Overview of this book

– SwiftUI transforms Apple Platform app development with intuitive Swift code for seamless UI design. – Explore SwiftUI's declarative programming: define what the app should look like and do, while the OS handles the heavy lifting. – Hands-on approach covers SwiftUI fundamentals and often-omitted parts in introductory guides. – Progress from creating views and modifiers to intricate, responsive UIs and advanced techniques for complex apps. – Focus on new features in asynchronous programming and architecture patterns for efficient, modern app design. – Learn UIKit and SwiftUI integration, plus how to run tests for SwiftUI applications. – Gain confidence to harness SwiftUI's full potential for building professional-grade apps across Apple devices.

Modern Structured Concurrency

Concurrency does not directly impact SwiftUI, but it is unavoidable as a concept in writing any application that is non-trivial, and as such, I think it is important enough a subject to deserve at least a chapter in this book. Concurrency is a concept that, over time, has become increasingly important in the development of mobile applications. Concurrency is the ability of a system to manage multiple tasks or operations at the same time. With the escalation in task complexity and the need for faster, more efficient processing to provide users with the best experience, the capacity to execute multiple operations concurrently has become progressively more crucial. Historically, programming languages have provided various mechanisms to manage concurrent execution, such as threads, callbacks, and event loops. These approaches, while functional, often lead to writing complicated and error-prone code. Apple has attempted several times to simplify concurrent...
