I have a foder structure something like:
- MyProj
|- Unity-iPhone.xcode
|- All my unrelated but very important source folders and files.
|- Unity Project
|- Assets
|- Scripts
|-etc
So when I build an iOS build within Unity it has been building into MyProj, appending the xcode data.
This has been working great until I upgraded to 3.1.0f3. Now when I build it deletes the entire MyProj folder first and then tries to build. Obviously this fails completely because it just deleted itself and a bunch of unrelated but very important code.
So I just lost the whole days work
