I don't understand why this won't compile and the errors are useless.
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.y = self.location.y + 1
case "Down":
self.location.y = self.location.y - 1
case "Right":
self.location.x = self.location.x - 1
case "Left":
self.location.x = self.location.x - 1
default:
break
}
}

You're missing a closing bracket for your Robot class. Also, the case for the string "Right" should increase the location's x property — as opposed to decreasing it.
