How to include Cocos2D to an already existing iOS project?

Is there any complete documentations?

I don't find anything also.
I made a "starter" project with swift, but forgot to save it out and now all of my project code is in there.
I'm thinking about to redo all the things because my current solution uses a full-screen window to draw the things, but it will be better to use a custom view instead of a window.

I'm planning to make a separate project, then move my other things in it. Do you want to have a copy of it? I don't really have ETA about it.
