I am having problem with code challenge presented in the below URL:
Below is solution. Could any one please help?
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{
override init() { super.init() self.location = Point(x: 10, y: 10) }
override func move(direction: String){
switch direction{
case "Up": self.location.y = self.location.y++
case "Down": self.location.y++
case "Left": self.location.x--
case "Right": self.location.x++
default: break
}
}
}

Try not overwriting init.
If you still have trouble, try copying your code into an XCode playground and see what errors come up.
