When I click on check work it gives me this message "Bummer! You need to override the implementation for the fullName() method to pass the challenge", but I'm pretty sure I've done so.
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 "\(firstName) \(lastName)"
}
}
let someDoctor = Doctor(firstName: "Dr.", lastName: "Smith")
someDoctor.fullName()

An overidden function needs to do something different to the function in the superclass. Yours doesn't at the moment.
You need to change the returned value from "Sam Smith" to "Dr. Smith" - that makes it different.
Try something like:
class Doctor : Person{
override func fullName() -> String {
return "Dr. \(lastName)"
}
}
let someDoctor = Doctor(firstName: "Steve", lastName: "Hunter")
You don't need the init method, either, as it is doing nothing different to the superclass version.
Steve.

23,970 PointsYou need to override the function with the correct return that the challenge is asking for:
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: "Jeff", lastName: "McDivitt")
someDoctor.fullName()
