xcode 4 crash with xib files

[a.terenzi]

I'm porting our app from Xcode 3 to Xcode 4, but as soon as I open any of the .xib files provided with the latest version of Artoolkit for iOS, Xcode 4 crashes, everything is fine with Xcode 3.

Any suggestion? Thanks.

I guess that the problem could be in the project settings because if I just try to add a new empty .xib file to the ARToolkit's project in XCode 4 I get the crash.
Anyone experiencing the same issue?

I'm using XCode 4.3.3 on Lion 10.7.4. Latest ARToolkit version as well.

FYI I managed to avoid XCode 4 crashes by removing every image (png) and every .xib from every example's Resource group folder and finally by adding them again to their original group.

I compared the XCode's project file before and after performing this trick and they looks different because of some IDs. I cannot figure out what this means, but maybe the ARToolkit project can be updated as described above and re-zipped for distribution.

Hope this will help others as well.
