Software developers need to solve various problems. Many times, these problems are the same or similar to the ones they've already encountered in other projects. Wouldn't it be great to apply the solution you've found instead of reinventing the wheel over and over again? That's precisely the reason why software design patterns exist. A design pattern is a standardized way to address a recurring problem. Relying on a proven strategy will not only save you time, but you can rest assured that it's indeed the right choice. Design patterns are the result of a long evolution process. It all started with a book published in 1994 - yes, it's that old! - called "Design Patterns - Elements of Reusable Object-Oriented Software." That's a quite tedious title, so we usually refer to it as "the book by the gang of four." The gang consists of four renowned software engineers: Erich Gamma, Ralph Johnson, Richard Helm, and John Vlissides. They identified the most significant common issues that occurred in multiple projects and developed best practices to solve them. The best part: these solutions are (programming) language-agnostic. You can use the design patterns with any object-oriented programming language. Many modern programming languages and frameworks have integrated the GoF patterns. You don't have to write additional code to support say the Iterator or the Observer. Swift is no exception: it provides many advanced language features and constructs such as type extensions, lazy initialization, and predefined protocols that let us adopt and integrate the design patterns into our projects easily. This book covers all these topics and teaches best practices you can apply in your upcoming projects. We'll talk about the benefits of understanding and applying the design patterns, the value they provide, and also about their limitations. Then, we delve into the creational design patterns: the Singleton, the Prototype, the Factory Method, the Builder, and the Abstract Factory design pattern We're going to take a closer look at the structural design patterns. We discuss: the Adapter, the Decorator, the Façade, the Flyweight, and the Proxy pattern In the final part of this book, we discuss the behavioral design patterns: the Chain of Responsibility, the Iterator, the Observer, and we finish with the State design pattern For each design pattern, we discuss the following: When to use the specific design pattern? How can it be implemented using Swift 5? What are the challenges and pitfalls of using the given pattern? Throughout the book, I provide coding examples that can be applied in real-world situations.

From learning about the most sought-after design patterns to a comprehensive coverage of architectural patterns and code testing, this book is all you need to write clean, reusable code Key FeaturesWrite clean, reusable and maintainable code, and make the most of the latest Swift version.Analyze case studies of some of the popular open source projects and give your workflow a huge boostChoose patterns such as MVP, MVC, and MVVM depending on the application being builtBook Description Swift keeps gaining traction not only amongst Apple developers but also as a server-side language. This book demonstrates how to apply design patterns and best practices in real-life situations, whether that's for new or already existing projects. You’ll begin with a quick refresher on Swift, the compiler, the standard library, and the foundation, followed by the Cocoa design patterns – the ones at the core of many cocoa libraries – to follow up with the creational, structural, and behavioral patterns as defined by the GoF. You'll get acquainted with application architecture, as well as the most popular architectural design patterns, such as MVC and MVVM, and learn to use them in the context of Swift. In addition, you’ll walk through dependency injection and functional reactive programming. Special emphasis will be given to techniques to handle concurrency, including callbacks, futures and promises, and reactive programming. These techniques will help you adopt a test-driven approach to your workflow in order to use Swift Package Manager and integrate the framework into the original code base, along with Unit and UI testing. By the end of the book, you'll be able to build applications that are scalable, faster, and easier to maintain. What you will learnWork efficiently with Foundation and Swift Standard libraryUnderstand the most critical GoF patterns and use them efficientlyUse Swift 4.2 and its unique capabilities (and limitations) to implement and improve GoF patternsImprove your application architecture and optimize for maintainability and performanceWrite efficient and clean concurrent programs using futures and promises, or reactive programming techniquesUse Swift Package Manager to refactor your program into reusable componentsLeverage testing and other techniques for writing robust codeWho this book is for This book is for intermediate developers who want to apply design patterns with Swift to structure and scale their applications. You are expected to have basic knowledge of iOS and Swift.

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.
