Does not pass, not sure why.
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)"
}
}
class Doctor: Person {
override init(firstName: String, lastName: String) {
super.init(firstName: firstName, lastName: lastName)
}
override func getFullName() -> String {
return "\(firstName) \(lastName)"
}
}
let someDoctor = Doctor(firstName: "Sam", lastName: "Smith")
someDoctor.getFullName()

Courses Plus Student 23,888 PointsHi Jeff,
You're right, Xcode will not return errors. This is because you've written perfectly valid code. However, let's take a closer look at the last sentence of the challenge:
'For example, given the first name "Sam", and last name "Smith", calling getFullName() on an instance of Person would return "Sam Smith", but calling the same method on an instance of Doctor would return "Dr. Smith".'
As you can see from your Xcode results, someDoctor.getFullName() is still returning the value "Sam Smith". It should return "Dr. Smith". So while your code is valid, it doesn't achieve the result the challenge calls for.
They key is in adjusting your override function getFullName in the Doctor subclass to return the correct string.
Hope this helps!
