Apple IOS Engineer interview questions

One of the best interviews I've ever had. We were both pretty confident I did not have the experience required to have this job within the first 15 minutes. He kept interviewing me anyways, letting me know where I went wrong, and giving me great feedback. He also gave positive reinforcement and said that it is possible for someone in my position to obtain this kind of position in the next year or so. Best technical interview I've ever had.
