SKView please presentScene(nil) or the scene will still here and eat the memory

me design LevelViewController (TableView) -> present -> GameViewController . SKView . Scene

When I dismiss the GameViewController, the scene “update” (onEnterFrame) still running, to prove that the scene has not been killed

And after several time present the GameViewController, the app will lag becoz too many SKScene is running.

So please (self.view as! SKView).presentScene(nil) when GameViewController self.dismissViewControllerAnimated(true, completion: nil)
