What am I missing? The code I've written works correctly in Swift Playgrounds but the coding challenge won't accept my answer.
// Enter your code below
extension String {
func addToString(intToAdd: Int)-> Int? {
guard let stringInt = Int(self) else {
return nil
}
return stringInt + intToAdd
}
}

20,185 PointsHey Stephen Zabrecky, the challenge editor is very specific about names, arguments etc. So the function has to say add not addToString
extension String {
func add(value: Int) -> Int? {
guard let stringValue = Int(self) else {
return nil
}
return stringValue + value
}
}
