Expected Declaration Error

Question

It seems like the code here should be working, but every time I attempt to compile it I'm coming up with the following error: "swift_lint.swift:37:1: error: expected declaration"

Any help is greatly appreciated!

classes.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) {
        // Enter your code below
       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
        }
}

Hey Arthur Boilanger,

Simple fix. You're missing a bracket to close out your function.

class Point { // open1
    var x: Int
    var y: Int

    init(x: Int, y: Int){ // open2
        self.x = x
        self.y = y
    } // close 1
} // close 2

enum Direction { // open3
    case Left 
    case Right
    case Up
    case Down
} // close3


class Robot { // open4
    var location: Point

    init() { // open5
        self.location = Point(x: 0, y: 0)
    } // close5

    func move(direction: Direction) { // open6
        // Enter your code below
       switch direction { // open7
        case Direction.Up: location.y += 1
        case Direction.Down: location.y -= 1
        case Direction.Right: location.x += 1
        case Direction.Left: location.x -= 1
        } // close7
    } // close6 <--- missing
} //close4
