3,868 PointsWhat does the the move(_ direction: Direction) method output? Why does it still work without one?
I am trying to figure out what the function is supposed to output, i thought it would be -> Point or location but those dont seem to work. But when i complete the function with the output being empty it still works somehow anyway, why is this?
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
}
}

6,204 PointsIt shouldn't output anything. It should only change the values of Robot
func move(_ direction: Direction) /* -> nil/void/zip/nada */ {
switch direction
case right: location.x += 1
//You can do the rest from here.
}
