Got error after include Foundation.h file
I am trying to induce Foundation/Foundation.h in my project but i got error of NSString; did you mean QString ......
I saw old question(https://forum.qt.io/topic/12805/objective-c-and-qt) and did like they but still same error.
What does your .pro and your header/source file(s) look like?
My problem was in the pro file.
