# Need help not sure how to figure out the wording

func move( direction: Direction) { // Enter your code below switch(direction) { case Direction.up: location.y += 1

```    case Direction.down: location.y -= 1

case Direction.left: location.x -= 1

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) {

Hi Tim, I believe you've made the tiniest mistake (you'll probably kick yourself once you realise). So after the word "switch" you've put "direction" in parentheses. Remove them and the code should work! - Hope this helps :)

it says now You need to provide an implementation for the move method

Oh, ok. Would you be able to paste in the code you're now trying to use?

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 Direction.up: location.y += 1

case Direction.down: location.y -= 1

case Direction.left: location.x -= 1

case Direction.right: location.x += 1

}}}
```

This is the code I'm using now

Hmmm.. strange..

This is what I have:

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

Awesome that work Thanks. I removed the underscore thought was old syntax but didt need to do that Thanks again

Haha! I didn't know if you had or it was the forum pulling it out of what you copied in.. I've had that happen to me a few times. No worries Tim :)

Happy coding!
