Saving revisions of swift

Hi, is there a way to periodically save your project in swift ?. I had a quick look through the menu options, and i can't see anything?

This seems to be a question not about Swift, but about your editor and/or development environment.
Are you using Xcode?

sorry, its xcode

Then you'll probably get better results by asking on the Apple developer forums over at https://developer.apple.com/devforums/
