Question: How has Swift changed since it was first released in 2014?
Suggested approach: This can either show how long you’ve been writing Swift, or it can show you have an interest in the language’s evolution. Talk about the addition of
defer in Swift 2, the massive Cocoa renaming from Swift 3, the introduction of
Codable in Swift 4, or whatever takes your interest.
- There are over 100 interview questions in the system. Once you've read the question and come up with a suitable answer, try reading my suggested approach below.
- To see another question just refresh the page; a new question is chosen every second.
- 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. The handful that are harder are specifically marked – the majority are suitable for junior to intermediate developers.
- 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 test instead – it has three difficulty levels.
