This seems completely right to my but the idea is not compiling it because of an issue in the line "class Robot {"

What is happening?

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 .down: location.y -= 1
        case .up: location.y += 1
        case .right: location.x += 1
    }
}

You are missing a closing bracket for this:

func move( _ direction: Direction) {

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