In appCode, you can build and run in the simulator with one click. To the best of my knowledge, nobody has figured out how to do that outside of Xcode before. Getting the app installed is easy, but opening the simulator and running the ap not so much.
I'm sure there's a ton of other things like this appCode can do, that so far nobody else has been able to.
Which is why it would be great if these awesome features were exposed wih CLIs.
I'd pay good money to be able to build and archive, and distribute for enterprise, with the CLI.
