When I started my project I was happy to use Groups in Xcode rather than literal folders: Since I\'m using the browser in Xcode to access everything, stuff was nicely organi
As of Xcode 4.5 when you drag in a folder structure it is automatically turned into nested groups in the Project Navigator. Then, if you look on disk (e.g. right click and choose Show in Finder), the folder structure has been retained.
I found trying to fix things from an older project was just a pain. It turned out much easier to just delete these files and drag them in again.
