Currently, I'm using an SKS file to set up my sprite locations via empty nodes or in some instances I am actually dragging and dropping the sprite into the scene editor. After having some loading issues, I was advised to preload all of the textures via a texture atlas. One issue that I came across before moving to this scheme was that my didMoveToView method was using more and more memory every time a scene loaded and reloaded. I have 3 scenes in my SpriteKit game: a main menu, level select and level scene. How should my scenes be managed? Should I create an instance of each and store them globally to avoid using too much memory? Currently, each scene is capable of initializing and calling presentScene. With my level scene there's a good amount of setup that needs to be done and when loading from the level selection scene I'm not sure if this should be recreated over and over again. I hope this is clear as to what I'm asking. Thanks in advance.

SK does all of its memory management and caching behind the scenes. You really have no control over any of it. Short of your code having a memory leak or retain cycle somewhere, your app's memory usage will top out at a certain point.
If you want, you can manually 'nil out' all scene objects and [self removeAllChildren]; in the -(void)willMoveFromView:(SKView *)view method.
