Hoffman - Protocol-oriented programming with Swift build fast and powerful applications by exploiting the power of protocol-oriented programming in Swift

Jon Hoffman has over 20 years of experience in the field of information technology. Over these 20 years, Jon has worked in the areas of system administration, network administration, network security, application development, and architecture. Currently, Jon works as a senior software engineer for Syn-Tech Systems.

Jon has been developing extensively for the iOS platform since 2008. This includes several apps that he has published in the app storeapps that he wrote for third parties and numerous enterprise applications.

Packt Publishing published Jon's first book, iOS and OS X Network Programming , in January 2014.

What really drives Jon is the challenges in the Information Technology field and there is nothing more exhilarating to him than overcoming a challenge. Some of Jon's other interests are watching baseball (go Sox) and basketball (go Celtics). Jon also really enjoys tae kwon do where he and his oldest daughter Kailey earned their black belts together early in 2014. Kim (his wife) earned her black belt in December 2014 and his youngest daughter is currently working towards her black belt.

I would like to thank my wonderful wife Kim, without whose support, encouragement, patience, and understanding, this book would never have been written. I would also like to thank my two wonderful daughters Kailey and Kara who have both been my inspiration and driving force since the days they were born.
