Tool for comparing Xcode project files

Question

I've been given the Xcode project files for version 1 and 2 of a iOS app. Version 1 is working, version 2 is buggy with more features. The original programmer is no longer available. No versioning system was used.

Is there a tool to compare the different projects - so I can see what code was added between version 1 & 2?
