Having the same issue as this guy it seems:
Xcode restoring snapshot does nothing
I've been creating snapshots before I try certain things and have never had to restore one.
I tried a couple of days ago and xCode presents me with the differences between the code, great.
I click restore and it says it's completed the task, however the code is the same as it was before! I now click to restore again and xCode says there is no code difference! Very frustrating and worrying if I do require a restoration!
Help!
I'm using xCode 4.6
