I have no clue why this code wont satisfy the challenge, error, you need to provide an implementation for the move method:

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(location: Point) {
self.location = Point(x: 0, y: 0)
}
```

func move(direction: Direction) { // Enter your code below switch direction { case .Up: return location.y += 1 case .Down: return location.y -= 1 case .Right: return location.x += 1 default: return location.x -= 1 } } }

let newRobot = Robot() newRobot.move(direction up)

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(location: Point) {
self.location = Point(x: 0, y: 0)
}

func move(direction: Direction) {
switch direction {
case .Up:
return location.y += 1
case .Down:
return location.y -= 1
case .Right:
return location.x += 1
default:
return location.x -= 1
}
}
}

let newRobot = Robot()
newRobot.move(direction up)
```
