# Stuck

Code Challenge two for Enumeration and Optionals

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) -> Point {
switch direction {
case .up: return Point(x: 0, y: 1)
case .down: return Point(x: 0, y: -1)
case .right: return Point(x: 1, y: 0)
case .left: return Point(x: -1, y: 0)
default: return Point(x: 0, y: 0)
}
}
```

Here is how you would complete this challenge; let me know if you need further explanation

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

}
}
}
```
