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.

Understanding ARKit

In this section, we will learn about Augmented Reality (AR) and ARKit. Augmented Reality (AR) is a topic that has captured the interest of app developers and designers for a long time now. Implementing an excellent AR experience had not been easy though, and many applications haven't lived up to the hype. Small details such as lighting and detecting walls, floors, and other objects have always been extremely complicated to implement and getting these details wrong has a negative impact on the quality of an AR experience.

Augmented reality apps usually have at least some of the following features:

  • They show a camera view.
  • Content is shown as an overlay in the camera view.
  • Content responds appropriately to the device's movement.
  • Content is attached to a specific location in the world.

Even though this list of features is simple, they aren't all trivial to implement. An AR experience relies heavily on reading the motion...
