Saad Najmi 73664f576a feat(iOS): Implement cursor style prop (#43078)
Summary:
Implement the cursor style prop for iOS (and consequently, visionOS), as described in this RFC: https://github.com/react-native-community/discussions-and-proposals/pull/750

See related PR in React Native macOS, where we target macOS and visionOS (not running in iPad compatibility mode) with the same change: https://github.com/microsoft/react-native-macos/pull/2080

Docs update: https://github.com/facebook/react-native-website/pull/4033

## Changelog:

[IOS] [ADDED] - Implement cursor style prop

Pull Request resolved: https://github.com/facebook/react-native/pull/43078

Test Plan:
See the added example page, running on iOS with the new architecture enabled. This also runs the same on the old architecture.

See the example page running on all three apple platforms. The JS is slightly different because:
1. The "macOS Cursors" example is not part of this PR but the one in React Native macOS.
2. This PR (and exapmple) has went though a bunch of iterations and It got hard taking videos of every change 😅

## Notes

- React Native macOS added the cursor prop to View with https://github.com/microsoft/react-native-macos/pull/760 and Text with https://github.com/microsoft/react-native-macos/pull/1469 . Much of the implementation comes from there.

- Due to an Apple bug, as of iOS 17.4 Beta 4, the shape of the iOS cursor hover effect doesn't render in the correct bounds (but it does on visionOS). I've worked around it with an ifdef. The result is that the hover effect will work on iOS and visionOS, but not iPad apps running in compatibility mode on visionOS.

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 13.4 and Android 6.0 (API 23) 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 this discussion repo.
