# I am not too sure where I am getting it wrong.

I am not sure exactly how to write this out. I looked at other answers provided for the same code challenge but I think over the years things have changed so I am not finding anything to help.

Thank you!

test.swift
```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: y += 1
case .down: y -= 1
case .right: x += 1
case .left: x -= 1

}
}
}
```

``` switch direction {

case .up: location.y += 1
case .down: location.y -= 1
case .right: location.x += 1
case .left: location.x -= 1

}
```

As the challenge says, you should change the coordinates of the Robot's location. Because "y", "x" that you provide come out of nowhere.

Moreover, just look for solutions. There are not much of changes in swift 3 and 4.
