Hi Alistair,
I'm afraid that you will have to debug this problem by yourself, I
don't really know what's happening here...
The function where the logic resides is rb_require_framework() inside
objc.m. Maybe you can add some debugging statements there.
As for your Xcode problems, without a complete stack trace from the
debugger it's also hard to know what's happening. Also, what are you
trying to build / run exactly?
