iOS Developer Interview Questions

When would you choose to use a collection view rather than a table view?

Suggested approach: Collection views are there to display grids, but also handle entirely custom layouts, whereas table views are simple linear lists with headers and footers.

For bonus points, you could discuss the UICollectionView lists introduced in iOS 14, because they really blur the lines between the two types.

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.
