Today I experienced a very strange behavior with my XCode (using Version 4.2, iOS 5.0).
I read some another questions, but my problem is diferent and I never before had this issue.
So, XCode gives me the error “The application bundle does not contain a valid identifier.” when I’m trying to run my app on a device (in the simulator just simply does nothing).
I’m sure that the project is correctly set, the bundle ID is correct, my certified is also correct..
I already try a lot of different approaches to solution the problem. Then I realized that it just gives the error when I add a folder to the project with the options “Create folder References for any folder added” selected (like the picture).

I have another apps with folders with folder references, and don’t get any error..
Resuming: If I add the folder I get the error, If I don’t add a folder, the app runs without any problem..
Could someone help me here trying to figure out whats happens (it’s driving me mad).
Thanks!
EDIT:
I managed to mend the problem. I was adding a folder called “Resources”, changing the folder name stops giving me the error.
But I would like to know/understand why was I getting the error..
