Cant compile, pretty sure code is fine though ./

I have written the method as required, but cant check my work, it says it cant be compiled because of something wrong with Robot class, but could not figure it out :((

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) {
        switch direction {
        case .left: location.x -= 1
        case .right: location.x += 1
        case .up: location.y += 1
        case .down: location.y -= 1
    }
}

Hi there! You're doing great, but you've made a tiny omission. Your Robot class is not closed. You start the move function then start a switch statement. The switch has a matching closed curly brace and so does the move function, but the class also needs one. When I add a single closing curly brace to the end of your code (to close the Robot class), your code passes!

Hope this helps! :sparkles:
