如何从视图控制器移动到skscene

import SpriteKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let skView = SKView(frame: view.bounds)
        view.addSubview(skView)
    }
}

import SpriteKit

class GameScene: SKScene {
    // 在这里实现你的场景逻辑
}

import SpriteKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let skView = SKView(frame: view.bounds)
        view.addSubview(skView)
        
        let gameScene = GameScene(size: skView.bounds.size)
        skView.presentScene(gameScene)
    }
}
