Overriding Methods Swift 2.0. Code breaks "Check Work" after "Preview"

Course: Object-Oriented Swift - Class Inheritance - Challenge: Overriding Methods

I thought it would be quite easy if I just add a new constant named title and return that along with the lastName. So it looked like this.

class Doctor: Person{
    var title: String

    init(title: String, firstName: String, lastName: String){
        self.title = title
        super.init(firstName: firstName, lastName: lastName)
    }

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

in the playground everything was fine, but when I pasted it in I only got the "Bummer!". If I was restless and pushed the button too often I even crashed the thing.

Here is a screenshot of the "Bummer"

Only possibility was to "dumb it down" and it worked.

class Doctor: Person{
    override init(firstName: String, lastName: String){
        super.init(firstName: firstName, lastName: lastName)
    }

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

My question is now, if there was a mistake or any other person with the same problem.
