I’ve been reading up a bit more on Xcode 4. The prior version, Xcode 3, had SCM integration with Subversion, Perforce, and CVS. The new version has support for Subversion and Git. (I’m not sure if they dropped CVS and Perforce, but I’ve only seen Subversion and Git mentioned.) And, of course, I decided a couple of weeks ago to use Mercurial instead of Git. Oh well. It’s not a big deal to do version control outside of the IDE, but it’s always nice to have it integrated.
