Essentials of Swift Programming
"Essentials of Swift Programming" "Essentials of Swift Programming" is a comprehensive guide designed to empower both new and seasoned software professionals with a deep understanding of the Swift programming language. Spanning Swift’s language design and evolution, the book meticulously explores foundational topics such as type inference, advanced pattern matching, and memory management, providing a strong conceptual framework that distinguishes Swift from other modern languages. Each chapter offers clear explanations, practical examples, and expert insights, enabling readers to master both the syntactic fundamentals and nuanced intricacies of Swift. As the journey progresses, the book delves into advanced paradigms including functional techniques, protocol-oriented programming, and sophisticated use of generics and abstractions. Readers will learn to implement efficient, expressive code using closures, higher-order functions, and modular protocol-oriented patterns. Special attention is given to memory safety, performance optimization, and concurrent programming, with dedicated sections on Swift’s concurrency model, safe memory practices, data isolation, and real-world debugging strategies. Beyond core language features, this book also addresses practical challenges faced in modern Swift development. Readers are equipped with in-depth techniques for building robust collections and algorithms, integrating Swift seamlessly with Objective-C and C, and managing external dependencies with the Swift Package Manager. The final chapters focus on real-world best practices—from automated testing and performance monitoring to maintainable API design and effective documentation—making "Essentials of Swift Programming" an invaluable reference for anyone striving to write efficient, scalable, and future-proof Swift code.
SwiftUI Essentials - iOS Edition
The goal of this book is to teach the skills necessary to build iOS 13 applications using SwiftUI, Xcode 11 and the Swift 5 programming language. Beginning with the basics, this book provides an outline of the steps necessary to set up an iOS development environment together with an introduction to the use of Swift Playgrounds to learn and experiment with Swift. The book also includes in depth chapters introducing the Swift 5 programming language including data types, control flow, functions, object-oriented programming, property wrappers and error handling. An introduction to the key concepts of SwiftUI and project architecture is followed by a guided tour of Xcode in SwiftUI development mode. The book also covers the creation of custom SwiftUI views and explains how these views are combined to create user interface layouts including the use of stacks, frames and forms. Other topics covered include data handling using state properties and both observable and environment objects, as are key user interface design concepts such as modifiers, lists, tabbed views, context menus and user interface navigation. The book also includes chapters covering graphics drawing, user interface animation, view transitions and gesture handling. Chapters are also provided explaining how to integrate SwiftUI views into existing UIKit-based projects and explains the integration of UIKit code into SwiftUI. Finally, the book explains how to package up a completed app and upload it to the App Store for publication. Along the way, the topics covered in the book are put into practice through detailed tutorials, the source code for which is also available for download. The aim of this book, therefore, is to teach you the skills necessary to build your own apps for iOS 13 using SwiftUI. Assuming you are ready to download the iOS 13 SDK and Xcode 11 and have an Intel-based Mac you are ready to get started.
SwiftUI Essentials - iOS 15 Edition
The goal of this book is to teach the skills necessary to build iOS 15 applications using SwiftUI, Xcode 13 and the Swift 5.5 programming language. Beginning with the basics, this book provides an outline of the steps necessary to set up an iOS development environment together with an introduction to the use of Swift Playgrounds to learn and experiment with Swift. The book also includes in-depth chapters introducing the Swift 5.5 programming language including data types, control flow, functions, object-oriented programming, property wrappers, structured concurrency, and error handling. An introduction to the key concepts of SwiftUI and project architecture is followed by a guided tour of Xcode in SwiftUI development mode. The book also covers the creation of custom SwiftUI views and explains how these views are combined to create user interface layouts including the use of stacks, frames and forms. Other topics covered include data handling using state properties in addition to observable, state and environment objects, as are key user interface design concepts such as modifiers, lists, tabbed views, context menus, user interface navigation, and outline groups. The book also includes chapters covering graphics drawing, user interface animation, view transitions and gesture handling, WidgetKit, document-based apps, Core Data, CloudKit, and SiriKit integration. Chapters are also provided explaining how to integrate SwiftUI views into existing UIKit-based projects and explains the integration of UIKit code into SwiftUI. Finally, the book explains how to package up a completed app and upload it to the App Store for publication. Along the way, the topics covered in the book are put into practice through detailed tutorials, the source code for which is also available for download. The aim of this book, therefore, is to teach you the skills necessary to build your own apps for iOS 15 using SwiftUI. Assuming you are ready to download the iOS 15 SDK and Xcode 13 and have an Apple Mac system you are ready to get started.
