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 fullName() -> String {
return "Dr. \(lastName)"
}
}
let someDoctor = Doctor(firstName: "FirstName", lastName: "LastName")

Front End Web Development Techdegree Graduate 33,271 Pointsit wants you to override fullName to pass. you don't need to override the init, the Doctor class inherits from Person so it inherits the init. in Doctor, override the fullName from Person and change the body to return what the challenge asks for, then create a Doctor instance with the name Sam Smith. the first name will not be Dr. Dr. is what your overridden fullName function will return along with the last name.
