無法實例化名爲SCNView的類

我在嘗試啓動我的應用程序時遇到此錯誤。我的應用應該只是一個空的SKScene。根據我的理解，這通常是由於沒有導入適當的框架造成的。我已經連接了我的UIKit和SpriteKit框架，而這些是我使用的唯一兩個框架。無法實例化名爲SCNView的類

以下是我的ViewController代碼：

import UIKit 
import SpriteKit 

class GameViewController: UIViewController { 

    var scene: GameScene! 


    override func viewDidLoad() { 
     super.viewDidLoad() 

     // Configure the view 
     let skView = view as SKView 
     skView.multipleTouchEnabled = false 

     //Create and configure the scene 
     scene = GameScene(size: skView.bounds.size) 
     scene.scaleMode = .AspectFill 

     // Present the scene. 
     skView.presentScene(scene) 

    } 

    override func prefersStatusBarHidden() -> Bool { 
     return true 
    } 


    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Release any cached data, images, etc that aren't in use. 
    } 

}

以下是我的GameScene代碼：

import UIKit 
import SpriteKit 



let HurdleSize:CGFloat = 20.0 
let TickLengthLevelOne = NSTimeInterval(600) 

class GameScene: SKScene { 
    var tick: (() ->())? 
    var tickLengthMillis = TickLengthLevelOne 
    var lastTick:NSDate? 

    var textureCache = Dictionary<String, SKTexture>() 

    override init(size: CGSize) { 
     super.init(size: size) 
    } 

    required init?(coder aDecoder: NSCoder) { 
     fatalError("init(coder:) has not been implemented") 
    } 
}

和下面是我的錯誤跟蹤：
