I am creating a 2D SpriteKit game in Swift which will have many levels. I want to use multiple .sks files to design each of those levels, but I can't figure out how to link multiple .sks files to one .swift "gamePlay" file. I would also use a .sks file to create the "main menu," which would be a separate .swift "mainMenu" file.
I have looked at the stack overflow post on connecting .sks files to .swift files, but the post only addresses working through the appDelegate and appears to only allow one connection to one .sks file.
I am new to Swift and any help would be much appreciated.
