Can you elaborate on why you feel IB and TDD are incompatible? I haven't found it particularly difficult to drive out behavioral tests for views/view controllers powered by NIBs (at least relative to Obj-C TDD in general), since any actions or subview settings you declare in your NIB will be exposed programmatically as well. I'd love to hear about what pain points you have.
