Not entirely true. Appcode, an alternative IDE, also works fine with development on devices and the simulator. I haven't heard of an open source plugin to do this yet, though. So no way to do that for vim. (There's a vim plugin for app code though, it's not perfect but ok).

Ah; I tried Appcode and hated it too much to get to debugging, but it is nice that someone's figured out how to interoperate.
