SpriteKit hasn’t gotten much love from Apple after it was created, but it was pretty complete already. I’m not a fan of the sks files or storyboards so I’ve created a starting project where you can just start coding on a 2d game.

https://github.com/mevdev/SimpleSpriteKit

Features:

• No sample code
• Programmatic invocation of starting view controller, which eliminates the need for a storyboard.
• GameScene is programmatically invoked, which eliminated the (useless to me) sks file
