Synopsis

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 Features

• Write 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 boost
• Choose patterns such as MVP, MVC, and MVVM depending on the application being built

Book 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 learn

• Work efficiently with Foundation and Swift Standard library
• Understand the most critical GoF patterns and use them efficiently
• Use Swift 4.2 and its unique capabilities (and limitations) to implement and improve GoF patterns
• Improve your application architecture and optimize for maintainability and performance
• Write efficient and clean concurrent programs using futures and promises, or reactive programming techniques
• Use Swift Package Manager to refactor your program into reusable components
• Leverage testing and other techniques for writing robust code

Who 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.

About this title

About the Authors

Florent Vilmart, M.Sc. is a full stack engineer in Montreal. Born in France, he moved to Montreal short before graduating looking for exciting opportunities in the francophone metropole of North-America. He honed his skills with Objective-C before jumping to Swift when it was released. He’s a polyglot, and you can find his open source work on the parse-community GitHub project where he is one of the core maintainers of the multiple projects. He also spoke at conferences like the GithubCodeConf in 2016 and most recently the Swift Summit in 2017. Currently, he is working full time with Swift, Javascript, and Kubernetes and leads a team of 6 engineers.

Giordano Scalzo is a developer with 20 years of programming experience, since the days of the ZX-Spectrum. He has worked in C++, Java, .NET, Ruby, Python, and in a multitude of other languages. After years of backend development, Giordano has developed extensively for iOS, releasing more than 20 apps which he wrote for clients, enterprise applications, or for his own benefit. Currently, he is a contractor in London where, through his company, Effective Code Ltd., he delivers code for iOS. For Packt, he has written two books on Swift, Swift by Example and Swift 2 by Example, and has reviewed a number of Swift books and videos, including Learn Swift by Building Applications, Introduction to Server-Side Swift, and Swift Functional Programming.

Sergio De Simone has been working as a software engineer for over twenty years across a range of different projects and companies, including work environments such as Siemens, HP, and small start-ups. For the last few years, his focus has been on developing mobile platforms and related technologies. He is currently working for BigML, Inc., where he leads iOS and OS X development. Additionally, he likes writing about technology, as well as programming tools, techniques, and languages, with a special focus on Swift evolution, for InfoQ.
