The information you’ve read so far focused on how to create an app in Xcode. However, there are other things you must do to publish an app on the App Store.
To make a great app, you need to test it on actual devices throughout the development process, not just in Simulator. To run an app on iOS-based devices, you need to register the devices you want to test on, create certificates that authorize developers to sign an app, and create an app ID to identify the app.
After you test and refine your app, you need to submit it through iTunes Connect. Your app must be approved by App Store reviewers before it’s published.
