I am new to here, please forgive me if this question has been asked before (I did not find the similar thread when searching the Forum).

Basically, I already have some fairly large and complex Xcode projects, and I want to re-write the User Interface of the application using Qt. I already know that I can create a xcodeproj file using "qmake -spec macx-xcode myproject.pro" for my Qt UI project. But this will require me to merge my existing xcodeproj into this new one. Since my existing Xcode project is fairly large and my Qt UI part is very small, I prefer to integrate the Qt C++ code into my existing xcodeproj. Is there an easy way to do this?
