One of the marvelous qualities of iOS devices, which make them such an indispensable part of our lives, is their ability to remember so much stuff: pictures, phone numbers, addresses, appointments, to-do lists, lesson notes, project ideas, keynote presentations, playlists, articles you want to read—the list seems endless. But so far, none of the apps you’ve developed in this book remembers anything. MyStuff starts with an empty list every time you launch it. Wonderland doesn’t even remember what page you were reading. And consider Pigeon, poor Pigeon. Its only task is to memorize one location, and it can’t even do that. You’re going to fix all of that, and more.
