Converting to Char/String from Ascii Int in Swift

I\'m trying to convert the integer representation of an ascii character back into a string.

If you want only String characters from A... you can use this func:

func characterFromInt(index : Int) -> String {
        let startingValue = Int(("A" as UnicodeScalar).value)
        var characterString = ""
        characterString.append(Character(UnicodeScalar(startingValue + index)))
        return characterString
    }
