Well, I've been using XCode 1.5 for a few days now. Yesterday, Interface Builder crashed while saving one of my NIB files. Next time I tried to open that NIB file IB crashed again, and the NIB file had vanished from my disk when I looked for it in the Finder.
So I tried to use the "~" backup version. IB crashes every time I try to open the backup version as well!
Thanks XCode 1.5! Now I've got a lot of work to do to rebuild that file from a backup 2 days before.
Just thought I'd warn you all, and was wondering if anyone else has had similar experiences.
