[swift-evolution] [Review] SE-0194: Derived Collection of Enum Cases

[swift at lng.la]

> • What is your evaluation of the proposal?

+1, very happy to see this coming together! I've been interested in this feature since the early days of Swift.

My only reservation is that I would have expected to be able to access the list of values without any extra annotations. Is there a reason to not automatically give ValueEnumerable conformance to any enum that fits the criteria for synthesis?

Definitely, for the reasons mentioned in the proposal's motivation.

> • Does this proposal fit well with the feel and direction of Swift?
>
Yes, this feels like a very natural addition to the language.

>
> • If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?
>
I've used the GetValues API in C#, and though I think the proposed API is a much better fit for Swift, I did appreciate that GetValues could be used on any enum without needing to opt in manually.

Full reading.
