SKNodes don't show in scene

Question

I had scene set up and everything worked well. It looked like this:

But the controller was set up in Main.storyboard and I wanted to get rid of it. So I did something like this:

    window = UIWindow(frame: UIScreen.main.bounds)
    window?.makeKeyAndVisible()
    window?.rootViewController = GameViewController()

in appDelegate and this:

override func loadView() {
    super.loadView()
    self.view = SKView()
}

in GameViewController to load it. First time, the scene loaded, but only the green background, no other nodes. (Node counter showed the correct number of nodes.)

So I tried setting the ignoresSiblingOrder both true and false, all options of scene.scaleMode and the best result that I achieved was with scene.scaleMode = .resizeFill. Looked like this:

EDIT: Position for circles:

greenOne.position = CGPoint(x: greenOne.radius + sticksOffset, y: greenOne.radius + sticksOffset)
redOne.position = CGPoint(x: self.frame.maxX - redOne.radius - sticksOffset / 2, y: view.bounds.size.height / 2)

Tried this and redOne appeared next to the green

redOne.position = CGPoint(x: redOne.radius + 100, y: 200)

It seems that the view didn't fit the screen and is just too large.

Answer 1

Solved by changing view init in GameViewController:

override func loadView() {
    super.loadView()

    self.view = SKView(frame: UIScreen.main.applicationFrame)
}

The old version of view had zero width and height, so the GameScene didn't get any dimensions.
