iOS Developer Interview Questions

How much experience do you have using iBeacons? Can you give examples?

Suggested approach: iBeacons were introduced way back in iOS 7, and have found mixed use – unless you’re applying for an iBeacon development job this is one you can probably skip with “I haven’t used them much, but I’m keen to learn!”

Of course, if you do have experience then this is your time to shine: talk about major and minor identifiers, talk about positioning beacons overhead to avoid interference from people and devices, talk about ranging, and more.

  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.
