NEW: Master Swift design patterns with my latest book! >>

Question: How would you compare two tuples to ensure their values are identical?

Suggested approach: This is automatic ever since Swift 2.2 – you can just use == to compare tuples. For bonus points you could mention that tuple comparison does not guarantee that both tuples use the same element names.

Important notes:

  • 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.
  • For a whole series of coding challenges, I wrote the perfect book for you: Swift Coding Challenges.
