Error with code for enumeration challenge

I'm working on this challenge and I'm pretty sure my code is right, but the challenge keeps telling me I'm making a mistake. These are the errors it's kicking back: "swift_lint.swift:41:1: error: expected declaration ^ swift_lint.swift:25:7: note: in declaration of 'Robot' class Robot { . "

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) {
        // Enter your code below
        switch direction {
        case .up: return location.y += 1
        case .down: return location.y += -1
        case .right: return location.x += 1
        case .left: return location.x += -1
    }
}

Hey Collin,

Quick fix for this one, you're missing a curly brace to close off your Robot class. Add that and you should pass the test.

Good luck!
