iOS Developer Interview Questions
How familiar are you with XCTest? Have you ever created UI tests?
Suggested approach: Be prepared to talk about the challenges you’ve faced when designing tests, particularly when it comes to user interface tests. It’s a good idea to make sure you’re crystal clear on the differences between unit tests and integration tests. Tip: I’ve never met a development team that was 100% happy with their iOS UI tests.
Estimated difficulty: Easy

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.
