I am trying to construct an object that conforms to a protocol `A` and also sublclasses object `B`. Protocol `A` requires an initializer that will be used to construct it. Xcode will attempt to autocomplete the initializer but then ultimately gives the following error:
`error: argument passed to call that takes no arguments` Here is some sample code: ``` protocol MyProtocol { init(foo: Int, bar: String) } class MyOperation: Operation, MyProtocol { required init(foo: Int, bar: String) { super.init() } } func makeMyProto<T: MyProtocol>() -> T where T: Operation { return T(foo: 0, bar: "bar") } ``` It’s worth noting that this only fails when subclassing `Operation`. Subclassing `NSObject` or several other objects seems to work. Hopefully there is a way to do this. Ultimately, I just want this generic method to construct a thing that is both an `Operation` and conforms to a protocol. Any help here would be greatly appreciated. Thanks! -Bradley _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
