Whats the correct way, using “init” or “didmove”?

问题:

Language: Swift 3.0 --- IDE : Xcode 8.0 beta 2 --- Project : iOS Game (SpriteKit)

I create a game for iOS and i know Apple is really strict with their rules to accept the app/game. So i want to know which is the correct way to setup a game.

I learned from google to create a new SpriteKit Project and do the following setup :

In GameViewController.swift clear viewDidLoad() and add all this :

override func viewDidLoad() {     super.viewDidLoad()     let skView = self.view as! SKView      let scene = GameScene(size: skView.bounds.size)     scene.scaleMode = .aspectFit      skView.presentScene(scene) } 

In GameScene.swift delete everything and leave this code :

import SpriteKit  class GameScene: SKScene {     required init?(coder aDecoder: NSCoder) {         super.init(coder: aDecoder)     }      override init(size: CGSize) {         super.init(size: size)         // add all the code of the game here...     }  } 

and develop my game inside override init

But I think thats actually wrong to start the game with init. And that the right way is to use the didMove() method. So should the code be written inside here? :

override func didMove(to view: SKView) {     <#code#> } 

Does anyone know which one is the correct way? And why? Also if its wrong the way i do it, can you explain me how to use didMove method?

Don't know if this is a silly question just bothered me that using init is wrong and wanted to ask if someone knows more about this.

Overriding the SKScene init

You can override the initializers of SKScene like described by @Knight0fDragon

class GameScene : SKScene {      required init?(coder aDecoder: NSCoder) {         super.init(coder: aDecoder)         setup()                  }      override init() {         super.init()         setup()     }      override init(size: CGSize) {         super.init(size: size)         setup()     }      func setup()     {         // PUT YOUR CODE HERE      } } 

Or you can use the didMove(to:)

class GameScene: SKScene {     override func didMove(to view: SKView) {         super.didMove(to: view)         // PUT YOUR CODE HERE <-----     } } 

The init is called only when the scene is initialised. The didMove is called when the scene is presented into the view.
