iOS Developer Interview Questions

What is the purpose of GameplayKit?

Suggested approach: The clue is in the name: GameplayKit contains lots of helpful classes for games, such as AI strategists, state machines, and pathfinding. However, there’s no reason its components must be limited just to games, because you can use them just as well in apps.

  Estimated difficulty: Intermediate

Important notes

  • There are over 150 interview questions in the system. Once you've read the question and come up with a suitable answer, try reading my suggested approach and see if it helps you add more detail.
  • These questions are not designed to be hard; a good interviewer is more interested in generating discussion that lets your ability and interests shine through.
  • If you answer a question with "yes" or "no" you've missed the point – interviewers prefer you to provide reasoning, explanation, or detail, so try to elaborate with examples!
  • If you're looking for detailed technical questions about the language, you should try my Swift tests instead – there are multiple challenges that will work your brain hard.
  • For a whole series of coding challenges, I wrote the perfect book for you: Swift Coding Challenges.
