Qt 5.5 OSX - This application failed to start because it could not find or load the Qt platform plugin "cocoa".

When I build my app in Qt Creator, it runs fine under Debug mode. When I switch to Release mode, clean, run qmake, and rebuild... I get the following error when running the Release version:

This application failed to start because it could not find or load the Qt platform plugin "cocoa".

Any ideas??

I found that if I run macdeployqt after I build it, I get that error. I have to delete the whole build directory content before running it again and it's fine after.
