Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52648
This creates a `debugOptimized` build type for React Native Android, meaning that we can run C++ optimization on the debug build, while still having the debugger enabled. This is aimed at improving the developer experience for folks developing on low-end devices or emulators.
Users that intend to debug can still use the `debug` variant where the full debug symbols are shipped.

This is the output of the 3 generated .aar. The size difference is a proof that we're correctly stripping out the C++ debug symbols:

Summary:
When running a project in a path that contains any spaces, the scripts have several escape patterns that don't handle this path correctly. For example, `"/absolute/path/with spaces"` may be rendered as `/absolute/path/with spaces` and this shows as an output error such as `No such file or directory /absolute/path/with`
This was likely a longstanding issue, but is unexpected for some beginners that first try out React Native. While it's not recommended to create a path like this, it's certainly not hard to make this mistake.
## Changelog:
[IOS] [FIXED] - fix scripts for paths containing whitespaces
Pull Request resolved: https://github.com/facebook/react-native/pull/53194
Test Plan: tested locally; create a React Native or Expo project in a folder containing a space (e.g. `/my/path/with spaces/new-app` and build the project. With changes applied, the build should succeed. (There's related failures in `expo/expo` that need fixing too)

Summary:
Symbol files wasn't copied correctly when building - as with bundles we did overwrite the files and ended up with only the last symbol file.
This commit fixes this by mapping the framework build folder architecture type to the xcframework slices creating the correct file structure under the Symbols folder.
- Each slice gets a folder with the architecture name under Symbols containing the dSym folder for that slice
- Refactored getting correct architecture folder into a separate function.
- Refactored target folder lookup in copyBundles
- Removed unused async modifier on function
## Changelog:
[IOS] [FIXED] - Fixed how we copy and build the Symbols folder when precompiling ReactNativeDependencies

Summary:
When building the xcframeworks on iOS we're including the file `jsi/jsi.cpp` in the Swift Package. This file is also included in Hermes and React Native should use the hermes version of these symbols. This is even described (but overlooked) in the React-jsi podspec file.
This causes the error seen in the bug addressed by this commit.
The fix is to exclude the `jsi/jsi.cpp` file from the jsi target in our swift package.

Summary:
When copying bundle files from the platform folders in the .build output, the script had a bug where all bundles were copied - meaning that only the last one would be in the resulting xcframework output.
This caused an issue when we tried to publish an app built with precompiled binaries to AppStore where the field `CFBundleSupportedPlatforms` was wrong and caused the submission to be rejected. This was caused by the script copying the wrong bundle file into the final xcframework outputs.
This issue is described here:
https://github.com/react-native-community/discussions-and-proposals/discussions/923#discussioncomment-14089245
This commit fixes the above error by using the iOS 15 `vtool` to show the actual platform for a given framework and then making sure we don't copy bundles in the wrong way.
Testing this on my local machine for iOS/iOS-simulator/MacOS/catalyst yields the following results (before/after this fix):

Summary:
After fixing an isssue with ReactnativeDependencies and how it built symbols (https://github.com/facebook/react-native/issues/53353) this commit will align the output of the Symbols folder for the two frameworks.
Previously we had an output in the Symbols folder that looked like this (from a local build on my machine)
- catalyst
- iphone
- iphonesimulator
After this we now have the more correct arcitecture names on these folders:
- ios-arm64
- ios-arm64_x86_64-simulator
- ios-arm64_x86_64-maccatalyst
This is in line with how the ReactNativeDependencies Symbol folder is set up.

Summary:
When running `RCT_USE_PREBUILT_RNCORE=1 RCT_USE_RN_DEP=1 pod install` I'm getting an error: `cp: framework/packages/react-native/..: File exists`
This is not seen consistently by everyone but I've seen in reported one more time at Expo. Could be related to running MacOS 26.
Somehow, apparently, the `..` is being treated as a literal directory name and cp is trying to create a directory named `..` inside `framework/packages/react-native/` which is not what we want. Using `/.` avoids that.
---
What also seemed to work(around) was to change `mkdir -p framework/packages/react-native` to `mkdir -p framework/packages/` and then `cp` can create the `framework/packages/react-native/..` folder. But this is definitely more confusing.

Side-note: It's pulled in via `react-native/community-cli-plugin` which is a direct dependency of `react-native` for the `scripts/bundle.js` script. While, for expo, we'd love to find a way to make this an optional dependency (to avoid excessive deps that `expo` replaces otherwise), for now, it's a direct dependency.
The problem here is that this isn't optional, which means:
- with auto-installing peer dependencies it is directly fulfilled (while `react-native-community/cli` is already marked as optional and skipped)
- with legacy/non-auto peer-dependencies it is flagged as missing, but in an Expo project it wouldn't make sense to install directly
This causes a **package manager regression in the form of either a peer dependency warning**, that shouldn't be fulfilled in an Expo project, or (in the best case scenario) pulls in dependencies [that a user does not need](https://npmgraph.js.org/?q=%40react-native%2Fmetro-config#zoom=w&select=exact%3A%40react-native%2Fmetro-config%400.81.0).
An error message is already in place to inform the user of this being missing when it's not installed, so marking it as optional seems appropriate.

* [ios][precompile] Add use_frameworks resolve method
To be able to handle cocoapods USE_FRAMEWORKS with both dynamic/static linkage and precompiled we needed a common way to resolve this.
The issue was that when using precompiled and USE_FRAMEWORKS our precompiled framework caused the resulting Pods project to only include header files - hence there where no need to change the header_mappings_dir which a lot of the podspecs did.
A method was added that handles this in a common way.
* [ios][precompile] added resolve_use_frameworks to podspecs
Replaced logic for resolving header mappings and module name using the new method `resolve_use_frameworks` in all podspecs.
Also added `React-oscompat` dependency on `React-jsiinspector_modern` which failed when linkage was "dynamic".
* [ios][precompile] added explicit handling of ReactCoden
When using precompiled and building with frameworks (USE_FRAMEWORKS) we need to explicitly add the correct path to ReactCodegen when calling `create_header_search_path_for_frameworks` to ensure libraries can access their codegen files.
This commit adds an explicit check to make sure we add the correct path when using frameworks and the pod is ReactCodegen.
Added includes in the NativeCXXModuleExample.cpp file to test this.
* Update packages/react-native/scripts/cocoapods/utils.rb

Summary:
Hello, I work on [Radon IDE](ide.swmansion.com) I encountered an issue while adding support for react native 81, this PR solves it:
In https://github.com/facebook/react-native/issues/51023 EvanBacon removed `displayName` filed from `View` component adding the following comment:
>Remove displayName in favor of component name. I'm not 100% sure this is a full fallback but it is valid according to react/display-name eslint rule—https://github.com/jsx-eslint/eslint-plugin-react/blob/master/docs/rules/display-name.md
Unfortunately the Fabric renderer uses the `displayName` property to generate the name of the component for the inspector functionality and in absence of it generates a name that might be confusing to the end user:

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52660
The documentation for those methods mention that users should override them to
provide their own implementation.
However those vals are not `open` so users cannot really override them.
This fixes it.
See more context on https://github.com/facebook/react-native/pull/48800#issuecomment-3082665024
So this was practically a breaking change, that I'm attempting to mitigate.

* Do not setup-node twice in test_js (#52737)
Summary:
I've noticed that test_js (20) and test_js (24) are actually running on Node 22.
That's because the `yarn-install` action is invoking setup-node again with the default value (22).
This changes it. Also I'm cleaning up the workflows so that every `yarn-install` invocation is happening just after the `setup-node` invocation.

* Fix incorrect locking and attempts check in ShadowTree experiment (#52681)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52681
Changelog: [internal]
In the original change I made in D78418504 / https://github.com/facebook/react-native/pull/52645 I made 2 mistakes:
1. Used a lock that would try to re-lock on itself without it being recursive (which would cause a deadlock). I didn't see that because when testing I didn't hit the case where we'd exhaust the options.
2. The `attemps` variable wasn't incremented, so we never left the loop in case of exhaustion.
This propagates a flag to `tryCommit` to indicate we've already locked on the commitMutex_ so we don't need to lock again in that case and increases the counter, fixing the issue.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52625
Changes `react-native/babel-preset` so that by default, `hermes-parser` is configured with `reactRuntimeTarget: "19"`. This changes the compiled output of Component Syntax to not use `forwardRef` when a `ref` prop is present.
Additionally, this adds a new preset option property, `hermesParserOptions`. This object allows users of `react-native/babel-preset` to supply overrides for any `hermes-parser` options.
Changelog:
[General][Changed] - Configures `react-native/babel-preset` to target React 19 by default, meaning Component Syntax will not compile to `forwardRef` calls when a `ref` prop is present.
[General][Added] - Added support to `react-native/babel-preset` for a `hermesParserOptions` option, that expects an object that enables overriding `hermes-parser` options.
