iOS Developer Interview Questions

What experience do you have working on macOS, tvOS, and watchOS?

Suggested approach: Keep in mind that many company have significant investments in Apple computers – being able to make macOS apps for internal use can be a real boost. I would also suggest that saying you've dabbled in something like watchOS demonstrates curiosity and an ability innovate. If you’ve moved apps to the Mac using something like Catalyst that’s also worth discussing here, particularly if you’re able to compare it to SwiftUI.

  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.
