I'm pretty sure you have to run that everytime you add new files. The
command only generates the initial XCode Project, but it does not
updated it after you add new classes. Also make sure that your .pro file
has the headers for the new class.

HEADERS +=  MainWindow.h
SOURCES += main.cpp MainWindow.cpp
