Turbo module generated files are not registered with the ios app extension targets

[Nehal-Zeller]

Description

Objective: implement an ios extension (share extension) which opens a react native view and calls extension completeRequest from the RN view in new architecture with the help of turbo module NativeShareUIModule.

Issue I'm encountering is: Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'NativeShareUIModule' could not be found. Verify that a module by this name is registered in the native binary., js engine: hermes

Main app targets compile successfully and also I can see specs

`@implementation NativeShareUIModuleSpecBase

- (void)setEventEmitterCallback:(EventEmitterCallbackWrapper *)eventEmitterCallbackWrapper
{
  _eventEmitterCallback = std::move(eventEmitterCallbackWrapper->_eventEmitterCallback);
}
@end
namespace facebook::react {
  
    static facebook::jsi::Value __hostFunction_NativeShareUIModuleSpecJSI_completeRequest(facebook::jsi::Runtime& rt, TurboModule &turboModule, const facebook::jsi::Value* args, size_t count) {
      return static_cast<ObjCTurboModule&>(turboModule).invokeObjCMethod(rt, PromiseKind, "completeRequest", @selector(completeRequest:resolve:reject:), args, count);
    }

  NativeShareUIModuleSpecJSI::NativeShareUIModuleSpecJSI(const ObjCTurboModule::InitParams &params)
    : ObjCTurboModule(params) {
      
        methodMap_["completeRequest"] = MethodMetadata {1, __hostFunction_NativeShareUIModuleSpecJSI_completeRequest};
  }
} // namespace facebook::react

I've shared a zip files of what I'm doing
in podfile, I've added a post-install to link codegen generated files with my share extension but that's not helping

`post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings["ONLY_ACTIVE_ARCH"] = "NO"
if target.name != "Sentry"
config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'NO'
end
end
end

# https://github.com/facebook/react-native/blob/main/packages/react-native/scripts/react_native_pods.rb#L197-L202
react_native_post_install(
  installer,
  config[:reactNativePath],
  :mac_catalyst_enabled => false,
  # :ccache_enabled => true
)
# Link Codegen-generated TurboModules to Share Extension
  share_ext_target = installer.pods_project.targets.find { |t| t.name == 'ShareExt' }
  if share_ext_target
    # Adjust path based on your structure
    codegen_dir = File.join(__dir__, './build/generated/ios')
    extensions = ['h', 'm', 'mm', 'cpp']

    Dir.glob("#{codegen_dir}/**/*.{#{extensions.join(',')}}").each do |file_path|
      relative_path = Pathname.new(file_path).relative_path_from(Pathname.new(installer.pods_project.path.dirname)).to_s
      file_ref = installer.pods_project.new_file(relative_path)

      # Avoid duplication
      unless share_ext_target.source_build_phase.files_references.include?(file_ref)
        share_ext_target.add_file_references([file_ref])
      end
    end
  end

end`

`function IssuerUIExtension() {
  return (
    <View style={{ flex: 1, backgroundColor: 'red' }}>
      <Text
        style={{ color: 'white', textAlign: 'center', marginTop: 20 }}
        onPress={() => NativeShareUIModule.completeRequest('true')}
      >
        Issuer UI Extension Placeholder
      </Text>
    </View>
  );
}
export default IssuerUIExtension;`

package.json codegen config:

"codegenConfig": {
    "name": "ZappSpec",
    "type": "modules",

  }

@Nehal-Zeller extensions are a use case we never worked on actively, nor that we supported explicitly. I think you are sailing in uncharted waters.
