As an example: protocol MyShapeProtocol { func make() -> Shape?} class Circle : Shape {} class CircleMaker : MyShapeProtocol{ func make() -> Circle? { return Circle() }} This will not work.For that to work I’ll need to use toe associatedtype “hack”: protocol MyShapeProtocol { associatedtype ShapeReturnType : Shape func make() -> ShapeReturnType?} class Circle : Shape {} class CircleMaker : MyShapeProtocol{ func make() -> Circle? { return Circle() }} Is there a real value in adding the associatedtype line? -- -- Howard.
