Suggested approach: Start with a brief introduction to what
Result does, saying that it’s an enum encapsulating success and failure, both with associated values so you can attach extra information. I would then dive into the “when would you use it” part of the question – talking about asynchronous code is your best bet, particularly in comparison to how things like
URLSession would often pass both a value and an error even when only one should exist at a time.
If you’d like to go into more detail, more benefits of
Result include being able to send the result of a function around as value to be handled at a later date, and also the ability to handle typed errors.
Estimated difficulty: Intermediate
