NativeModules are empty

[Sebulec]

Description

When creating new native library for application, when library is attached to the react native mobile application in iOS, the NativeModules are empty ({})

React Native version:

System: OS: macOS 10.15.5 CPU: (6) x64 Intel(R) Core(TM) i5-8500B CPU @ 3.00GHz Memory: 30.54 MB / 8.00 GB Shell: 5.7.1 - /bin/zsh Binaries: Node: 12.14.1 - /usr/local/bin/node Yarn: 1.21.1 - /usr/local/bin/yarn npm: 6.14.2 - /usr/local/bin/npm SDKs: iOS SDK: Platforms: iOS 12.4, macOS 10.14, tvOS 12.4, watchOS 5.3 IDEs: Android Studio: 3.6 AI-192.7142.36.36.6308749 Xcode: 10.3/10G8 - /usr/bin/xcodebuild npmPackages: react: 16.11.0 => 16.11.0 react-native: 0.62.2 => 0.62.2 npmGlobalPackages: create-react-native-app: 3.4.0 react-native-create-library: 3.1.2 react-native: 0.61.4

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Create new RN application using create-react-native-app my-project
2. Create new native library using react-native-create-library -—platforms ios,android my-library
3. Configure XCode .xcworkspace project, link React library to the project, to let project see React binaries.
4. In my-project app add

import { Button, NativeModules } from 'react-native';
const App: () => React$Node = () => {
  return (
    <>
      <StatusBar barStyle="dark-content" />
      <SafeAreaView>
        <Button title="Press" onPress={() => onPress()}></Button>
      </SafeAreaView>
    </>
  );

  function onPress() {
    console.log(NativeModules);
  }
};

Expected Results

It doesn't matter if it's XCode 11 or XCode 10, the NativeModules is empty. When printing NativeModules.MyLibrary it's null.

Does the behavior vary with remote JS debugging being enabled and disabled?

[Sebulec]

@chrisbobbe Thanks for response, when JS is enabled, I can see some libraries but there is no MyLibrary.

Anybody working on this issue or has anyone found a fix? I am currently experiencing the issue too.

expo: "~48.0.4" react: "18.2.0" react-native: "0.71.3"

Gradle version is 7.5.1. XCode version is 1.74.3 (Universal)

Can't share the project as it is private but I was working from this tutorial..

[silvabacc]

Yes, I am getting the same issue on the same version of react-native 0.71.3. I can see a duplicate issue here. I followed the same guide @macro6461

[lumairink]

Same happening on version 0.71.13

[Gowthamr221]

Happening to me i created a native component following the guide from react native docs the native component returns null on react-native version 0.73.1. i found old discussion about this issue Native Modules #96 but no proper resolution yet.
