Courses Plus Student 2,833 PointsCan's figure this one out. I need help :D
I would appreciate some help. I am very stuck on this question. Tried this code from some other tree house discussions after getting very frustrated with my own code which was not working. :D
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 func move(direction: String) {
switch(direction) {
case "Up":
self.location.y++
case "Down":
self.location.y--
case "Left":
self.location.x--
case "Right":
self.location.x++
default:
break
}
}

There are no ++ or -- operators in Swift. Change those to something like += or -= and you should be able to pass the Challenge ;)
