At the moment the app doesn't employ the use of the Clang static analyzer but I am looking into using libClang both for live issues as you code and also for auto complete. Also, XIB/Storyboard support is one that will be worked on just as soon as git support is out of the door and in the hands of the users.
You could maybe look into the jailbreak community. It is possible to compile (etc) on the device itself and they previously had an IDE in the works which was never finished. I am sure they'd love to have a look at this.
(I'm the dev by the way)
