Good luck. Apple absolutely controls how apps are written (not just the tools required but literally how code is written) and distributed. If they don't like what you've worked so hard to create, they won't allow it on their app store, including if it competes with something they come up with (even after the fact). Oh, and even if you've dotted all their arbitrary i's and crossed all their arbitrary t's, they'll take 30% right off the top. No thanks.
