How to use a sprite sheet in swift and sprite kit?

Title says it all. How do i use a sprite sheet in swift and sprite kit? I've searched google, stack exchange, and the apple documentation and I can't figure this one out.

In xcode 7, you can use Images.xcassets to create a sprite atlas.

1. Click on Images.xcassets
2. Click on the plus bottom in the bottom left
3. Select "new sprite atlas"
4. Then you can drag and drop all your images into the atlas

If you drag in all three image sizes with the proper suffix (@2x and @3x) it will automatically populate the images for you.

Then to use these assets in code simply write:

let atlas = SKTextureAtlas(named: "Sprites")
let texture = atlas.textureNamed("ball")
let sprite = SKSpriteNode(texture: texture)

you can be less specific and just specify a texture:

let texture = SKTexture(imageNamed: "ball")
let sprite = SKSpriteNode(texture: texture)

If you're looking to use an already created sprite sheet, check out this answer on SO: Using sprite sheets in xcode.
