Power up your inner game developer and start building incredible games with Sprite Kit. This book will teach you everything you need to know about Apple’s 2D game engine. If you have some programming experience but you’re new to game development, you’ll hit the ground running, no complex tools required—just the Sprite Kit SDK.
You’ll start out fast by building a single-finger infinite runner game, where the goal is to stay alive as long as possible and rack up points. You’ll explore the Sprite Kit template, actions, and particle editor and watch your game take shape with an armed player ship, asteroids and enemy ships, explosions, power-ups, and variable difficulty. Then you’ll stitch the game together with cutscenes, menus, and scoring.
Next, you’ll build a classic pinball game with all the fun and physics of the real thing. You’ll discover the powerful Sprite Kit physics engine and enhance your game with gravity, friction, ricochets, and spin physics, as well as sound effects, bonus scoring, and special effects. Plus, this game features two-finger control.
Dust off those game ideas you’ve been tucking away and let your imagination bring them to life. This book will show you how.

Comments and Reviews
—Daniel H. Steinberg Dim Sum Thinking
This book is your quickest path from creating a new Sprite Kit project in Xcode to shipping an iOS game. Joshua and Jonathan have a great deal of experience creating games with Sprite Kit and teaching the technology in their popular seminar. In this book they show you the fundamentals and help you avoid the gotchas.
—Ash Furrow iOS Developer
I had never written a game before, but with hands-on practice, this book guided me through the basics of how to set up a Sprite Kit app. In detail, it covers how to progress from the basics up to advanced topics, like physics, textures, and frame-based animations. This book is a great way to dip your toes into the exciting new Sprite Kit framework.
—Cesare Rocchi CEO Studio Magnolia
Apple’s documentation for Sprite Kit is pretty good, but it’s not enough. Jonathan and Josh make it easy to understand the concepts behind developing games with Sprite Kit. Throughout the book you will develop two complete games while having fun learning about scenes, sprites, textures, and sounds. Are you building a new game with Sprite Kit? Just buy this book and read it.

As an iOS developer wanting to step into the world of mobile-game development, I really enjoyed reading this book. It’s a great introduction to Sprite Kit, explaining the basics and the more advanced stuff very well.
—Janie Clayton-Hasz iOS developer Digital World Biology LLC
Rather than just telling the reader what to do, Jonathan Penn and Joshua Smith walk the programmer through why they are using a given method or set of numbers. Very few people go to this trouble, which is one big reason this book is a must-read.
—John Moses developer
After reading the book, game development on iOS seems less wizard-like. I would not be surprised if there were a flood of games released on the market due to how easy the authors made it seem.
—Kevin Munc mobile developer and founder Method UP LLC
This is a fun book! Sprite Kit makes it easier than ever to build games for iOS, and these authors know their stuff and know how to get you up and running with it in no time.
—Zak Nixon lead software engineer and CEO Deep Digital LLC
This book was so much fun to read and follow along with that by the time I was done, I had developed a solid grasp of the Sprite Kit APIs plus a fully featured game end-to-end. Well done, Rubber City Wizards!
