iOS Developer Interview Questions
What is the purpose of the ButtonStyle protocol?
Suggested approach: SwiftUI provides several built-in button styles depending on which platform you're targetting, and the ButtonStyle protocol allows us to create new button styles that can be reused across our apps to get consistent designs.
For bonus points, compare and contrast ButtonStyle with PrimitiveButtonStyle.
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.
