Expanding a native type code challange

I am not sure what's wrong with my solution, when I type it in playground it works, but when I submit it it says bummer :-(

extension String {

func add(Value: Int) -> Int? {
    if let strToInt = Int(self) {
    return strToInt + Value
}
    else {
        return nil
    }
}

}

types.swift 
// Enter your code below

extension String {

    func add(Value: Int) -> Int? {
        if let strToInt = Int(self) {
        return strToInt + Value
    }
        else {
            return nil
        }
    }
}
