The Project Setup

The easiest way to set up the project is to create a new Game App.

Go to Xcode > File > New > Project > Game. Name your project whatever you want.

Open up the GameScene.swift file and delete everything until it looks like this:

import SpriteKit
import GameplayKit
class GameScene: SKScene {
    override func didMove(to view: SKView) {
    }
    
    override func update(_ currentTime: TimeInterval) {
        // Called before each frame is rendered
    }
}

Then go to a file called GameScene.sks and remove the hello label. Now, if you run the app you should only see a blank screen which means you’re good to go.
