iOS Developer Interview Questions
What are the benefits of using child view controllers?
Suggested approach: We all know that view controllers can grow to hideous proportions, so I think the best approach here is to acknowledge that and present child view controllers as one solution – they provide the ability to carve off parts of your UI into smaller chunks, retaining all the same functionality but making your code smaller and simpler. It’s also worth mentioning how child view controllers can also make our code more reusable, because the child can be used in other parent view controllers.
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.
