Also make sure you're not including an Objective-C file from a .cpp or .c file.

Example: a PhotoManager.mm might include the header file from the Objective-C pair PhotoObject.h/PhotoObject.mm. Then, if MyAwesomeCppFile.cpp includes PhotoManager.h, suddenly PhotoObject.h doesn't know the basic Objective-C classes and keywords.

A solution would be to use #ifdef __OBJC__ if you can get away with it.

Otherwise designate the .cpp file type as Objective-C++ Source in the file's properties panel (Top right window control => "Identity and type")
