iOS Developer Interview Questions
Can you explain MVC, and how it's used on Apple's platforms?
Suggested approach: MVC is an approach that advocates separating data (model) from presentation (view), with the two parts being managed by separate logic (a controller). In theory this separation should be as clear as possible, but for bonus points you should talk about how view controllers sometimes get bloated as code gets merged together into one big blob.
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.
