I don´t know how to do this code challenge
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! I'm a machine!")
}
}
// Enter your code below
class Robot: Machine {
override func move(_ direction: String) {
switch move {
case "Up": location.y += 1
case "Down": location.y -= 1
case "Left": location.x -= 1
case "Right": location.x += 1
default: break
}
}
}
