iOS Object-Oriented Swift Class Inheritance Overriding Methods

What am I doing wrong? (Doublecheck implementation of overriden method)

How should I implement the method?

objects.swift
class Person {
  let firstName: String
  let lastName: String 

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

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

// Enter your code below
class Doctor: Person {
override init(firstName: String, lastName: String) {
  super.init(firstName: firstName, lastName: lastName)
}
override func fullName() -> String {
 return "Dr. \(firstName)"
}
}

let someDoctor = Doctor(firstName: "Sam", lastName: "Smith")

Well according to the question it has to be the last name. So a minor tweak is needed in your return statement in the fullName function. Here instead of firstName it should be lastName
