An SKScene object represents a scene of content in Sprite Kit. A scene is the root node in a tree of Sprite Kit nodes (SKNode). These nodes provide content that the scene animates and renders for display. To display a scene, you present it from an SKView object. SKScene is Apple technology for use on iOS 7.0 and later.

An SKScene object represents a scene of content in Sprite Kit. A scene is the root node in a tree of Sprite Kit nodes (SKNode). These nodes provide content that the scene animates and renders for display. To display a scene, you present it from an SKView object.

A scene calculates the contents of a new frame by processing the following actions in order:

  • The scene calls its update: method.
  • The scene executes actions on its children.
  • The scene calls its didEvaluateActions method.
  • The scene executes any physics simulations on physics bodies in the scene.
  • The scene calls its didSimulatePhysics method.

SKView.presentScene with transition not working if have shown another SKView

Update - see my own answer, it was a retain cycle with very indirect results. I have a very weird bug apparently as some kind of side-effect of having shown an SKView in a different UIView. It seems a manifestation of the old iOS9 bug presentScene…

I have asked this similar question a while ago, but since then it seems SKNode now has this nifty initializer init?(fileNamed filename: String) that unarchives the scene from an .sks file. The thing is, this initializer is on SKNode, not SKScene,…
