34,475 PointsIn an extension to the String type, declare a function named transform. I can't figure it out. What's wrong?
Everything seems to be just fine but there an error: "... declare a function named transform".
// Enter your code below
extension String {
func transform(argument: (String) -> String) -> String {
return argument(self)
}
}
