2,846 PointsYour brackets are incorrect. You are missing a closing brace and end up trying to create an instance of the Robot in the Robot class itself. Please check again. This should work
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 {
case .left: return location.x -= 1
case .right: return location.x += 1
case .up: return location.y += 1
case .down: return location.y -= 1
}
}
}
var newRobot = Robot()
newRobot.move(.up)
