Hi,
I have such code compiled and working on XCode 10
```
public struct server: Hashable, Codable
```
{
var country: String
var country\_code: String
var ctrl\_grp: [control\_group]
}
but when try to compile on windows 7 (VS 2017, Winform application - lang Swift), it fails with this "Unknown type “Codable” !
What I have to Do ???

It’s on the list, but to do it in a way that supports all five languages _and_ all platforms takes some additional planning, so I’m afraid this is not supported _yet_.

With what version of Swift is Silver compatible?

You can see the exact overview of what features are implemented at [https://docs.elementscompiler.com/Silver/SwiftEvolution/](https://docs.elementscompiler.com/Silver/SwiftEvolution/). In general, we’re pretty much caught up with 5.2 on core features, and usually stay in sync/ahead with new versions as the progress, but some of the more corner case or more major-undertaking features are still on the list. Codable is one of those, because essentially we need/way to revise a way to make it usable for all Elements languages _and_ all platforms.
I think I’ll bump priority on this though, as I agree it’s a nice to hav feature.

Swift 5.3 is coming soon. And this interesting article quoted RemObjects Swift as “compatibility not perfect”, referencing this thread.
