In Xcode, create a new project called Scattered. Make sure that Swift is selected as the Language. You will be using a storyboard in this project, so check Use Storyboards. The project will not be document-based or use Core Data.

Open ViewController.swift and make the following additions:

import Cocoa

class ViewController: NSViewController {

    var textLayer: CATextLayer!
