1,941 PointsObject-Oriented Swift - fullName() override
I see nothing wrong with my code. Works perfect in XCode. Any ideas?
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.") \(firstName) \(lastName)"
}
}
let someDoctor = Doctor.init(firstName: "Sam", lastName: "Smith")

28,558 PointsThe string it produces is not the same as the one the challenge asks for. The challenge asks that the overridden method returns a string that contains "Dr." and the last name of the person, not the fullname.
Like this:
class Doctor: Person {
override func fullName() -> String {
return "Dr. \(lastName)" // Removed firstName
}
}
let someDoctor = Doctor(firstName: "Sam", lastName: "Smith")
I also removed the interpolation around the word "Dr." since it is not needed, and removed the explicit call to init
, as that method is called automatically when you call the Doctor
class.
