But that's the issue, you still have to write code to have a basic functionally. I don't remember not being able to do this out-of-the-box in any language I worked with.<br><br>L</div></div><div dir="ltr"><hr><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">From: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:pgwsmith@gmail.com">Patrick Smith</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Sent: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">02/06/2016 02:07 AM</span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">To: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:brent@architechies.com">Brent Royal-Gordon</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Cc: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:me@lmpessoa.com">Leonardo Pessoa</a>; <a href="mailto:swift-evolution@swift.org">swift-evolution</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Subject: </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">Re: [swift-evolution] Working with enums by name</span><br><br></div>Great points Brent. I think the ValuesEnumerable method would be the most straight forward. Also, the number of cases are likely only going to be in range of 6–20, so iterating would be fine I think. People can create something like `Dictionary(Planet.allValues.enumerated().lazy.map{ ($1, $0) })` (I think that’s right) if they really need.<br><br><br>> On 2 Jun 2016, at 2:40 PM, Brent Royal-Gordon via swift-evolution <swift-evolution@swift.org> wrote:<br>> <br>> Or the `ValuesEnumerable` proposal would give you a convenient, though slightly slow, way to do two-way lookup by order:<br>> <br>> enum Planet: String, ValuesEnumerable {<br>> var order: Int {<br>> return Planet.allValues.index(of: self)!<br>> }<br>> init(order: Int) {<br>> self = Planet.allValues[order]<br>> }<br>> case mercury, venus, …<br>> }<br><br></body></html>
