Summary: See https://github.com/facebook/react-native/issues/51212 - children aren't updated correctly in an old arch native view using the interop layer under Fabric. This is caused by the mountChildComponentView method not updating the view, only adding the new view to a list that will be used on the next update to mount the child. This commit fixes this by adding the same pattern as in unmountChildComponentView where children are inserted directly if the underlying paperview is available in the adapter - otherwise it uses the mounting list as before. #Closes 51212 bypass-github-export-checks ## Changelog: [IOS] [FIXED] - fixed adding child views to a native view using the interop layer Pull Request resolved: https://github.com/facebook/react-native/pull/51213 Test Plan: **Previous output**: <image src="https://github.com/user-attachments/assets/472b95e7-0921-46c9-be6a-f31759c0cd26" width="200px" /> **After fix**: <image src="https://github.com/user-attachments/assets/554387cd-c264-483e-9c52-d9cd40b42601" width="200px" /> Reviewed By: sammy-SC Differential Revision: D74471278 Pulled By: cipolleschi fbshipit-source-id: 798f9e7be389359bd6e3aa1b6a6e9fb799fcb369

React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 15.1 and Android 7.0 (API 24) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repository, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in this discussion repo.
