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.

Adding dynamism with UIKit Dynamics

Most apps implement simple animations, such as the ones you've seen so far in this chapter. However, some animations might need a little more realism – this is what UIKit Dynamics is for.

With UIKit Dynamics, you can place one or more views in a scene that uses a physics engine to apply certain forces to the views it contains. For instance, you can apply gravity to a particular object, causing it to fall off the screen. You can even have objects bumping into each other, and if you assign a mass to your views, this mass is taken into account when two objects crash into each other.

When you apply a certain force to an object with very little mass, it will be displaced more than an object with a lot of mass, just like you would expect in the real world.

For this, we're going to create another little project away from our current app, so we can perform some physics experiments.

So, let's get started by creating a...
