The review of "SE 0192 - Non-Exhaustive Enums” had extensive discussion and has been returned for revision.
The proposal author, Jordan Rose, is working on a revised proposal that includes:
- Alterations to the naming of the attributes.
- New affordances for how switch statements work with non-exhaustive enums.
There will be a second round of review, but there is active discussion considering the latter point right now on swift-evolution on the thread "Handling unknown cases in enums”:
[swift-evolution] Handling unknown cases in enums [RE: SE-0192]
I encourage anyway interested in that topic to follow/participate in that thread.
