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

Produce high-quality, cross-platform apps with user experiences almost identical to pure native apps.

Build highly modular software in macOS that interacts deeply and intuitively with other programs. This book explores all techniques available for Inter-process communications (IPC) from high level macOS layers to deep kernel options while applying theoretical concepts into practical implementations on real world scenarios. You'll see how IPC techniques are used for exchanging data and messages among multiple threads in one or more processes, which may be running on one or more computers connected by a network or running locally. IPC methods can be divided into methods for message passing, synchronization, shared memory, and remote procedure calls (RPC). A poorly conceived IPC can even expose an entire network to over-the-network attacks. Despite the risks, processes and applications absolutely need to communicate with each other across your system and the network. You'll see how these communications facilitate information sharing, computational speedup, modularity, convenience, and privilege separation. In macOS, a program has a number of ways to communicate with other programs. These mechanisms for IPC often exist in different layers of the system. You'll examine how each has its own specific purposes, limitations, and intended scenarios. Some are more suitable than others for code written at a certain level of the system. For example, a kernel extension would not make use of Apple events. Additionally, the book reveals that different users have different rights when it comes to accessing files, changing system wide settings, and so on, depending on whether they are admin users or ordinary users. Running code with root or administrative privileges can intensify the dangers posed by security vulnerabilities. You'll learn that to elevate privileges safely, it is mandatory for the application to perform the task through a secure Helper process. What You'll Learn Expand the capabilities of your programs by sharing data within multiple applications Understand and dig deep into the world of Helper tools to create apps that need user privilege elevation Enhance the modularity of a system by allowing your applications to interact and share data with a website Who This Book Is For Software engineers and architects designing and developing secure applications for macOS and iOS who have hands-on knowledge of Swift with XCode.

Work with Apple Maps, Google Maps, and Mapbox in iOS with Swift programming. Guided by practical examples, this book covers all three map frameworks to ensure you properly select which one best suits your iOS app's needs in working with iOS location. You'll see how Apple's privacy settings apply to a user's location, and how to access that user's location from an application. Once you have access to the user's location, allow your app to display points of interest from Apple's database on the map inside the app, as well as to provide a search through that database by name. You can also incorporate turn by turn directions inside your own app to provide routes. Or trigger different functionality or notifications based on locational queues. With Build Location Apps on iOS with Swift, you'll even find out how to provide offline map support for hiking, camping, or other outdoors applications where cell phone service is weak. What You'll Learn Display points of interest within your own app Work with Apple's privacy settings so pertinent information comes through Trigger functionality based on geographic prompts Create your own custom map styles with Mapbox Studio and display them in the app Who This Book Is For Intermediate to advanced Swift programmers who would like to add location based services to their apps.
