This is the code:
class Robot: Machine { override func move(direction: String) { switch direction { case "Up": self.location = (Point(x: 0, y: 1)) case "Down": self.location = (Point(x: 0, y: -1)) case "Left": self.location = (Point(x: -1, y: 0)) case "Right": self.location = (Point(x: 1, y: 0)) default: break } } }
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!")
}
}
// Enter your code below
class Robot: Machine {
override func move(_ direction: String) {
switch _ direction {
case "Up":
self.location = (Point(x: 0, y: 1))
case "Down":
self.location = (Point(x: 0, y: -1))
case "Left":
self.location = (Point(x: -1, y: 0))
case "Right":
self.location = (Point(x: 1, y: 0))
default: break
}
}
}

13,806 Pointsjust need to remove the underscore after switch, direction is the local argument name used to pass the input argument along to the switch statement
