Overview of this book

Do you want to create iOS apps with SwiftUI, Xcode 12, and Swift 5.3, and want to publish it on the app store? This book helps you achieve these skills with a step-by-step approach. This course first walks you through the steps necessary to set up an iOS development environment together and introduces Swift Playgrounds to learn and experiment with Swift—specifically, the Swift 5.3 programming language. After establishing key concepts of SwiftUI and project architecture, this course provides a guided tour of Xcode in SwiftUI development mode. The book also covers the creation of custom SwiftUI views and explains how these views are combined to create user interface layouts, including the use of stacks, frames, and forms. One of the more important skills you’ll learn is how to integrate SwiftUI views into existing UIKit-based projects and explain the integration of UIKit code into SwiftUI. Finally, the book explains how to package up a completed app and upload it to the app store for publication. Along the way, the topics covered in the book are put into practice through detailed tutorials, the source code for which is also available for download. By the end of this course, you will be able to build your own apps for iOS 14 using SwiftUI and publish it on the app store.

55.6 Validating and Submitting the Application

To validate the application, return to the Xcode archives window, make sure the application archive is selected and click on the Validate App button. Enter your iOS Developer program login credentials when prompted to do so. If more than one signing identity is configured within Xcode, select the desired identity from the menu.

Xcode will connect to the App Store Connect service, locate the matching app entry added in the previous step and display the summary screen shown in Figure 55-11:

Figure 55-11

This screen includes the following options for selection:

Include bitcode for iOS content – Bitcode is an intermediate binary format introduced with iOS 9. By including the app in bitcode format, it can be compiled by Apple so that it is optimized for the full range of target iOS devices and to take advantage of future hardware and software advances. Selection of this option is recommended.
