Summary:
{emoji:26a0} This is a follow up to https://github.com/facebook/react-native/issues/25425 -- which isn't merged yet… See https://github.com/facebook/react-native/pull/25919/files/2a286257a6553a80a34e2b1f1ad94fc7bae36ea3..125aedbedc234c65c8d1b2133b79e926ad6cf145 for actual diff
Currently, StatusBar native module manages the status bar on iOS globally, using `UIApplication.` APIs. This is bad because:
- those APIs have been deprecated for 4 years
- Apple really, really wants you to have an explicitly defined view controller, and control the status bar there
- it [breaks external native components](https://github.com/facebook/react-native/issues/25181#issuecomment-506792819)
- it's [not compatible with iPadOS 13 multi window support](https://github.com/facebook/react-native/issues/25181#issuecomment-506690818)
for those reasons I we should transition towards view controller-based status bar management.
With that, there is a need to introduce a default React Native root view controller, so I added `RCTRootViewController`. Using it is completely opt-in and there is no breaking change here. However I believe this should be a part of the template for new RN iOS apps.
Additionally, I added `RCTRootViewControllerProtocol` with hooks needed for RCTStatusBarManager to control the status bar. This means apps that want to have total control over their view controller can still opt in to react native VC-based status bar by conforming their root view controller to this protocol.
## Changelog
[iOS] [Added] - Added `RCTRootViewController` and `RCTRootViewControllerProtocol`
[iOS] [Fixed] - `UIViewControllerBasedStatusBarAppearance=YES` no longer triggers an error as long as you use `RCTRootViewController`
[iOS] [Fixed] - Status bar style is now correctly changed in multi-window iPadOS 13 apps if you use `RCTRootViewController` and set `UIViewControllerBasedStatusBarAppearance=YES`
Pull Request resolved: https://github.com/facebook/react-native/pull/25919
Test Plan: - Open RNTester → StatusBar → and check that no features broke

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 10.0 and Android 4.1 (API 16) 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 repo, @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 the React Native Community, @react-native-community/react-native-releases.
