Can someone please explain to me what I am doing wrong with my code here??
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 am a machine!")
}
}
// Enter your code below
class Robot: Machine{
override func move(_ direction: String) {
switch direction {
case "Up": return Machine.init().location.y += 1
case "Down": return Machine.init().location.y -= 1
case "Left": return Machine.init().location.x -= 1
case "Right": return Machine.init().location.x += 1
default: move(" ")
}
}
}

iOS Development with Swift Techdegree Graduate 30,149 PointsRobot is already a subclass of Machine so you just need to access it with 'location'.
class Robot: Machine{
override func move(_ direction: String) {
switch direction {
case "Up": return location.y += 1
case "Down": return location.y -= 1
case "Left": return location.x -= 1
case "Right": return location.x += 1
default: move(" ")
}
}
}
