But if you need to do something slightly unusual, like calling a shell script to generate resources, it's horrible.
Not quite true. Xcode provides a "Run Script" build phase that lets you enter your shell script right into the IDE. A lot of handy environment variables are also there. You can easily reach your project via $SRCROOT, or modify the resources of the output bundle via "${CONFIGURATION_BUILD_DIR}/${PRODUCT_NAME}".
That's the sort of stuff I mean when I say "horrible". :)
It'll just run the script every time, rather than doing anything smart with dependencies. Output from the script might or might not be picked up and tracked properly by the IDE. If you accidentally mess something up nothing will detect or prevent that.
(Edit: should add that I haven't given it a proper try in recent Xcode versions. I probably should.)
