About the authors

Janie Clayton is an independent iOS developer. She spent a year apprenticed to a super genius programming robots and learning the forgotten ways of long term software maintenance and development. Janie is the coauthor on several books on iOS and Swift development. Janie lives outside of Madison, Wisconsin with her attempted grumble of pugs and multitude of programming books. Janie writes her various musings on her blog at RedQueenCoder.com.

Alexis Gallagher is a software engineer who is always looking for the conceptual deep dive and always hoping to find pearls down at the bottom. When he’s not coding, he’s out and about in sunny San Francisco.

Matt Galloway is a software engineer with a passion for excellence. He stumbled into iOS programming when it first was a thing, and has never looked back. When not coding, he likes to brew his own beer.

Eli Ganem is an engineer at Facebook. He is passionate about teaching, writing, and sharing his knowledge with others.

Erik Kerber is a software developer in Minneapolis, MN, and the lead iOS developer for the Target app. He does his best to balance a life behind the keyboard with cycling, hiking, scuba diving, and traveling.

Ben Morrow delights in discovering the unspoken nature of the world. He’ll tell you the surprising bits while on a walk. He produces beauty by drawing out the raw wisdom that exists within each of us.

Cosmin Pupăză is a software developer and tutorial writer from Romania and this is his first book. He is part of the Swift tutorial teams at AppCoda and raywenderlich.com. He has worked with more than a dozen programming languages, technologies, frameworks, tools and libraries over the years, but none of them has made such a great impact on himself as the advent of Swift. When not coding, he either plays the guitar or studies WWII history, and he hopes you enjoy reading the book just as much as he enjoyed writing it. Cosmin blogs about Swift at cosminpupaza.wordpress.com.
