About the Author

Jorge Jordán is an iOS indie developer who has been passionate about how things work since his childhood. This is the reason why he graduated in Computer Science and became a Java developer. After buying his first iPhone, he became deeply interested in its technology and spent his spare time learning how to develop apps for Apple smartphones.

Over time, he founded Insane Platypus Games (http://insaneplatypusgames.com/) where he tries to make his dreams and games come true. He is also a member of the tutorial team at http://www.raywenderlich.com/.

In his free time, he loves to play video games and bass guitar, and to watch TV series.

I would like to thank my girlfriend, Angélica, for being so patient and for her support while I was spending almost all of my spare time writing this book. Also, I would like to thank my family, especially my mom and my brother, for always believing in me; it is thanks to them that I am the person I am.

Thanks to Vane (<[email protected]>) for creating all the art for this book ...
