Re: [swift-evolution] [Proposal] Allow enumerating cases in enumerations

Maybe a way we could opt in is by only doing this for enums with out turples? i.e enum ABTestingBrah { case A case B } I'm not sure if enums that take turples would need this functionality. *___* *James⎥Head of Trolls* *ja...@supmenow.com

And it is something the compiler can check whether it is necessary for your code or not based on some simple and easy pattern. If it is so simple, why not let the compiler handle it? On 4 July 2016 at 16:02, Vladimir.S via swift-evolution wrote: > On 04.07.2016 21:21,

Re: [swift-evolution] [Proposal] Allow enumerating cases in enumerations

My issue with this being opt-in is third-party libraries. The developer of a library may not have intended or thought of a use for the enum this way but some other developer might have. Being opt-in would prevent such scenarios from easily happening or require the developer to (again) manually

That is actually something I argued over this list with other users and (at least when I proposed) was not very well accepted. This certainly has my +1. On 4 July 2016 at 02:52, Gabriel Lanata via swift-evolution wrote: > I know! I am amazed this hasn’t had a formal

Re: [swift-evolution] [Proposal] Allow enumerating cases in enumerations

I know! I am amazed this hasn’t had a formal proposal and review yet. I did a search through the mailing list and found that it has been mentioned many times before (these mentions are linked in the proposal) but it has never gone into review. The other posts proposed slightly different

Re: [swift-evolution] [Proposal] Allow enumerating cases in enumerations

Hi there, right now, I have 7115 unread messages in my Swift-folder, so I'm surprised that there hasn't already been a successful proposal to add this feature… afaiks, it wouldn't hurt anybody, and many people want to have it. Therefore: +1, and good luck! ;-)

Re: [swift-evolution] [Proposal] Allow enumerating cases in enumerations

+1. The only thing that I don't like is that it may lead to confusion to novice developers because it only work with "basic" enums i.e. enums without associated values. The same thing happens with protocols with associated types, where you can't use the protocol with associated types as the type

Re: [swift-evolution] [Proposal] Allow enumerating cases in enumerations

+1 since it makes it easy to get the number of possible enum values, but I thought I'd tell you: there's no "Wind" type in Pokémon. It's "Flying". On Sun, Jul 3, 2016 at 18:36 Gabriel Lanata via swift-evolution < swift-evolution@swift.org> wrote: > Hello, this has been proposed multiple times

Hello, this has been proposed multiple times before in different ways. Link to detailed proposal draft: https://github.com/gabriellanata/swift-evolution/blob/master/proposals/-allow-enumerating-cases-in-enumerations.md It is currently not possible to enumerate through all the possible cases
