The first major hurdle I encountered in trying to learn XCode is that since there was a new update very recently…almost ALL of the tutorials out there are based on the common use of XIB (pronounced ‘zib’) files and NIB files…while the new version of XCode is designed around the use of the new Storyboard feature.

This site is the only one I’ve found so far with a solid starting point with the new features of XCode.  Enjoy.
