Hello everyone,

I am looking a way to express something similar to the following code in
Swift terms:
protocol AnyViewModelInput {}
protocol AnyViewModel<ViewModelInput>: ViewModelInput where ViewModelInput:
AnyViewModelInput {
    var input: ViewModelInput { get }

Is it possible in current Swift? Will it be possible if generic
manifesto will be implemented in full? Also if you know how to express a
similar idea in any other language, I would love to see examples. How does
such construct is named in other languages?

Thank in advance,
