I essentially did this for my senior capstone at university, and it worked pretty well for my purposes. Granted, I was working mainly in data visualizations. I'd propose that doing so is actually not too bad of a thing if you're a) not rapidly prototyping, and b) need to manipulate the large majority of the UI in code anyways. I haven't made many more iOS apps after that, so I can't really say that with lots of experience, but still. As long as you're mindful of how you structure your code, it's not extremely difficult to maintain.
