IPA file creation for IOS mobile app

We have a project in React Native with a set set of functionalities. We have created the aab file for android app. We need to generate IPA file for IOS app and remove any package or any other configuration issues. After creating the IPA file, whatever configuration settings and changes were required to generate the IPA file needs to be sent to us as a report and help us in configuration settings so that we are able to generate the IPA file on our system for further development.
