Why is this Code not Compiling?

It works perfectly in Xcode

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!")
}

}

class Robot: Machine {

override init(){
    super.init()
    self.location = Point(x: 1, y: 1)
}

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
    }
}

}

Hi!

I think the problem is, that you used the super.init before the subclass initializer - try switching them around. The super.init should always be the last thing in the subclass initializers.

I hope that helps :-)
