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 vibrancy to animations

A lot of animations on iOS look bouncy and feel natural. For instance, when an object starts moving in the real world, it rarely does so smoothly. Often, something moves because something else applied an initial force to it, causing it to have a certain momentum. Spring animations help you to apply this sort of real-world momentum to your animations.

Spring animations are usually configured with an initial speed. This speed is the momentum an object should have when it begins moving. All spring animations require damping to be set on them.

The value of this property specifies how much an object can overflow its target value. A smaller damping value will make your animation feel bouncier because it will float around its end value more drastically.

The easiest way to explore spring animations is by slightly refactoring the animation you just created for the drawer.

Instead of using an easeOut animation when a user taps the Toggle Drawer button...
