I'm also getting same issue

[ajtosh77]

Same here... Any luck with a workaround or better luck with a different RN Unity package?

Hi all,

The [UnityFramework setRNUnityProxy:] selector is implemented in this file:

• https://github.com/fusetools/react-native-unity2/blob/main/unity/Assets/RNUnity/RNUProxy.m

The file is used to implement message passing between Unity and the React Native app.

All files in the RNUnity directory is supposed to be added to your Unity project when using react-native-unity2:

• https://github.com/fusetools/react-native-unity2/tree/main/unity/Assets/RNUnity

I copy the RNUnity folder to my Unity project assets and create build, it's working fine ):

Issue Resolved: Unity Integration with react-native-unity2 on iOS

I faced an issue while integrating Unity with React Native using the react-native-unity2 package. Below are the steps I followed to resolve it:

Issue Encountered:

After adding the RNUnity folder to my Unity project, I encountered the following error while building:

Assets/RNUnity/RNPromise.cs(3,7): error CS0246: The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?)

Steps to Resolve:

1. Add the RNUnity Directory to Unity Project:

   • Downloaded the react-native-unity2 repository from GitHub.
   • Located the RNUnity folder within the repository.
   • Copied the RNUnity folder into the Assets directory of my Unity project.

2. Fix Newtonsoft.Json Missing Error:

   • Opened Unity and navigated to Window > Package Manager.
   • Clicked the + button and selected "Add package by name...".
   • Entered com.unity.nuget.newtonsoft-json as the package name and clicked "Add".
   • After adding the package, cleaned and rebuilt the Unity project.

3. Followed Official Documentation for Further Setup:

   • [Getting Started Guide](https://github.com/fusetools/react-native-unity2/blob/main/docs/getting-started.md)
   • [Unity Artifacts Setup](https://github.com/fusetools/react-native-unity2/blob/main/docs/unity-artifacts.md)

Outcome:

After performing the above steps, both the integration and build processes completed successfully without errors.

Hope this helps anyone facing similar issues! 🚀
