how to scale the window to fit in all devices?

I want to know how can I scale the window to fit with the same size in all diveces. The problem is that in some diveces the objects doesnt cover the same space of how I want.

I have my scaleMode = .ResizeFill but the problem is that if I make it .AspectFill it doesnt appear in the correct place. I think that the problem is that I added a new container on the scene, but I dont know how to solve it.

class GameViewController: UIViewController {

override func viewDidLoad() {

if let scene = GameScene(fileNamed:"GameScene") {
// 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 = .ResizeFill
scene.position = view.center


override func didMoveToView(view: SKView) {
/* Setup your scene here */

scaleMode = .ResizeFill
node.position = view.center
// 3) Add the container to the scene
// 4) Set the sprite's x position
sprite.position = CGPointMake(radius, 0)
// 5) Add the sprite to the container
// 6) Rotate the container
sprite.color = UIColor.whiteColor()
sprite.colorBlendFactor = 1.0
sprite.zPosition = 4.0

circulo = SKSpriteNode(imageNamed: "circuloFondo2")
circulo.size = CGSize(width: 294, height: 294)
circulo.color = UIColor(red: 0.15, green: 0.15, blue: 0.15, alpha: 1)
circulo.colorBlendFactor = 1
circulo.alpha = 0.35
circulo.position = view.center
circulo.zPosition = 1

  • The issue might be in code where you draw circle,You might be drawing the circle with same radius for all screen sizes.
  • Instead of drawing the circle with the same radius, you need to provide dynamic radius of the circle according to the device width.

Replace this

circulo.size = CGSize(width: 294, height: 294)

Use following snippet

let padding:CGFloat =  40.0  
circulo.size = CGSize(width:view.frame.size.width - padding , height: view.frame.size.width - padding)
