import uikit import spritekit import avfoundation   var backgroundmusicplayer:avaudioplayer = avaudioplayer()  class gameviewcontroller: uiviewcontroller {   override func viewdidload() {     super.viewdidload()  }    override func viewwilllayoutsubviews() {        var skview:skview = self.view skview     skview.showsfps = true     skview.showsnodecount = true     skview.showsphysics = true        var scene:skscene = gamescene.scenewithsize(skview.bounds.size)     scene.scalemode = skscenescalemode.aspectfill     skview.presentscene(scene)      var bgmusicurl:nsurl = nsbundle.mainbundle().urlforresource("fond", withextension: "mp3")!     backgroundmusicplayer = avaudioplayer(contentsofurl: bgmusicurl, error:nil)     backgroundmusicplayer.numberofloops = -1     backgroundmusicplayer.preparetoplay()     backgroundmusicplayer.play()   }  override func shouldautorotate() -> bool {     return true }  override func supportedinterfaceorientations() -> int {     if uidevice.currentdevice().userinterfaceidiom == .phone {         return int(uiinterfaceorientationmask.allbutupsidedown.toraw())     } else {         return int(uiinterfaceorientationmask.all.toraw())     } }   override func didreceivememorywarning() {     super.didreceivememorywarning()     // release cached data, images, etc aren't in use. }  override func prefersstatusbarhidden() -> bool {     return true } 

}

thank you

let gamescene = gamescene(size: skview.bounds.size)         gamescene.scalemode = .aspectfill         skview.presentscene(gamescene)   instead of      var scene:skscene = gamescene.scenewithsize(skview.bounds.size)     scene.scalemode = skscenescalemode.aspectfill     skview.presentscene(scene)
