Imagine going back in time to visit the people who wrote for the original Atari
2600 game console and showing them games on an iPhone. Jaws would drop.
Minds would be blown. They’d probably check for smoke and mirrors.
We’ve come a long way from the video game industry’s humble beginnings.
Writing games was a challenge back then. It still is today, of course, but the
challenges then involved shoving individual pixels around, saving CPU cycles

for rudimentary sounds, and interpreting raw player input from analog joy-
sticks. Today, our challenges are often bounded more by our imaginations

than by technical constraints.
And that’s why we think you’ve joined us here in this book. You have an
unprecedented amount of power in a computer resting in the palm of your
hand. You want to write a game, and you’d like to do it for iOS. We have good
news for you.
Welcome to Sprite Kit! Apple’s exciting 2D-game development engine sports
an excellent API to help bring your 2D game idea from paper to pixels. If you’re
already an iOS developer, then there’s nothing else you need to do. It comes
with excellent Xcode support and gives you a template ready to get started.
It doesn’t get any easier than this.
