Answer 1

if you have to work on touch-begain or node action , Then use it:

override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!) {
        let touch = touches.anyObject() as UITouch
        if CGRectContainsPoint(btncloseJump.frame, touch.locationInNode(self)) {
            self.scene.removeFromParent()
            btncloseJump.removeFromParent()
            let skView = self.view as SKView
            skView.ignoresSiblingOrder = true
            var scene: HomeScene!
            scene = HomeScene(size: skView.bounds.size)
            scene.scaleMode = .AspectFill
            skView.presentScene(scene, transition: SKTransition.fadeWithColor(SKColor(red: 25.0/255.0, green: 55.0/255.0, blue: 12.0/255.0, alpha: 1), duration: 1.0))
        }
    }

To start with your second question, it's kind of up to you. If you wish to, you can continue to follow the Objective-C convention of having one class per file, although this isn't a requirement, and wasn't in Objective-C either. That being said, if you have a couple of classes that are tightly related, but aren't made up of much code, it wouldn't be unreasonable to have them grouped in a single file. Just do what feels right, and don't make a huge blob of code in a single file.

Then for your first questions... Yes, you had a good deal of it already. Basically, from where you got up to, you need to create the instance of GameScene through its size: initializer. From there, you just set the properties and call present.

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    super.touchesBegan(touches, withEvent: event)

    guard let location = touches.first?.locationInNode(self),
        let scene = scene,
        nodeAtPoint(location) == "Game Button" else {
        return
    }

    let transition = SKTransition.reveal(
        with: .down, 
        duration: 1.0
    )

    let nextScene = GameScene(size: scene.size)
    nextScene.scaleMode = .aspectFill

    scene.view?.presentScene(nextScene, transition: transition)
}
