iOS Object-Oriented Swift Inheritance Overriding Methods

Hello, I can't seem to pass this challenge. It works in playground but not here...

class RoundButton: Button {
    var cornerRadius: Double = 5.0

    override func incrementBy(points:Double=7.0) {
        super.incrementBy(points)
    }

Hi Adrian,

I think you linked to the wrong challenge. The challenge under Inheritance > Overriding Methods is asking about something else.

The answer for that challenge is.

// Enter your code below

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

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