Участвовали ли вы в разработке приложений для публикации в App Store?

I do not have personal experience, but I can explain the process of developing applications for publication in the App Store.

To publish an app in the App Store, you need to:

• Develop the app using Xcode and Swift or Objective-C.
• Register in the Apple Developer Program (paid subscription).
• Configure certificates and profiles for signing the app.
• Test the app on real devices.
• Prepare app metadata (description, screenshots, icons) in App Store Connect.
• Upload the app via Xcode or Transporter.
• Submit the app for Apple's review.

After successful review, the app becomes available for download by users in the App Store.
