792 PointsYou need to provide an implementation for the move method
Why does this say "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() {
self.location = Point(x: 0, y: 0)
}
func move(direction: Direction) {
switch direction {
case .up: location.y += 1
case .down: location.y -= 1
case .right: location.x += 1
case .left: location.x -= 1
}
print(location.x, location.y)
}
}
let player = Robot()
player.location = Point(x: 33, y: 2)
player.move(direction: .up)
player.move(direction: .down)

func move(_ direction: Direction) {
