I have no clue why this code wont satisfy the challenge, error, you need to provide an implementation for the move method:
class Point { var x: Int var y: Int
init(x: Int, y: Int) {
self.x = x
self.y = y
}
}
enum Direction { case left case right case up case down }
class Robot { var location: Point
init(location: Point) {
self.location = Point(x: 0, y: 0)
}
func move(direction: Direction) { // Enter your code below switch direction { case .Up: return location.y += 1 case .Down: return location.y -= 1 case .Right: return location.x += 1 default: return location.x -= 1 } } }
let newRobot = Robot() newRobot.move(direction up)
class Point {
var x: Int
var y: Int
init(x: Int, y: Int) {
self.x = x
self.y = y
}
}
enum Direction {
case left
case right
case up
case down
}
class Robot {
var location: Point
init(location: Point) {
self.location = Point(x: 0, y: 0)
}
func move(direction: Direction) {
// Enter your code below
switch direction {
case .Up:
return location.y += 1
case .Down:
return location.y -= 1
case .Right:
return location.x += 1
default:
return location.x -= 1
}
}
}
let newRobot = Robot()
newRobot.move(direction up)

4,548 PointsIt's all about the name of the cases in your move function. You need to make sure they match up with the values in your Direction enum exactly. Check the letter casing of the values you are switching on.
Other than that, you're spot on!
