Discussion
SceneKit calls this method exactly once per frame, so long as the SCNView object (or other SCNScene object) displaying the scene is not paused.
Implement this method to add game logic to the rendering loop. Any changes you make to the scene graph during this method are immediately reflected in the displayed scene. That is, SceneKit immediately updates the hierarchy of presentation nodes it uses to render the scene (instead of using the SCNTransaction class to “batch” your changes).
