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!
