Mastering iOS 14 Programming - Fourth Edition

By: Mario Eguiluz Alebicto, Chris Barker, Donny Wals

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.

Chapter 12: Improving Apps with Location Services

All iOS devices come with a huge variety of chips and sensors that can be used to enhance the user experience. Augmented reality applications make heavy use of sensors such as the gyroscope, accelerometer, and camera. These sensors are great if you want to grab a picture or want to know how a device is moving. Other apps require different data, such as the user's GPS location at a given time. In this chapter, you will learn how to use the Core Location framework to do just that.

Core Location is a framework that allows developers to gain access to a user's current location, but it also allows developers to track whether a user has entered or exited a specific area, or even to monitor a user's location over time. A proper implementation of Core Location can be the core of many great features in your app, but a lousy implementation could drain a user's battery in no time.
