Hands-On Design Patterns with Swift

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 codeKey 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 DescriptionSwift 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 forThis 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 the Author 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 ZX Spectrum. He has worked in Swift Objective-C C/C++ Java .Net Ruby Python and in a ton of other languages that he has forgotten the names of. After years of backend development over the past 10 years Giordano has developed extensively for iOS releasing more than 20 apps―apps that he wrote for clients enterprise applications or on his own.
