Key FeaturesLeverage the most efficient object-oriented design patterns in your Swift applicationsWrite robust, safer, and better code using the blueprints that generate objectsBuild a platform with object-oriented code using real-world elements and represent them in your appsBook DescriptionSwift has quickly become one of the most-liked languages and developers de-facto choice when building applications that target iOS and macOS. In the new version, the Swift team wants to take its adoption to the next level by making it available for new platforms and audiences.This book introduces the object-oriented paradigm and its implementation in the Swift 3 programming language to help you understand how real-world objects can become part of fundamental reusable elements in the code. This book is developed with XCode 8.x and covers all the enhancements included in Swift 3.0. In addition, we teach you to run most of the examples with the Swift REPL available on macOS and Linux, and with a Web-based Swift sandbox developed by IBM capable of running on any web browser, including Windows and mobile devices.You will organize data in blueprints that generate instances. Youll work with examples so you understand how to encapsulate and hide data by working with properties and access control. Then, youll get to grips with complex scenarios where you use instances that belong to more than one blueprint. Youll discover the power of contract programming and parametric polymorphism. Youll combine generic code with inheritance and multiple inheritance. Later, youll see how to combine functional programming with object-oriented programming and find out how to refactor your existing code for easy maintenance.What you will learnWrite high-quality and easy-to-maintain reusable object-oriented code to build applications for iOS, macOS, and LinuxWork with encapsulation, abstraction, and polymorphism using Swift 3.0Work with classes, instances, properties, and methods in Swift 3.0Take advantage of inheritance, specialization, and the possibility to overload or override membersImplement encapsulation, abstraction, and polymorphismExplore functional programming techniques mixed with object-oriented code in Swift 3.0Understand the differences between Swift 3.0, previous Swift versions, and Objective-C codeAbout the AuthorGaston C.
