Re: [swift-users] Using 'SomeProtocol' as a concrete type conforming to protocol 'SomeProtocol' is not supported

[Rien via swift-users]

I think you made your type (enum) unnecessary complex, the following works:

protocol Element {
    
}

enum ElementNode {
    case element(Element)
    case empty
}

var childElements = [ElementNode]()
