Build robust and scalable iOS and Mac OS X game applications About This Book * Learn to use and implement the 23 Gang of Four design patterns using Swift 2 * Design and architect your code for Swift application development * Understand the role, generic UML design, and participants in the class diagram of the pattern by implementing them in a step-by-step approach Who This Book Is For This book is intended for competent Swift developers who want to apply enduring design patterns with Swift to structure and scale their application code. What You Will Learn * Choose the appropriate pattern depending on the problem to be solved * Understand the generic class diagram of each of the 23 GoF patterns and how each object participates in the pattern * Use Swift to implement these patterns even though the language doesn't provide all of the object-oriented programming concepts such as abstract class, interface, and so on * Architect your software to avoid the overuse of memory, time spent on calculations, or high network traffic * Find the best way to organize your code to make it more secure from the outside world * Prepare your code to make it more flexible when the consumer changes or the third-party component hidden code changes * Structure your code to change the algorithm to apply at runtime * Deliver Flyweight responsibility to your objects In Detail Swift is a multi-paradigm language. It has expressive features familiar to those used to work with modern functional languages, while also keeping the object-oriented features of Objective-C. It remains compatible with Apple's legacy codes and frameworks. A design pattern systematically names, motivates, and explains a general design that addresses a recurring design problem in object-oriented systems. It describes the problem, the solution, when to apply the solution, and its consequences. It also gives implementation hints and examples. Knowledge about design patterns is also one of the best ways to make you different compared to other low-level developers. This book shows you how to use Swift 2 to learn about 23 Gang of Four (GoF) design patterns, and is organized into three categories. The book will present you the five creational patterns, followed by the seven structural patterns, and finishing with the 11 behavioral patterns as defined by the GoF. Each chapter will introduce the pattern by defining its role, which common problems the pattern should be used for, its generic UML representation, how each objects presented in the class diagram participate in the pattern, and what the role of each of these objects is. The book then presents you with a concrete case as an illustration that will be used to implement the pattern using Swift. Style and approach A step-by-step tutorial completed with screenshots and code highlights wherever necessary. Each chapter discusses one or more patterns with its definitions and a simple-to-follow illustration case using a playground or XCText project to implement it with Swift.

Get to grips with object-oriented programming in Swift to efficiently build powerful real-world applications About This Book * Leverage the most efficient object-oriented design patterns in your Swift applications * Write robust, safer, and better code using the blueprints that generate objects * Build a platform with object-oriented code by using real-world elements and represent them in your app Who This Book Is For If you are an iOS developer who has a basic idea of object-oriented programming and want to incorporate its concepts with Swift to optimize your application's code and create reusable and easily to understand building blocks, then this book is for you. This is a very useful resource for developers who want to shift from Objective C, C#, Java, Python, JavaScript, or other object-oriented languages to Swift What You Will Learn * Build solid, stable, and reliable applications using Swift * Work with encapsulation, abstraction, and polymorphism using Swift 2.0 * Customize constructors and destructors based on your needs * Develop Swift 2.0 with classes, instances, properties, and methods * Take advantage of generic code to maximize code reuse and generalize behaviors * Use state of inheritance, specialization, and the possibility to overload members * Write high quality object-oriented code to build apps for iOS or Mac OS X In Detail Object-Oriented Programming (OOP) is a programming paradigm based on the concept of objects; these are data structures that contain data in the form of fields, often known as attributes and code. Objects are everywhere, and so it is very important to recognize elements, known as objects, from real-world situations and know how they can easily be translated into object-oriented code. Object-Oriented Programming with Swift is an easy-to-follow guide packed full of hands-on examples of solutions to common problems encountered with object-oriented code in Swift. It starts by helping you to recognize objects using real-life scenarios and demonstrates how working with them makes it simpler to write code that is easy to understand and reuse. You will learn to protect and hide data with the data encapsulation features of Swift. Then, you will explore how to maximize code reuse by writing code capable of working with objects of different types. After that, you'll discover the power of parametric polymorphism and will combine generic code with inheritance and multiple inheritance. Later, you move on to refactoring your existing code and organizing your source for easy maintenance and extensions. By the end of the book, you will be able to create better, stronger, and more reusable code, which will help you build better applications. Style and approach This simple guide is packed with practical examples of solutions to common problems. Each chapter includes exercises and the possibility for you to test your progress by answering questions.
