We have two developers working on the same project. This project is integrated with Git.
When one developer is working on the project and other developer tries to run the project, Xcode 4 crashes as shown.

What could be wrong and how to rectify it?
Thanks!
I think what has happened is that your project.pbxproj file has gone some merge conflict stuff embedded in it. Open it in a text editor and look for lines like:
>>>>>>>
If you see that, it means you need to clean up the file.
There’s no way for git to be doing anything across systems while both developers are just working, so the issue is something someone checked in…
Another issue is that if a project file is changed by another developer, and someone pulls the changes with the project open, they have to re-open the project to see all of the targets as they are meant to be used in the project. I have not seen that cause a crash though.
