Donny Wals is a passionate, curious, developer from The Netherlands. Ever since he started his communications and multimedia design studies in Amsterdam, he knew that he didn't just want to build great websites and apps, but also transfer knowledge to his peers and newcomers. He got involved with coaching, mentoring, and assisting in his freshman year.

During his final two years at college, he's been a teacher in web development and spent most of his free time exploring iOS and Objective-C. When Swift was first announced, it didn't take long for him to start playing around with it, and after just a few months of learning and experimenting Donny became the lead iOS developer for the start-up where he'd been working at the time.

As an active member of the iOS-developers Slack community, Donny is always up for helping out people with their code and sharing his own knowledge with his peers.

Alexandre Freire is the reviewer of this book. He is a Spanish iOS developer and the author of several software development courses. At the young age of 26, Alexandre sold his own startup (Apparcar). When he is not coding, you can usually find him supporting Deportivo de A Corua--his favourite football team--or exploring the most beautiful landscapes of Galicia with his family. You can connect to Alexandre on Twitter at @xandrefreire.

When Apple launched Swift in 2014, the iOS ecosystem became more accessible than it had ever been for developers. Being able to write apps with Swift's beautiful, readable, and straightforward syntax instead of having to write clunky Objective-C code suddenly enabled a lot of people to play around with iOS development. For me, Swift sparked a renewed interest in developing iOS applications, and the new passion has remained ever since.

This book will hopefully transfer some of that passion to you. This book is written to match my personal preferred way of learning, which is learning by doing. In this book, you'll find examples of applications that you might actually want to build some day. The problems that are tackled in this book are real and practical. This book doesn't cover every single framework that you can use in your apps; there are simply way too many. Instead, the focus is on understanding how you can navigate Apple's documentation, how you can refactor your code, and how you can solve real-world development problems.
