At the time of writing this book, I was fortunate to work with an excellent team at Packt Publishing, whose contributions vastly improved the presentation of this book. Reshma Raman allowed me to provide her with ideas to write an updated edition of Object-Oriented Programming with Swift 2 to cover Swift 3, and I jumped into the exciting project of teaching Object-Oriented Programming in the most promising programming language developed by Apple: Swift 3.

Vikas Tiwari helped me realize my vision for this book and provided many sensible suggestions regarding the text, format, and flow. The reader will notice his great work. Vikas took the great work Divij Kotian had done in the previous edition and helped me in this new edition. It’s been great working with Reshma and Vikas in another project and I can’t wait to work with them again. I would like to thank my technical reviewers and proofreaders for their thorough reviews and insightful comments. I was able to incorporate some of the knowledge and wisdom they have gained in their many years in the software development industry. This book was possible because they gave valuable feedback. The entire process of writing a book requires a huge amount of lonely hours. I wouldn’t be able to write an entire book without dedicating some time to play soccer against my sons, Kevin and Brandon, and my nephew, Nicolas. Of course, I never won a match; however, I did score a few goals.
