Mastering Swift 3 by Jon Hoffman

Key FeaturesDiscover the new features and improvements to Swift 3Get to grips with advanced design patterns and techniques to write smarter, cleaner Swift codeBecome a more fluent Swift developer and build powerful, impressive iOS and OS X applications.Book DescriptionSwift is the definitive language of Apple development today. Its a vital part of any iOS and OS X developers skillset, helping them to build the most impressive and popular apps on the App Store—the sort of apps that are essential to iPhone and iPad users every day. With version 3.0, the Swift team have added new features to improve the development experience—making it easier to get the results you want and customers expect.Inside, youll find the key features of Swift 3.0 and quickly learn how to use the newest updates to your development advantage. From Objective-C interoperability to ARC, to closures and concurrency, this advanced Swift guide will develop your expertise and make you more fluent in this vital programming language. We give you in-depth knowledge of some of the most sophisticated elements of Swift development including protocol extensions, error-handling, design patterns, and concurrency, and guide you on how to use and apply them in your own projects. Youll see how even the most challenging design patterns and programming techniques can be used to write cleaner code and to build more performant iOS and OS X applications. By the end of this book, youll have a handle on effective design patterns and techniques, which means youll soon be writing better iOS and OS X applications with a new level of sophistication and control.What you will learnDive into the core components of Swift 3.0, including operators, collections, control flow, and functionsCreate and use classes, structures, and enumsUnderstand object-oriented Swift and see how to tackle inheritance, protocols, and extensionsDevelop a practical understanding of subscripts, optionals, and closuresSee how to use the new protocol extension and error handling features of Swift 3.0Add concurrency to your applications using Grand Central DispatchAbout the AuthorJon Hoffman has over 20 years of experience in the field of Information Technology. Over those 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 developed extensively for the iOS platform since 2008. This includes several apps that he has published in the App Store, apps that he has written for third parties, and numerous enterprise applications. What really drives Jon is the challenges the Information Technology field provides and there is nothing more exhilarating to him than overcoming a challenge.You can follow Jon on his two blogs: http://masteringswift.blogspot.com and http://myroboticadventure.blogspot.com.Some of Jons 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 have never 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.Table of ContentsTaking the First Steps with SwiftLearning About Variables, Constants, Strings, and OperatorsUsing Swift Collections and the Tuple TypeControl Flow and FunctionsClasses and StructuresUsing Protocols and Protocol ExtensionsProtocol-Oriented DesignWriting Safer Code with Availability and Error HandlingCustom SubscriptingUsing Optional TypesWorking with GenericsWorking with ClosuresUsing Mix and MatchConcurrency and Parallelism in SwiftSwift Formatting and Style GuideSwifts Core LibrariesAdopting Design Patterns in Swift
