You are printing the break statement and there's a mistake in UP it should be Up Try this

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 = ++location.y
        case "Down":
             location.y = --location.y
        case "Left":
            location.x = --location.x
        case "Right":
            location.x = ++location.x
        default:
            break
        }
    }

Thank you very very very very very very very very very very very very very very much!
