So make sure you remove and ignore these directories in source control so that they don't get re-added and cause the problem again.Ī problem which I had: When I added a casetagram library into my project, then a few seconds after launch of Xcode, before indexing of files (as I think), it had become freezes. non-retina or different versions of Xcode could use those files differently and the source-control merging could make them inconsistent. so one cause could be if you use source control across multiple machines that have the same username and those files aren't ignored (which they should be if you're using source control). Those directories store things like window positions, what files are open, which project groups are expanded, etc. Remove the following directories: MyProject.xcodeproj/xcuserdata Update: Here is some additional information from comments that solved the problem.

I can't even figure out how to stop the project from launching on start up. Because the project launches right away I cannot access any of Xcode's features. The first one loads sometimes but the second one always freezes.

I was in the middle of working on two projects so when Xcode starts up it immediately launches the two projects I was working on. I am running Xcode 4.3.3 on the new Macbook Retina and out of the blues Xcode started freezing right after launching.
