Why is it not working?? Any one?

Cant seem to get this right

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! I am a machine!")
  }
}

// Enter your code below

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

I think you started the code off wrong on your subclass. 'Class' is supposed to be 'class'. Use of lowercase not uppercase. I hope that helps.

it is still not compiling

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 am a machine!") } }

// Enter your code below

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