iOS Developer Interview Questions

How would you explain Dynamic Type to a new iOS developer?

Suggested approach: This is a sneaky question, because if you say “I don’t use it” or (worse) “I don’t know what it is”, it sort of means you don’t pay attention to accessibility or user preferences. Dynamic Type is a way of allowing the user to adjust their preferred size for all fonts in all apps, and it's surprisingly easy to use from both a developer and user perspective. SwiftUI even defaults to using it across the board!

  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.
