I work in a large IT department, but there are only 2 people who are Xcode programmers. My boss hasn't started programming in Xcode yet, but wants to. We have a Mac Mini that we want to use to keep our source code. Wondering if we should go ahead and set up Mac OS X Server and use Xcode Server, or just put our git repository on the Mac Mini and use it as a file server. Is Xcode Server worth the trouble of setting up Mac OS X Server?
