iOS Developer Interview Questions
What is the purpose of UIActivityViewController?
Suggested approach: This UIKit class has only one function: sharing your app’s content using whatever other apps the user has. This might mean printing, posting to social media, saving an image to your photo library, and so on.
For bonus points, talk about how you can inject your own activities into the mix, so they appear alongside system-wide services.
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.
