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.

Building your first Mac Catalyst app

In this section, we are going to start working with a simple iPad to-do app, and we will transform it into a macOS app using two different techniques. The base app is very basic (you can't even add new to-do elements to it!) but it illustrates what kinds of errors, UI modifications, and methods you need to go through when going from iPad to Mac.

We will follow these steps:

  1. First, we will explore the iPad app itself to understand its essential elements and components.
  2. Then, we will use the first method to make it compatible with macOS: Scale Interface to Match iPad.
  3. Finally, we will use the new method, Optimize Interface for Mac. We will compare the results with the Scale Interface method to match the iPad method, so you will learn when to use one or another, depending on your app.

Let's start by exploring our iPad to-do app!
