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 3: Using Lists and Tables

There's a good chance that you have built a simple app before, or maybe you have tried but didn't quite succeed. If this is the case, you have likely used UITableView or UICollectionView, as both are core components of many iOS applications.

If an app shows a list of items, it was likely built using UITableView. This chapter will ensure that you are up to speed with the ins and outs of UITableView and UICollectionView. In addition to covering the basics, such as how we use the delegation pattern, you'll also learn how to access users' data – in this case, their contacts – which will be rendered in a UITableView and UICollectionView object.

We'll finish this chapter by taking a look at lists in SwiftUI, Apple's new UI framework announced back in 2019. We'll touch on the fundamental differences between what SwiftUI and UIKit have to offer.

The following topics will be covered in this chapter...
