Acknowledgements
Huge thanks to Dave Moser and Scott Kelby at Kelby Media Group for allow-
ing me to perfect my craft and grow as an iOS developer with their team,
and to Scott for taking the time to write the foreword for this book. I really
appreciate the advice and support they’ve given me over the years.
Thanks to Matt Kloskowski, Dave Cross, RC Concepcion, Corey Barker,
Paul Wilder, Erik Kuna, Tommy Maloney, and the rest of the ne folks at
NAPP for providing valuable feedback on earlier versions of some of my apps.
Thanks as well to Nancy Massé for always being helpful and for rst intro-
ducing me to Dave Moser and Scott Kelby.
Thanks to Scott Cowlin, who rst supported my crazy idea of writing a tech-
nical book targeted at designers, and to Michael Nolan, Margaret Anderson,
Gretchen Dykstra, and the rest of the staff at Peachpit Press for helping
me turn that idea into an incredible text. Thanks to Scott “Fish” Fisher,
my tech editor, whose attention to detail in the code blocks caught even the
smallest typo.
A very special thanks to Alan Cannistraro, Evan Doll, Stanford University,
and Apple for teaching and encouraging me and other iOS developers, and
for making their courses, lectures, and learning material available for free
online.
Thanks to Cholick for being a daily sounding board for my half-baked notions
and crazy ideas for nearly four years.
I’m grateful to my parents, Dave and Kelly Welch, as well as my brothers and
their families—Eric and his wife, Gretchen; Danny and his wife, Katie; and
Kyle—for keeping me humble and reminding me of the humor in life.
And, of course, thank you to everyone who uses my apps, my Twitter follow-
ers, my Facebook friends, and NAPP members across the globe. The success
of an iOS designer/developer comes from experience; your feedback combined
with your daily use of my apps gave me the experience I needed to write this
book. Thank you.
