Overriding function

Not sure why I am not doing it right ... some flaws

Challenge Task 1 of 1

In the editor you've been provided with two classes - Point to represent a coordinate point and Machine. The machine has a move method that doesn't do anything because most machines are motionless.

Your task is to subclass Machine and create a new class named Robot. In the Robot class, override the move method and provide the following implementation. If you enter the string "Up" the y coordinate of the Robot's location increases by 1. "Down" decreases it by 1. If you enter "Left", the x coordinate of the location property decreases by 1 while "Right" increases it by 1.

Note: If you use a switch statement you can use the break statement in the default clause to exit the current iteration.

    func move(direction: String) {
        print("Do nothing! I'm a machine!")

// Enter your code below

    self.location = break
    var up = (y + 1)
    var down = (y - 1)
    var left = (x - 1)
    var right = (x + 1)
