Overview of this book

If you're looking to work and experiment with powerful iOS 14 features such as widgets and App Clips to create your own apps, this iOS programming guide is for you. The book offers a comprehensive introduction for experienced programmers who are new to iOS, taking you through the entire process of learning the Swift language, writing your own apps, and publishing them on the App Store. Fully updated to cover the new iOS 14 features, along with Xcode 12 and Swift 5.3, this fifth edition of iOS 14 Programming for Beginners starts with an introduction to the Swift programming language and shows you how to accomplish common programming tasks with it. You'll then start building the user interface (UI) of a complete real-world app using the storyboards feature in the latest version of Xcode and implement the code for views, view controllers, data managers, and other aspects of mobile apps. The book will also help you apply iOS 14 features to existing apps and introduce you to SwiftUI, a new way to build apps for all Apple devices. Finally, you’ll set up testers for your app and understand what you need to do to publish your app on the App Store. By the end of this book, you'll not only be well versed in writing and publishing applications, but you’ll also be able to apply your iOS development skills to enhance existing apps.

Summary

In this chapter, you modified the cells in the Explore, Restaurant List, and Locations screens to match the design shown in the app tour. For the Explore screen, you added labels and a view to the collection view section header, configured the button with a custom image, and modified the exploreCell collection view cell by adding an image view and a label to it, as well as the required constraints. For the Restaurant List screen, you modified the restaurantCell collection view cell by adding labels, buttons, and an image view to it, configured it to show a default image, and added the necessary constraints. For the Locations screen, you configured a prototype cell for the table view and set the identifier for the table view cells to locationCell.

You now have experience of how to use the Interface Builder editor to add and configure multiple UI elements, set their sizes and positions using the Size inspector, and apply the necessary constraints using the Add New Constraints...
