I am frustrated right now. I went to revert my project to something else. Unfortunately, for some reason, Xcode's most recent snapshots are just copies of another snapshot that was taken a few days ago. I've changed the code since then. I decided I'd restore anyway. Bottom line: Xcode's snapshot feature SUCKS. I never thought I'd think so, because it worked just fine on another project. I think I'll file a bug report with Apple.
