Please Help me. Don't know why I still get an error.

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 func getFullName() -> String { return "Dr. (lastName)" } }

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

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 func getFullName() -> String {
        return "Dr. \(lastName)"
    }
}

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

Hi Cruiz,

One issue I can see is in your Doctor class you are attempting to override a method that doesn't exist in the parent class. The method in the Doctor class should have the same name and signature as the parent class method. E.g.

override func fullName() -> String {
 return "Dr. \(lastName)"
}

Hope that makes sense

Ian
