iOS Development Techdegree Student 5,275 PointsHelp me fix this error: "Bummer! Make sure you're adding an add method that takes an Int and returns Int?"
No matter what I try, including straight up copy-pasting solutions that others have posted success with, I keep getting the same error: "Bummer! Make sure you're adding an add method that takes an Int and returns Int?"
my code works fine in playground, and returns an Int? wrapped in optional(). I am at my wit's end. Any suggestions are welcome.
// Enter your code below
extension String {
func add(_ value: Int) -> Int? {
guard let originalStringAsInteger = Int(self) else {
return nil
}
return originalStringAsInteger + value)
}
}

externally. In the example provided value
is the parameter name used when calling the method.
If you remove the external name like this:
extension String {
func add(value: Int) -> Int? {
guard let originalStringAsInteger = Int(self) else {
return nil
}
return originalStringAsInteger + value
}
}
Then the code will be accepted.
