iOS Developer Interview Questions
What steps do you take to identify and resolve crashes?
Suggested approach: Walk through your knowledge of debugging from the basics upwards. Do you use breakpoints? Do you use assert() or precondition()? Do you write to a log? Do you download crash logs from iTunes Connect?
All these things help provide data points we can use to find and fix problems in our code, because once you know where the problem is it's usually(!) fairly straightforward to fix.
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.
