How to set the scalemode of a scene when I transit into it?

Question

My problem is when I am trying to switch to a scene, the view of it is different when it was my start scene.

The problem is -I think- the scale mode, so I tried to set the scale mode but it didn't work. This what I have tried:

let skView = self.view! as SKView

let gameScene:GameScene = GameScene(size: self.frame.size)
gameScene.size = skView.bounds.size
gameScene.scaleMode = SKSceneScaleMode.ResizeFill

skView.presentScene(gameScene , transition: SKTransition.crossFadeWithDuration(1))

And this:

let gameScene = GameScene(size: self.size)

gameScene.scaleMode = SKSceneScaleMode.ResizeFill

self.view?.scene!.presentScene(gameScene , transition: SKTransition.crossFadeWithDuration(1))

And I have tried to set the scale mode of the scene in the didMoveToView() function.

None of these methods helps, any help?

Here's an example to transition from one scene to another. Supposed GameMenu is your first scene and you want to transition to GameScene.

In GameViewController initialize GameMenu size:

override func viewDidLoad() {
    super.viewDidLoad()

    let scene = GameMenu(size: view.bounds.size)
    // Configure the view.
    let skView = self.view as! SKView
    skView.showsFPS = true
    skView.showsNodeCount = true

    /* Sprite Kit applies additional optimizations to improve rendering performance */
    skView.ignoresSiblingOrder = true

    /* Set the scale mode to scale to fit the window */
    scene.scaleMode = .AspectFill

    skView.presentScene(scene)
}

Now, you should be at the first scene. When to transition to GameScene, add the following code as needed:

let nextScene = GameScene(size: self.size)
scene?.view?.presentScene(nextScene, transition: SKTransition.crossFadeWithDuration(1))

And now everything's done and GameScene appears. Check this sample project if you have any problem.
