Most likely, you decided to delete some of the frameworks that you do not need, and you deleted them, but chose "Move to Trash" instead of "Delete Link".
The problem is that this structure was not included in your project folder. It is located in the system folder when it can be used by several projects. Thus, you not only could not compile the current project, but also all the projects on your computer.
If you have any frames, you can right-click them and select the "Show in Finder" check box. Than you can find your deleted frameworks in the recycle bin (if they have not been erased yet) and put them back in the System Framework folder.
If you cannot find this folder, for me it was here: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/System/Library
Of course, when you go to the Applications folder and select Xcode, you must right-click it and click Show Package Contents.
If you removed your frameworks even from the trash, I think you could reinstall Xcode ...
