Dont see what is wrong with my code..

My code wont pass the test, and I just do not see what is wrong with it...

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 func move(direction: String) {
        switch direction {
        case "Up": location.y += 1
        case "Down": location.y -= 1
        case "Left": location.x -= 1
        case "Right": location.x += 1
        default: break
        }
    }
}

It is a very small mistake Alex Budke, when you overwrote the function, you forgot to keep the underscore (which omits the external name). That is all. Keep in mind with these challenges, that in real world situation it is upto you to write functions however you like, but the challenge editor is not forgiving.
