Overview of this book

Mastering iOS 14 development isn’t a straightforward task, but this book can help you do just that. With the help of Swift 5.3, you’ll not only learn how to program for iOS 14 but also be able to write efficient, readable, and maintainable Swift code that reflects industry best practices. This updated fourth edition of the iOS 14 book will help you to build apps and get to grips with real-world app development flow. You’ll find detailed background information and practical examples that will help you get hands-on with using iOS 14's new features. The book also contains examples that highlight the language changes in Swift 5.3. As you advance through the chapters, you'll see how to apply Dark Mode to your app, understand lists and tables, and use animations effectively. You’ll then create your code using generics, protocols, and extensions and focus on using Core Data, before progressing to perform network calls and update your storage and UI with the help of sample projects. Toward the end, you'll make your apps smarter using machine learning, streamline the flow of your code with the Combine framework, and amaze users by using Vision framework and ARKit 4.0 features. By the end of this iOS development book, you’ll be able to build apps that harness advanced techniques and make the best use of iOS 14’s features.

Summary

In this chapter, you have learned several techniques to obtain and respond to a user's location. You have implemented a LocationHelper class that provided a simple interface for view controllers to use the location manager that is contained in the helper.

You learned that there are different ways, each with different levels of detail, that you can use to track a user's location. You saw that you can subscribe to continuous changes, which has a bad impact on battery life. You also learned about subscribing to visits and significant location changes. In addition to learning about tracking a user's location, you also learned about monitoring whether a user has entered or exited a certain area by implementing geofencing...
