First of all, thank you for taking the time putting this together.

Next, this should be used as a good example of "types of questions not to ask in a technical interview".

These will give little insight into what a candidate actually knows other than random trivia. I've seen a lot of junior interviewers focus on these types of questions, to perilous results.

I actually think high level questions like these are just conversation starters which can get into highly technical conversations quickly.

Sort of like the technologies themselves; GameCenter and CoreEverything are abstractions of lower level functionality. Being able to discuss their purpose, how to use them, and how to glue them together is what a good developer is. The rest is just syntax.

Moreover, I never see these questions as just being a one-by-one trivia list for applicants. More of just a thing to look over, see the technologies that your app may use, and then use these questions as kinda a way to launch discussion with an applicant to see how well the know their stuff.
