This book would not have been possible without the support of the team at John Wiley and SonsAaron Black, Christina Haviland, Nancy Rapoport, and Mariann Barsolo. I would also like to thank Chaim Krause for taking the time to read the entire manuscript and his keen eye for detail. It has been my privilege to work with you. Thank you.

When I first began learning iOS development, I started out like most developers, from the humble Hello World application. I was overwhelmed with new concepts, such as view controllers and table views. My background with C++ did not help much when it came to working with Objective-C, and I had to start from scratch. There was no book written on the subject and everything had to be learned from Apple's documentation and personal blogs.

Eventually I came to grips with Objective-C, and with practice, I grew more proficient. With the launch of iOS 7, Apple announced a new language called Swift, and it felt almost like going back to square one again, as I learned how to perform familiar tasks with a new language.

This book is written to help someone new to iOS development learn the basic concepts and (I hope) avoid making the mistakes I made when starting out myself. That being said, this book should also be useful for an experienced Objective-C developer who is looking to transition over to Swift. This book adopts a hands-on Try It approach, and you get to try out each new concept as you progress through the book.

iOS application development is a huge topic, and it is just not possible to include every single topic related to iOS application development in this book. When selecting topics to include in this book, I have tried to strike a balance between the absolute basics and more advanced topics such as Test Driven Development, CloudKit, and UI testing.
