Is there a way to compare the code in the old Xcode project with the new Xcode project?

Question

I have a developer who worked on an old Xcode project for me. Is there an easy way to compare the files in his new Xcode project with what was in the new Xcode project to quickly see what changes he made and how the old code changed? It drags on, and finally I turned his hand to send me a new Xcode project. He claims that the old code was garbage, including the old encoder, so I would like to see if he really made any changes to the old guy’s design or simply, “talking”.

Answer 1

Of course, use the diff command (from the terminal window).

" " " ", , - :

diff -r old-project new-project

"-r" .

. , - (, svn). , , , .

Answer 2

FileMerge. "///FileMerge"
