ios - SpriteKit View not presenting Scene in ViewController's viewDidLoad -

goal: red rectangle (of class brick) should appear in blue background node count , fps.

reality: gray background , node count , fps (e.g. no red rectangle or blue background)

i have following code:

gameviewcontroller

import spritekit  class gameviewcontroller: uiviewcontroller {      override func loadview() {         self.view = skview(frame: uiscreen.mainscreen().bounds)     }      override func viewdidload() {         super.viewdidload()          let scene: gamescene = gamescene()          let viewasskview = self.view as! skview         viewasskview.showsfps = true         viewasskview.showsnodecount = true         viewasskview.backgroundcolor = uicolor.bluecolor()          viewasskview.presentscene(scene)     } } 

my best guess something's wrong gameviewcontroller, i'm not sure what. viewdidload() must've been called because fps , node count.

gamescene

class gamescene: skscene {      override func didmovetoview(view: skview) {          let mybrick = brick()         mybrick.position = cgpointmake(100, 100)         self.addchild(mybrick)      }  } 

by lack of complexity, assume nothing wrong gamescene.

appdelegate

import uikit  @uiapplicationmain class appdelegate: uiresponder, uiapplicationdelegate {      var window: uiwindow?       func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {         self.window = uiwindow(frame: uiscreen.mainscreen().bounds)         self.window!.backgroundcolor = uicolor.orangecolor()                self.window!.rootviewcontroller = gameviewcontroller()         self.window!.makekeyandvisible()          return true     } 

i know nothing wrong appdelegate, because if changed self.window!.rootviewcontroller uiviewcontroller, orange screen.

your scene has no size. can set size programmatically initializing scene using size initializer.

let scene: gamescene = gamescene(size:view.bounds.size) 

or set scene's scale mode resizefill size of scene resize match skview's size:

scene.scalemode = skscenescalemode.resizefill
