Swift - get reference to a function with same name but different parameters

Question

I\'m trying to get a reference to a function like so :

class Toto {
    func toto() { println(\"f1\") }
    func toto(aString: String) { println(\"f2\") }
}
         


        

Answer 1

Since Toto has two methods with the same name but different signatures, you have to specify which one you want:

let f1 = aToto.toto as () -> Void
let f2 = aToto.toto as (String) -> Void

f1()         // Output: f1
f2("foo")    // Output: f2

Alternatively (as @Antonio correctly noted):

let f1: () -> Void     = aToto.toto
let f2: String -> Void = aToto.toto

If you need the curried functions taking an instance of the class as the first argument then you can proceed in the same way, only the signature is different (compare @Antonios comment to your question):

let cf1: Toto -> () -> Void       = aToto.dynamicType.toto
let cf2: Toto -> (String) -> Void = aToto.dynamicType.toto

cf1(aToto)()         // Output: f1
cf2(aToto)("bar")    // Output: f2
