I'm overriding the function, not understanding why it isn't working?

Maybe I'm doing this wrong? Having a hard time understanding these instructions.....

classes.swift 
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)"
    }

// Enter your code below
class Doctor: Person {
    let someDoctor: String = "Dr."

    override init(firstName: String, lastName: String) {
        super.init(firstName: firstName, lastName: lastName)
    }
    override func getFullName() -> String {
        return "\(someDoctor) \(lastName)"
    }
    }
    }

You worked too hard. They just wanted you to override the function, and then call it on a Doctor object:

class Doctor: Person {

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

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

Caught me again! Thanks Jcorum! I think I had the right Idea, I just was implementing it in the wrong way.

You are welcome. Note that since there are no new stored properties in Doctor there's no need for an initializer.
