Is the way I override fullName wrong? I got correct result in Xcode

Hi,

I tried this in xcode it works. I dont know why this doesnt work on the challenge code playground. is the way I override func getFullName wrong?

please advice

Thank you in advance

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 {

    override init(firstName: String, lastName: String) {
    super.init(firstName: "Dr.", lastName: "Smith")

    }

}

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

Hey, your override ist wrong here. As mentioned in the question, you have to override the getFullName() method, not the init() method as you did.

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

then you are abled to call the method on an instance of Doctor and it should work for you.
