Using delegates on generic protocol

Question

I have got this code:

protocol GenericProtocol: class {
    associatedtype type
    func funca(component: type)
}

class MyType {

    weak var delegate         


        

Answer 1

This is not possible to use generic protocols. Use concrete type or usual protocol instead. You have to declare concrete T outside of those abstractions

For instance, this should work:

class MyType {

    weak var delegate: UsingGenericProtocol? // First error

    var t: T

    init(t: T) {
        self.t = t
    }

    func finished() {
        delegate?.funca(component: t) // Second error
    }

}
class UsingGenericProtocol: GenericProtocol {
    let myType: MyType
    typealias type = T

    init(t: T) {
        myType = MyType(t: t)
    }

    func funca(component: T) {

    }
}

let instance = UsingGenericProtocol(t: 0)
