From Mohamed to Mohamed, i own my iOS app and i can help you with anything iOS. i teach iOS and Swift to non-programmers and CS graduates. I'm not in the U.S. but if you ever need anything hit me up on Twitter @moubarak
i reserved my slot and scheduled a phone call, then they sent me an email that i lost the slot till further notice because they got busy. that's worse than the bad hiring practices that companies already have.
