pressesBegan not called in Playground Book

Question

I need to respond to keys being pressed on a physical keyboard, but the method pressesBegan is not being called on any class. I've tried putting it inside my SKScene and my ViewController, but it just is not getting recognized

UPDATE Here is the code, I've replaced the logic with fatalError(), so that the book will crash when pressesBegan gets called. Since it's not crashing, pressesBegan is not being called

The rest of the code has nothing related to responders

import Foundation
import SpriteKit
import SceneKit
import UIKit

public class GameScene: SKScene {
    
  // ... some code
    
    public override func pressesBegan(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
        fatalError()
    }
    
    /// Some more code...
}


class GameViewController: UIViewController {
    
    override func loadView(){
        self.view = sceneView
    }

    let sceneView = SKView(frame: CGRect(x:0 , y:0, width: 1920, height: 1080))
    override func viewDidLoad() {
        if let scene = GameScene(fileNamed: "GameScene") {
            // Set the scale mode to scale to fit the window
            scene.scaleMode = .aspectFill
            
            // Present the scene
            sceneView.presentScene(scene)
        }
    }
    
    public override func pressesBegan(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
        fatalError()
    }
}

let viewController = GameViewController()
viewController.view.becomeFirstResponder()

PlaygroundPage.current.liveView = viewController
PlaygroundPage.current.needsIndefiniteExecution = true

Answer 1

Solved by adding override var canBecomeFirstResponder { true } to the UIViewController, calling myViewController.becomeFirstResponder() after presenting the controller and calling super.pressesBegan when I'm not handling the press
