Develop UI-heavy applications more easily, faster, and error-free. Based on several enhancements to the Swift language, SwiftUI takes a declarative approach to building UIs. Instead of imperatively coding the UI, this book will show you how to describe how you want your UI to look. SwiftUI treats the UI as a function of its state, thereby making managing your app's state a lot easier. Change the underlying data model to redraw all parts of the UI that are connected to that particular slice of data. Likewise, easily update the underlying data model from the UI elements your data model is connected to. Combine is Apple's Functional Reactive Programming framework. It complements SwiftUI and other frameworks, such as the networking APIs, in a natural way. Using Combine, you can subscribe to events and describe data processing in a way that is free of side effects. This allows for an easier implementation of event-driven applications. Using SwiftUI and Combine build more error-free apps in a shorter amount of time, targeting all of Apple's platforms (iOS, iPadOS, watchOS, macOS, tvOS) with little to no overhead. By the end of the book you will have a solid understanding for architecting and implementing UI-heavy apps in a declarative and functional reactive way using SwiftUI, Combine, and async/await. You will: - Build simple and gradually more complex UIs in SwiftUI - Understand SwiftUI's state management system - Work with Combine and Swift's new async/await APIs to access the network and access other asynchronous APIs - Architect and structure modern applications on Apple platforms using SwiftUI, Combine, and async/await

Working effectively with Apple platforms at a corporate or business level includes not only infrastructure, but a mode of thinking that administrators have to adopt to find success. A mode of thinking that forces you to leave 30 years of IT dogma at the door. This book is a guide through how to integrate Apple products in your environment with a minimum of friction. Because the Apple ecosystem is not going away. You'll start by understanding where Apple, third-party software vendors, and the IT community is taking us. What is Mobile Device Management and how does it work under the hood. By understanding how MDM works, you will understand what needs to happen on your networks in order to allow for MDM, as well as the best way to give the least amount of access to the servers or services that's necessary. You'll then look at management agents that do not include MDM, as well as when you will need to use an agent as opposed to when to use other options. Once you can install a management solution, you can deploy profiles on a device or you can deploy profiles on Macs using scripts. With Apple Device Management as your guide, you'll customize and package software for deployment and lock down devices so they're completely secure. You'll also work on getting standard QA environments built out, so you can test more effectively with less effort. This thoroughly revised and expanded Second Edition provides new coverage and updates on daemons and agents, declarative management, Gatekeeper, script options, SSO tools, Azure/Apple Business Essentials integrations and much more. You will Deploy profiles across devices effectively and securely Install apps remotely both from the app store and through custom solutions Work natively with Apple environments rather than retrofitting older IT solutions Who This Book Is ForMac administrators within organizations that want to integrate with the current Apple ecosystem, including Windows administrators learning how to use/manage Macs, mobile administrators working with iPhones and iPads, and mobile developers tasked with creating custom apps for internal, corporate distribution.

It's tedious and time-consuming to create OS-specific versions of every desktop application, especially with different set of tools for each platform. NW.js radically simplifies desktop development, providing a true cross-platform development stack built on HTML, CSS and JavaScript, Node.js modules, and the Chrome Blink engine. NW.js applications interact with the host operating system just like any other platform-native project, so developers have full access to all local files and resources. The performance is great, and best of all, it saves developers time because they only have to write one version of their application. Cross-Platform Desktop Applications guides readers step-by-step as they learn to develop NW.js desktop applications that run on Windows, OSX and Linux. They begin by getting the big picture of what NW.js can (and can't) do. Readers test drive NW.js as they build their first desktop application. Next, they find out how to take advantage of OSspecific features like menus, system-tray apps, clipboards, and the file system. Along the way, this book teaches how to debug errors and diagnose performance bottlenecks with NW.js's browser developer tools, package an application as a standalone executable for each OS, and even distribute it to various app stores. The book gives developers the inspiration and skills they need to code pro quality desktop applications using the web languages they already know. Key features: Step-by-step lessons Package and distribute application to a variety of app stores Develop pro quality desktop applications with web languages AUDIENCE Written for web designers and developers familiar with HTML, CSS, and JavaScript. No desktop app development experience required. ABOUT THE TECHNOLOGY NW.js radically simplifies desktop development, providing a true crossplatform development stack built on HTML, CSS and JavaScript, Node.js modules, and the Chrome Blink engine.

Discover what tools there are for unit testing in iOS, and how to work in a test-driven environment. This book reveals how testing is a crucial capability in any iOS developer's toolset, and a minimum requirement in iOS interviews. A few years ago, tests on mobile platforms were not very popular. It wasn't a technical constraint, more a cultural one. But these days it's a crucial skill set, especially when projects become big and hard to maintain. This book shows you how to set up a testing target in XCode unit tests. You'll learn how to write unit tests properly and incorporate concepts like spies and mocks and code coverage.

Design and implement simulations using Apples Swift Playgrounds. Computer simulations are used to replicate the physical systems we see all around us. They help us solve problems by performing experiments that may otherwise be impossible in the real world. This book uses simulations to solve counter-intuitive logic puzzles, create procedural artworks, and build habitats for digital lifeforms. To help you create your own simulations using the Swift programming language, this book is filled with projects that you can easily follow along with. All you need is a Mac with the latest version of Xcode installed. All projects are written in Xcode's Playgrounds. This keeps the process simple. No need to setup an Apple account, or learn anything further about building apps. Simulations are used in many areas within computer science and yet, barely anyone is teaching them. Sure, the fundamentals are in algorithm design, but simulations are a step above that. Usually when writing an algorithm you have a specific outcome in mind. However, when you create a simulation, the system you are modelling can be far more unpredictable than sorting a list, or navigating a maze. Simulations in Swift 5 will guide you through all of this. What You'll Learn Simulate situations with advanced algorithms to solve advanced problems Incorporate real-world physics into simulated problems Predict biological and other systems behavior and the outcome of events based on presented factors Who This Book Is For Swift programmers interested in tackling fun projects in Swift involving advanced algorithms and factors
