There are no compilation errors but while rechecking the work it's giving the error like "In the up direction increase the y coordinate by 1", but in the code it already increased
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 .left:
location.x - 1
case .right:
location.x + 1
case .up:
location.y + 1
case .down:
location.y - 1
}
}
}

4,025 Pointsyou should change the value of location, in your code you are making an operation, but you are nota assigning the result to any variable.
func move(_ direction: Direction) { switch direction { case .left: location.x = location.x - 1 case .right: location.x = location.x + 1 case .up: location.y = location.y + 1 case .down: location.y = location.y - 1
}
