It is easy... select the XIB file and make sure the desired target of the project is checked under the "Target Membership" section (under the "Show the file inspector" tab), and your problem is solved.

It is usually happening when you made a copy of an exists file and added to the project manually because in that case you should check the above mentioned target manually as well.
