Hi, has anyone resolved this code challenge? Help appreciated

Not sure how to override

class Person {
    let firstName: String
    let lastName: String

    init(firstName: String, lastName: String) {
        self.firstName = firstName
        self.lastName = lastName

    func getFullName() -> String {
        return "\(firstName) \(lastName)"

// Enter your code below

Hi Geovanny,

You need to create a subclass "Doctor" that inherits from the Person class. Then in the Doctor class you will create an override function for "getFullName()" that returns the proper string.

class Doctor: Person {
    override func getFullName() -> String {
        return "Dr. \(lastName)"
let someDoctor = Doctor(firstName: "Sam", lastName: "Smith")
