CameronBanga, appreciate you sharing this! As a long-time iOS designer and developer, I appreciate you helping and effort in finding a great one.

I unfortunately think that all of your questions are at best, filtering questions to ensure they have base familiarity with pretty benign facts and at worse, questions that give no insight at all into iOS abilities. Your design questions are, in particular, extremely trivial and almost silly.

Feel free to reach-out to me if you'd like to collab on a better list.

Everyone else reading this, no even semi-serious iOS developer or designer would endorse these questions as a robust way to filter candidates or even teach yourself.
