I just got a new iMac, and installed Xcode 6.3.2 on it. I checked out a copy of my source code repository, and everything runs and builds just fine, but there's one very weird glitch.
When I start up Xcode, everything's normal, I can see which files have been modified, and look at their deltas in the Version Editor.
However, after a couple of minutes (at most), Xcode will suddenly "forget" the source code repository, and mark all my files with ? (indicating that it thinks the file is unversioned).
In the File Inspector, the files now have Version "Not yet committed" and Status "Unversioned", but they also have a Location corresponding to the repository location (e.g. svn+ssh://repo.flim.com/../trunk/Foo/bar.swift since I happen to be using subversion for this project).
From the shell, access to the repository is completely normal - no errors. And if I restart Xcode, everthing works fine - until whatever it is updates, and marks everything as unversioned again.
I've been using this configuration for ages without ever seeing anything like this. I even had to migrate my whole setup to another machine - a similar iMac running the same version of everything - just before getting this new one, with no issues like this at all.
Has anyone seen anything like this before? Or any clues on how to debug it? I have so far had no luck at all finding where Xcode records any log information about source code repository access/errors.
