Error with exercise

The function at the bottom of the code, on the print line, it is commented out. There are two " to form a string. The "I'm" portion of the line is not formatted properly. This is where the program glitches. This causes the rest of the code to be commented out.

How do I fix this so that I can complete this exercise?

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

I too see that the code is being commented out after the last function. While visually it's commented out, the compiler is still functioning and allowing me to complete the challenge with my Robot class.

That's odd. I tried it and it work. You're correct. The compiler is functioning.
