title: Is there a way I can compare code in an old Xcode project with a new Xcode project?
body: <p>I have a developer who has been working on an old Xcode project for me.  Is there a simple way I can compare files in his new Xcode project to the ones in the new Xcode project to quickly see which changes he's done and how the old code has changed? He's be procrastinating and finally i have twisted his arm to send me the new Xcode project.  He claims that the old code was rubbish, including the old coder too, so I'd like to see if he's actually done any changes to the old guy's project or is just plain and simple, 'a talker'.</p>
