Maybe you’re not setting out to make the next “Angry Birds.” But there are lessons to learn from mobile game design principles– from user training and motivation strategies to fun and engaging graphics– that are valuable to a wide variety of apps. First we’ll glance at a little “theory” about what makes games fun. Then we’ll come back to our non-game apps and see how those concepts could apply. Next, we’ll dive into an introductory example using iOS 7′s new, easy-to-use SpriteKit framework to make a fun, interactive app menu. Finally, we’ll use Instruments in Xcode to check on our frame rate to make sure we’re not compromising performance.
