I would very much like to thank my wonderful wife, Sophie. Without her support and enthusiasm I would not be where I am today or the man I am today. This one paragraph cannot thank her enough but I doubt Packt Publishing will let me write a book to her so it'll have to do. I must also thank my beautiful daughter Evie, she provides a brilliant distraction when I'm taking a break or thinking of what to write or do next.

I must also thank my Mum and Dad, they provided me with computer equipment from an early age, without which I would have never been able to learn how to program. Along with the rest of my family, my brother David, helped to foster a very strong interest in computers and computing. I will never forget when he made our Spectrum flash insults at me on the screen by programming it and it seemed like pure magic.

Dave Mark and Jeff LaMarche wrote the book I learnt iOS development from and without them I would have missed the mobile train completely.

And finally I must thank all of those from the #actionscript IRC channel where I first learned to program. Special thanks goes out to Rob Gibson, Mark Griffin, Glenn Jones, Andreas R?nning, and all the other people from that channel that I haven't mentioned.
