the compiler is asking me something have already done
// Enter your code below
extension String {
func transform(aString: (String) -> String) -> String {
return self
}
}

17,232 PointsCan you post your updated code? Because I just passed the challenge with this code, your code, with an omitted external name and the return I mentioned in my answer.
extension String {
func transform(_ aString: (String) -> String) -> String {
return aString(self)
}
}
