Use Type Erasure return Generic Type in a function with Swift (Cannot convert return expression of type…)

Question

I have a problem with generics in swift. Let\'s expose my code.

protocol FooProtocol {
    associatedtype T
}

protocol Fooable { }
extension Int : Fooable { }
         


        

Answer 1

Is the following what you tried to achieve? (compiled & tested with Xcode 11.4)

func createOne() -> some FooProtocol {
    let anyFoo = AnyFoo(p: FooImpClass())
    return anyFoo
}
