XCode doesn't understand .pro files, it works on it's own project files
(I think .xcode?).  So when you make changes to the .pro file, those
changes do not have any effect on XCode's build.  You need to re-run the
qmake command that creates an XCode project from a Qt .pro file.

That being said, you should really look into using Qt Creator for doing
Qt development.  It naturally understands .pro files, and works on all
platforms!
