Question

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\'m a machine!")
  }
}

// Enter your code below

class Robot: Machine {
  func Override 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
    }
  }
}

Colton,

First, in the challenge that I am getting now the signature of the move function in the Machine class is func move(_ direction: String). If you didn't modified this, you should report a bug for that challenge, but I would make sure first.

Now the real issue in your code is that when you override the method, the override keyword should first. For example:

override func move(_ direction: String)

Also, override is all lower case, in your code you are writing Override. Fix these issues and let me know anything.

Hope I helped.

Thank you Daniel! I failed to write the signature of the move function correctly. There is no bug, I removed it. Correct answer worked when I wrote the override function as: override func move(_ direction: String)

Thanks again
