Need help

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 .Down: self.location.y -= 1
            case .Left: self.location.x -= 1
            case .Up: self.location.y += 1
            case .Right: self.location.x += 1

You are missing a closing parenthesis for the switch statement.
