Not sure if this is coincident with updating to Xcode 5 and command line tools but I was unable to do a SVN update on my project as I got an error about the working copy being out of date or expiring. I have never seen anything like this and couldn't figure out how to get around it so I had to delete everything on disk and pull a new copy from SVN. Thankfully I didn't have edits locally.
What is the cause and fix for this? I also sure hope XS updates start rolling out. I feel this iOS designer is really holding up the show on XS and getting us fixes and improvements.
