Run a React Native iOS release build from terminal
I did a PR to the React Native project to allow this feature. The PR can be check here: https://github.com/facebook/react-native/commit/ca7cbdee858e84c4a74a2d9c7be151f5cfdcfbfe
So, in the future, to run a release build from terminal you just only need to type the following command:
npx react-native run-ios --configuration Release
If you want run your project on a real device use
npx react-native run-ios --configuration Release --device "Your Device Name"
As far as I know, react native doesn't come with something like that out-of-the-box.
But because your react-native app is also a plain Objective-C app with react-native on the inside, you can re-use existing tools to perform the build/packaging for you.
Check the following article for example on how to automate your build using fastlane.
The react-native script that handles the bundling is here:
and it basically does this:
node "./node_modules/react-native/cli.js" bundle --entry-file "index.js" --platform ios --dev false --reset-cache --bundle-output "./app.app/main.jsbundle" --assets-dest "./app.app"
where bundle-output and asset-dest would normally point to your xcode build output. For example:
