I just followed the instructions from your official documentation.
Configure release scheme on xcode To configure your app to be built using the Release scheme, go to Product → Scheme → Edit Scheme. Select the Run tab in the sidebar, then set the Build Configuration dropdown to Release.

For 0.72, you should re-install your pods with
To remove Flipper from the Release build. We are aware that Flipper can’t be built in Release mode, but we are deprecating Flipper in 0.73 and it will be removed in 0.74.
We are working on a replacement for Flipper. In 0.73, it will still be experimental, hence why Flipper is only deprecated in 0.73. In 0.74 we will provide a debugger that should replace Flipper.
The only thing that worked to me was replace all the part from “post_install” on Podfile to the code below.
use_flipper!()
post_install do |installer| react_native_post_install(installer) installer.pods_project.build_configurations.each do |config| config.build_settings[“EXCLUDED_ARCHS[sdk=iphonesimulator*]”] = “arm64” end end
After that. Run the following commands in terminal on iOS folder.
pod deintegrate && pod install
Now clean build cache on Xcode and run the project.
Shortcut: CMD + SHIFT + K
I moved
react-native-flipperinpackage.jsonfromdependenciestodevDependencies.I managed to
buildthe application andArchiveit successfully 🥳I used the full command
PRODUCTION=1 NO_FLIPPER=1 bundle exec pod installFlipper is going to be deprecated in React Native 0.73 and removed in React Native 0.74, so we will not incur in these problems anymore soon.
Unfortunately it produced
