7,511 PointsHi Praneeth,
your actually spot on minus one thing. You want to switch on your internal variable (from func move) direction which is of TYPE Direction. You tried to switch on the enum itself.
Here is the code:
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() {
self.location = Point(x: 0, y: 0)
}
func move(_ direction: Direction) {
// Enter your code below
switch direction { //Changed to direction
case .up: location.y += 1
case .down: location.y -= 1
case .right: location.x += 1
case .left: location.x -= 1
}
}
}
