TL; DR: I made a Mac app that asks you a bunch of questions about your game and then tells you how to set up your SpriteKit scene and asset documents.
Update: I would say this method is still valid if you want to use single assets across all devices, but I am now using points and asset catalogs (even though it’s a lot of extra work).
I honestly thought I had it figured out.
I mean, I had. Except it’s always more complicated than that.
Let’s talk about scene sizes.
