someDoctor isn't the Doctor type?

I'm a bit lost here. Xcode can compile my code and it works fine but it does say someDoctor is a string and the website is saying to make sure someDoctor is the Doctor type but I'm not sure what I am missing.

Any help would be appreciated!

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



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

Hey Cameron!

I believe that the code challenge wants you to first declare the constant someDoctor Doctor typed, and then call the someDoctor fullName function.

Try that and you will pass the challenge.

Hope it helps!

Got it! Tried what you said and found it doesn't even want me to call the fullName method, just to override it and leave it be.
