I am new to SpriteKit and Swift and am looking for some advice. I am creating a simple level based game that progressively gets harder each level. Each level has a different layout and obstacles. I have a GameScene.swift file and GameScene.sks file. The game works but I am unclear on what is the proper way to handle additional levels. I am planning on making 50 levels. Do I need to create a swift and sks file for each level? Or is there a more efficient and proper way of handling this? Any advice is appreciated!
