Can't solve a code challenge

On Xcode it works but here it says "Bummer! Double check the implementation of the overridden method to match the directions specified"

objects.swift 
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 "Dr.\(firstName)"
    }

}

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

You don't need to override the init method!

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)"
    }
}

class Doctor: Person {
    override func fullName() -> String {
        return "Dr. \(lastName)"
    }
}
let someDoctor = Doctor(firstName: "Kristof", lastName: "Kocsis")
someDoctor.fullName()
// Enter your code below
