Swift Recap 2: I cannot find the answer

I have looked all over the internet for an answer and still cannot seem to find one that works. My compiler says that nothing is wrong, but I'm still doing something wrong.

robots.swift 
class Point {
    var x: Int
    var y: Int

    init(x: Int, y: Int){
        self.x = x
        self.y = y
    }
}


class Machine {
    var location: Point

    init() {
        self.location = Point(x: 0, y: 0)
    }

    func move(direction: String) {
        print("Do nothing! Im a machine!")
    }
}
class Robot: Machine{

    override init()
    {
        super.init()
        self.location = Point(x: 0, y: 0)
    }
    override func move(direction: String) {
        switch direction{
        case "Up":
            location.y += 1
        case "Down":
            location.y -= 1
        case "Right":
            location.x += 1
        case "Left":
            location.x -= 1

        default: break
        }

    }
}
