This Swift w/ SpriteKit code does not do what is intended - ios

Question

I am very new to Swift and iOS development. I was watching tutorials on iOS development w/ Swift and SpriteKit. Following the tutorials I opened Xcode, new project, game, universal; and all I changed was the GameScene.swift. Here is the new code:
import SpriteKit
class GameScene: SKScene {
override func didMoveToView(view: SKView) {
/* Setup your scene here */
var node1 = SKNode()
node1.position = CGPoint(x: 100, y: 100)
self.addChild(node1)
var spr1 = SKSpriteNode(imageNamed: "Spaceship")
spr1.position = CGPointZero
spr1.zPosition = 1
node1.addChild(spr1)
}
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
/* Called when a touch begins */
}
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
}
}
Note: the Spaceship image is provided by default.
So in the tutorials, this code added a spaceship to the scene. However, when I run the simulator, the scene remains blank. What can be the problem? If more info is needed, please say so and I will provide.

Answer 1

It could be running correctly, and you just can't see it on the screen. Depending on the device that you're emulating, you may be showing the spaceship off screen. Try a different, smaller device, to emulate, and check if you can see it.

Answer 2

Try going into your GameViewController.swift and making sure that you see something along the lines of this:
class GameViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
if let scene = GameScene(fileNamed:"GameScene") {
let skView = self.view as! SKView
skView.showsFPS = true
skView.showsNodeCount = true
skView.ignoresSiblingOrder = true
scene.scaleMode = .AspectFill
scene.size = skView.bounds.size
skView.presentScene(scene)
}
}
}
