I have finished my React Native application and the iOS version works properly on a simulator when I run: npx react-native run-ios
I then the follow the instructions on the documentation to create a release:
https://reactnative.dev/docs/running-on-device#3-build-app-for-release
I then looked for the .app file created by running:
npx react-native run-ios --configuration Release
I then created a folder called Payload and put the .app file inside and zipped it up. After zipping the folder I changed the .zip extension to .ipa
When I submit the app to the Appstore I get the following errors:
ERROR ITMS-90174: "Missing Provisioning Profile - Apps must contain a provisioning profile in a file named embedded.mobileprovision."
How to add Provisioning Profile to iOS release build in React Native?
You have to purchase the app store account by paying $100 for an annual subscription then generate a .certSigningRequest file from your keychain and upload that file to the app store, Setup provisioning in your app store account for development or production environment which you want and download this profile from the app store.
Add this newly created provisioning profile to your Xcode project and then archives your project, It will create a .ipa file, either upload your archive with Xcode or export .ipa and upload manually to test flight or anywhere you want.
Here is a tutorial to set up your profile in Xcode.
