In the Project Navigator, select the GameViewController.swift file to open it in the Source Editor. Locate and review the viewDidLoad() method. It looks like this:

​ ​override​ ​func​ ​viewDidLoad​() {
​   ​super​.​viewDidLoad​()
​ 
​   ​// Load 'GameScene.sks' as a GKScene. This provides gameplay-related content​
​   ​// including entities and graphs​
​   ​if​ ​let​ scene = ​GKScene​(fileNamed: ​"GameScene"​) {
​ 
​     ​// Get the SKScene from the loaded GKScene​
​     ​if​ ​let​ sceneNode = scene.rootNode ​as!​ ​GameScene​? {
​ 
​       ​// Copy gameplay-related content over to the scene​
​       sceneNode.entities = scene.entities
​       sceneNode.graphs = scene.graphs
​ 
​       ​// Set the scale mode to scale to fit the window​
​       sceneNode.scaleMode = .aspectFill
​ 
​       ​// Present the scene​
​       ​if​ ​let​ view = ​self​.view ​as!​ ​SKView​? {
​         view.​presentScene​(sceneNode)
​ 
​         view.ignoresSiblingOrder = ​true​
​ 
​         view.showsFPS = ​true​
​         view.showsNodeCount = ​true​
​       }
​     }
​   }
​ }

Some of this code in this method may look a little familiar, such as the line that reads view.ignoresSiblingOrder = true. This code is what dictates, in part, how the scene renders. Change that line to read:
