When I tried calling a specific superclass implementation, there was a stack
overflow due to the infinite recursion.
class Once {
func value() -> Int {
return 1
}
}
class Twice: Once {
override func value() -> Int {
return 2
}
}
class Thrice: Twice {
override func value() -> Int {
return 3
// EXC_BAD_ACCESS:
// return Once.value(self)()
}
}
let once = Once()
once.value() //-> 1
Once.value(once)() //-> 1
let twice = Twice()
twice.value() //-> 2
Once.value(twice)() //-> 2
Twice.value(twice)() //-> 2
let thrice = Thrice()
thrice.value() //-> 3
Once.value(thrice)() //-> 3
Twice.value(thrice)() //-> 3
Thrice.value(thrice)() //-> 3
