I am trying to set up my game and I can't please help

in the gameViewController there is an error showing for this line
let skView = view as! SKView it is saying Expected ‘)’ in expression list. What does that mean?

here is my setup

import UIKit
import SpriteKit

class GameViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    let scene = GameScene(size:CGSize(width: 1536, height: 2048)
    let skView = view as! SKView
    skView.showsFPS = true
    skView.showsNodeCount = true
    skView.ignoresSiblingOrder = true
    scene.scaleMode = .aspectFill
    skView.presentScene(scene)
}

override var prefersStatusBarHidden: Bool {
    return true
}

}

var supportedInterfaceOrientation: UIInterfaceOrientationMask {
return .portrait
}

Error messages don’t always identify the exact line with the problem. Check the previous line (let scene = …).
That is the statement that needs the closing parenthesis.

Have fun!

I figured it out in a different way. But thanks for the reply.
