Try closing Xcode and then reopening and doing a clean build.

If that doesn't fix it, it's possible you've got a circular reference in one of your header files.

This can happen when foo.h #imports "bar.h" and bar.h #imports "foo.h" (or sometimes its a chain of three or more header files importing each other in a circle) and it leads to spurious errors like the one you're seeing.

The solution is to try to avoid importing headers in your .h files, and instead use @class references for external classes in the .h files and put the #imports in the .m files instead.
