animation can be hundred of files. atlas puts them in one large file.

reading one file (large with lots of images) is much more efficient then reading hundreds of files (with one image each)

rendering of one large image and then showing only part of it is much more efficient then rendering each file separately.

Directly from the SKTextureAtlas class reference :

Texture atlases can improve memory usage and rendering performance. For example, if you have a scene with sprites drawn with different textures, Sprite Kit performs one drawing pass for each texture. However, if all of the textures were loaded from the same texture atlas, then Sprite Kit can render the sprites in a single drawing pass—and use less memory to do so. Whenever you have textures that are always used together, you should store them in an atlas.
