Supposedly in a protocol, “Self” is the class implementing the

have a return type of Self so they can return self, and thus have
the extension method behave the same as it would as if it were
defined in the class adopting the protocol.
I am not sure if this solves your particular problem, but in general
you must do this
protocol MyProtocol
{
typealias Element
}
extension MyProtocol where Element == Self
{
// use Element instead of Self
}
At least I have found this to work better in my use cases.
