I'm writing an extension to String to return a reversed version of it:
extension String{
func rev()->String{
var r = ""
r.extend(reverse(self))
return r
}
}
The code works fine, but I'd like to call this method reverse, and not rev. If I do it, I get an error as the method name conflicts with the generic function reverse:
extension String{
func reverse()->String{
var r = ""
r.extend(reverse(self)) // this is where I get the error
return r
}
}
Is there a way to specify that I mean the generic function reverse inside the body of the method?
You can always call the Swift function explicitly by prepending the module name, e.g. Swift.reverse():
extension String{
func reverse()->String{
var r = ""
r.extend(Swift.reverse(self))
return r
}
}
Note that you can simplify the function slightly to
func reverse()->String{
return String(Swift.reverse(self))
}
This works because Swift.reverse() returns an array, Array conforms to
SequenceType, and String has a constructor
init<S : SequenceType where Character == Character>(_ characters: S)
