iOS Developer Interview Questions
How much experience do you have using Face ID or Touch ID? Can you give examples?
Suggested approach: If you’re applying for a job at any company that has secure user data, biometric authentication is almost certainly involved somewhere. Fortunately, it’s not hard to learn!
For bonus points mention the need for a password backup in case Face ID/Touch ID fails, but if you're generally stuck here a good approach might be just to say "I haven't used it before, but I have used the keychain for secure storage."
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.
