Enums vs Structs with static types as containers of values

[mokagio]

The typical use case is the keys of a JSON dictionary.

I prefer enum because you can easily use it in switch if necessary.

But what I don't like I need to repeat .rawValue when using it e.g.:
let userName = json[JSONKeys.userName.rawValue]

I have same opinion as martin. enum. But either way, is not a big deal.
