Chapter 1: Getting Familiar with Xcode

Welcome to iOS 14 Programming for Beginners. I hope you will find this a useful introduction to writing and publishing iOS 14 apps on the App Store.

In this chapter, you'll learn how to download and install Xcode on your Mac. You'll familiarize yourself with the different parts of the Xcode user interface, and you'll create your first iOS app and run it in the iOS simulator. You will then learn how to connect an iOS device to Xcode via USB so that you can run the app on it, how to add an Apple ID to Xcode so that the necessary digital certificates can be created and installed on your device, and how to trust the certificate on your device. Finally, you will learn how to connect to your device over Wi-Fi, so you no longer need to plug and unplug your device every time you want to run an app.

By the end of this chapter, you will know how to create and run apps on the iOS simulator or a device, which you will need to do when you build your own apps.

The following topics will be covered:

  • Downloading and installing Xcode from the App Store
  • Understanding the Xcode user interface
  • Running the app in the iOS simulator
  • Using an iOS device for development
