iOS Developer Interview Questions
How are XIBs different from storyboards?
Suggested approach: Once you’ve described how storyboards contain many screens at once, don’t be afraid to wade into the debate: which do you prefer? Let them know you’ve thought about it, even if you end up with saying you’re glad SwiftUI doesn’t use them.
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.
