I can't figure the correct way to code the switch statement
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! Im a machine!")
}
}
class Robot: Machine {
override init() {
}
override func move(direction: String) {
print("Up")
print("Down")
print("Left")
print("Right")
}
}
// Enter your code below

// Enter your code below
class Robot: Machine {
override func move(direction: String) {
switch direction{
case "Up":
super.location.y += 1
case "Down":
super.location.y -= 1
case "Right":
super.location.x += 1
case "Left":
super.location.x -= 1
default:
break
}
}
}
make sure to switch on direction (a string being either up down left or right) and include a default case in case what is entered is none of the above. super references the machine class where we have location with x and y coordinates.
