Book Description

SwiftUI has transformed app development across Apple Platforms, offering developers the power to build seamless user interfaces by just defining the UI design through intuitive Swift code. This book explores SwiftUI’s revolutionary declarative programming approach to assist you in designing UI for Apple devices, ranging from iPhones to Macs, by declaring what the app should look like and what it should do, leaving the heavy lifting to the operating system.

With a hands-on approach, the book immerses you in the fundamentals of SwiftUI and goes on to cover SwiftUI parts that are omitted by most introductory guides. Starting with creating views and modifiers, you’ll progress to more intricate and responsive user interfaces and advanced techniques, gradually working toward building complex apps. Further, this book focuses on the new features in asynchronous programming and architecture patterns to design efficient, modern, and well-structured apps. Finally, you’ll explore the integration of UIkit and SwiftUI and how to run tests for a SwiftUI application.

By the end of the book, you’ll have gained the confidence to harness the full potential of SwiftUI to build professional-grade applications.
