"To Rachael. For putting up with me whilst I spent nights and weekends behind my laptop writing. To my family, for being there for me always."

Darryl Bayliss

"To my wife Tracy, for her love and understanding while I worked many late nights and weekends. To my son Austin for his support and many corrections to my rough drafts. To my daughter Alaina, for her beautiful smiles and encouragement. To my parents who bought my first Atari computer and set me on this great journey."

Tom Blankenship

"To my parents, who took care of me when I was small. To my children, the apples of my eyes, who provided the light when it was dark and the inspiration to keep going. To my wife, for putting up with me. To Ray Wenderlich, and the entire Ray Wenderlich team, for establishing the gold standard for quality content and writing and showing me the way its done."
