[swift-evolution] Specify type of a delegate which conforms to a protocol

[Alex Hoppen]

At the moment you can achieve the same effect using the following construction (at least that’s what I used):

protocol UIViewControllerProtocol {} // Make sure only UIViewController conforms to this protocol

extension UIViewController: UIViewControllerProtocol {}

protocol MyProtocol {}

let myVar: protocol<UIViewControllerProtocol, MyProtocol>

It’s obviously far longer and less obvious but I hope it at least solves your issue for now.
