true
    myTextView.bounces = true
    myTextView.showsVerticalScrollIndicator = true
    myTextView.showsHorizontalScrollIndicator = true
    myTextView.contentSize = CGSize(width: 700, height: 700)
    
    myTextView.translatesAutoresizingMaskIntoConstraints = false
    
    myView.addSubview(imageView)
    myView.addSubview(myTextView)
    
    controller.contentOverlayView?.addSubview(myView)

    //.. @@@@@@@@@
    imageView.topAnchor.constraint(equalTo: myView.safeAreaLayoutGuide.topAnchor, constant: 50).isActive = true
    imageView.centerXAnchor.constraint(equalTo: myView.centerXAnchor, constant: 0).isActive = true
    imageView.widthAnchor.constraint(equalToConstant: 325).isActive = true
    imageView.heightAnchor.constraint(equalToConstant: 325).isActive = true

    myTextView.topAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 15).isActive = true
    myTextView.centerXAnchor.constraint(equalTo: myView.centerXAnchor, constant: 0).isActive = true
    myTextView.widthAnchor.constraint(equalToConstant: 325).isActive = true
    myTextView.heightAnchor.constraint(equalToConstant: 200).isActive = true
    
    //.. @@@@@@@@@
    
    present(controller, animated: true) {
            player.play()
    }

Here is what the current player presents as... I need to be able to scroll the text...

Fortunately these days it's now trivial to use AVPlayerViewController on storyboard ...

You will definitely want to use a container view.

(As with any container view, just add the one line of code to get the segue ... EXPLANATION if needed.)

(Note that, as with any time you click to add a container view, Xcode happens to make the new controller a plain UIViewController. Just click to change it to a AVPlayerViewController.) (EXPLANATION if needed.)

It's then easy to operate the AVPVC in code,

    var ezPlayer: AVPlayerViewController!
    ...

    ezPlayer.showsPlaybackControls = true
    ezPlayer.player = AVPlayer(url: u)

etc etc
