Network Programming With Swift

This is the Rough Cut version of the printed book. Writing networking code has never been easy, but in an era where practically every app is a connected app, these skills are absolutely essential. Apple's networking libraries for iOS and OS X offer complete facilities for creating code to network with websites, databases, and even other devices running your app. Often, however, Apple's documentation doesn't cover the details, subtleties, and scenarios you need to know about. ¿ In Network Programming with Swift, expert network programmer Karl G. Kowalski brings together all the knowledge and code recipes you need to create network-ready apps for iOS or OS X. Kowalski covers crucial issues and new technologies other Apple network programming ignore, especially Apple's valuable new Bluetooth LE support. Wherever network communications requires both a transmitter and a receiver -- as for a Bluetooth contact-sharing app that transmits specific data and expects a custom response -- he walks through implementing both sides. You'll also find expert coverage of data privacy and integrity issues, third-party libraries and tools, and debugging network code. ¿ Kowalski presents most examples in Swift, supporting your migration to Apple's powerful and efficient new language. Wherever necessary for clarity or other reasons, he also provides Objective-C examples. Every example is targeted at iOS 8 and reflects the new Xcode 6 development environment.

Implement object-oriented programming paradigms with Swift 3.0 and mix them with modern functional programming techniques to build powerful real-world applications About This Book Leverage the most efficient object-oriented design patterns in your Swift applications Write robust, safer, and better code using the blueprints that generate objects Build a platform with object-oriented code using real-world elements and represent them in your apps Who This Book Is For This book is for iOS and macOS developers who want to get a detailed practical understanding of object-oriented programming with the latest version of Swift: 3.0. What You Will Learn Write high-quality and easy-to-maintain reusable object-oriented code to build applications for iOS, macOS, and Linux Work with encapsulation, abstraction, and polymorphism using Swift 3.0 Work with classes, instances, properties, and methods in Swift 3.0 Take advantage of inheritance, specialization, and the possibility to overload or override members Implement encapsulation, abstraction, and polymorphism Explore functional programming techniques mixed with object-oriented code in Swift 3.0 Understand the differences between Swift 3.0, previous Swift versions, and Objective-C code In Detail Swift has quickly become one of the most-liked languages and developers' de-facto choice when building applications that target iOS and macOS. In the new version, the Swift team wants to take its adoption to the next level by making it available for new platforms and audiences. This book introduces the object-oriented paradigm and its implementation in the Swift 3 programming language to help you understand how real-world objects can become part of fundamental reusable elements in the code. This book is developed with XCode 8.x and covers all the enhancements included in Swift 3.0. In addition, we teach you to run most of the examples with the Swift REPL available on macOS and Linux, and with a Web-based Swift sandbox developed by IBM capable of running on any web browser, including Windows and mobile devices. You will organize data in blueprints that generate instances. You'll work with examples so you understand how to encapsulate and hide data by working with properties and access control. Then, you'll get to grips with complex scenarios where you use instances that belong to more than one blueprint. You'll discover the power of contract programming and parametric polymorphism. You'll combine generic code with inheritance and multiple inheritance. Later, you'll see how to combine functional programming with object-oriented programming and find out how to refactor your existing code for easy maintenance. Style and approach This simple guide is packed with practical examples of solutions to common problems. Each chapter includes exercises and the possibility for you to test your progress by answering a quiz

The purpose of this book is to provide tools to design and implement network-orientated applications in .NET. It is also a guide for software designers to choose the best and most efficient way to implement mission critical solutions. The book addresses real-world issues facing professional developers, such as using third-party components as opposed in-house development. It differentiates itself from existing .NET publications because it is aimed at experienced professionals and concentrates on practical, ready-to-use information. The book is written in two languages C# and VB.NET, and covers never-before published information on Telephony in .NET and packet-level networking. This is the second book in the Digital Press Software Development Series. Coverage of lower level protocols allows implementation of performance-centric applications Demonstrates the feasibility of developing telephony solutions in-house rather than outsourcing Written in VB.NET and C# to assist readers working in either language Coverage of Email, FTP and the WWW allows implementation of applications in all three areas

This book follows a recipe-based approach that will heavily focus on the code and how to integrate the samples with the reader’s projects.Each recipe consists of one or more methods that you can put directly into your app and use. This book is ideal for developers that want to create network applications for the Apple OS X or iOS platforms. All examples are written in Objective-C using XCode as the IDE. Knowledge of Objective-C and X-Code is essential.

Dive into Combine!Writing asynchronous code can be challenging, with a variety of possible interfaces to represent, perform and consume asynchronous work - delegates, notification center, KVO, closures, etc. Juggling all of these different mechanisms can be somewhat overwhelming. Does it have to be this hard? Not anymore!In this book, you'll learn about Combine - Apple's framework to work with asynchronous events in a unified and reactive way that ensures your app is always up to date based on the latest state of its data.Who This Book Is ForThis book is for intermediate iOS developers who already know the basics of iOS and Swift development but who are interested in taking their app and state management to the next level by learning declarative/reactive programming.You'll also enjoy this book if you're interested in SwiftUI, since many of the reactive capabilities keeping your SwiftUI views up-to-date are built on top of Combine.Topics Covered in Combine: Asynchronous Programming With SwiftWhat & Why: Learn what Combine and reactive programming are, the problems they solve and how you can unify all of your asynchronous pieces of work.Operators: Learn how to compose, transform, filter and otherwise manipulate different pieces of asynchronous work using operators.In Practice: Gain knowledge on various topics and techniques you'll leverage when writing your own real-life apps. You'll then practice these techniques with actual hands-on apps and projects.SwiftUI: Discover how Combine is deeply rooted within SwiftUI, providing it with the ability to reactively update its views based on the state of your app.Advanced Combine: Once you've got a handle on the basics, you'll dive into advanced Combine topics such as Error Handling, Schedulers, and Custom Publishers.By the end of this book, you'll be a pro in building full-fledged apps using Combine's various abilities.
