Hi, I wonder what's the correct way to express something like this in swift:
Say I have a superclass with two subclasses:
class Animal {}
class Dog: Animal {
let name = "Dog"
}
class Cat: Animal {
var name: String {
return "Cat"
}
}
And I want to display the name with a switch:
switch animal {
case let a as Dog, let a as Cat:
label.text = a.name
default:
break
}
Swift currently won't allow me to use multiple value-binding patterns like
this. I wonder what's the right way to express it? Must I repeat the statements?
switch animal {
case let a as Dog:
label.text = a.name
case let a as Cat:
label.text = a.name
default:
break
}
I also tried fallthrough, but swift won't let me fall through to a
value-binding pattern:
switch animal {
case let a as Dog:
fallthrough // error
case let a as Cat:
label.text = a.name
default:
break
}
I'm at my wits end. Could someone shed some light on this? Thanks.
