Newtype for Swift

[timv (Tim Vermeulen)]

We already have a way to do that:

struct MyType { var x: Int }

If that’s all you want, then you already have it.

Not really, this still lacks an easy way to do protocol forwarding to the inner value. Something like

newtype Foo: Equatable, Hashable = Int

would remove a lot of the friction.
