We do that, but we already had a big xcconfig infrastructure to support configuring our projects. If you let qmake create a Xcode project for you, you can see pretty clearly what's required, and you can move that into a Xcode config file. The tricky part is the way they invoke moc. They write a makefile into the project.xcodeproj package called qt_preprocess.mak, then invoke it using a run script build phase that runs make. I replaced that with a custom build rule:

Process: Source Files with names matching: *.h
using: Custom script

script:
/path/to/moc ${INPUT_FILE_PATH} >${INPUT_FILE_DIR}/moc_${INPUT_FILE_BASE}.cpp

with output files:
$(INPUT_FILE_DIR)/moc_$(INPUT_FILE_BASE).cpp

I only did this with a small project, so YMMV, but we're planning to put together some fairly large projects pretty soon.
