Description

XCode 26 set the SWIFT_ENABLE_EXPLICIT_MODULES build setting to YES by default. This breaks building with precompiled binaries.

This commit fixes this by adding a step when using the precompiled binaries to explicitly set the SWIFT_ENABLE_EXPLICIT_MODULES flag to NO.

Thank you for opening a new pick-request for React Native.
Those are the criterias we follow when accepting/rejecting a pick request (source).

If your pick does not satisfy the criteria below, please close it as it will not be considered.

✅ Which pick requests we accept

1. ✅ Fixes for regressions to core APIs. Examples:
   • A core component is behaving differently between version 0.X and 0.X-1
   • The TurboModule.getEnforcing function is throwing an assertion error which is not expected.
2. ✅ Fixes to bugs in the core React Native’s experience. Examples:
   • Breakpoints in React Native DevTools not working correctly in the debugger
   • Fast Refresh not working as expected
   • Metro bundler not starting properly or ignoring the configuration file
   • Buttons that are not clickable
3. ✅ Fixes to APIs used by 3P libraries and Out-of-tree platforms. Examples:
   • An API that is used by react-native-macos is not behaving as expected or regressing
4. ✅ Bump of patch version of dependencies. Example:
   • Bump Gradle from 8.11.0 to 8.11.1
5. ✅ Fixes for Low/High Security Vulnerability. Example:
   • Bump Gradle from 8.11.0 to 8.12.0 if there is a security vulnerability in 8.11 and there is no version 8.11.x which would contain the same fix.
6. ✅ Fixes and reverts of accidental breaking changes. Example:
   • Reverting or fix-forwarding a migration to Kotlin of a file (say ReactRootView.java ) if that is causing a breaking change for the whole React Native ecosystem.
7. ✅ Performance improvements picks. Examples:
   • Fixing unnecessary rendering on FlatList.
8. ✅ Any pick if the release is still in RC0 (after RC1 the previous listed criteria applies)

❌ Which pick requests we don’t accept

9. ❌ Any pick that will introduce a breaking change after RC1. Example:
   • A bugfix that contains a refactoring, resulting in changes to the public API of a class
10. ❌ Any pick that introduces a new feature after RC1. Example:
    • A commit that introduces a new API or a specific feature for a component.
11. ❌ Bump of major/minor version of dependencies. Example:
    • Bump Gradle from 8.11.0 to 8.12.0
    • Bump Gradle from 8.11.0 to 9.0.0
12. ❌Bump of a dependency to a non stable/alpha/beta version. Example:
    • Bump Gradle from 8.11.0 to 8.11.1-beta.1
13. ❌Any pick that introduces changes to the testing infrastructure of React Native after RC1. Examples:
    • Changes to the GitHub Actions workflows to optimize it, even if they’re on main.
    • Changes to the logic used to publish packages to NPM or Maven Central
14. ❌ Pick composed by various commits that has several merge conflicts
    • If your pick is too complicated to apply on the release branch, we’re going to reject it.
15. ❌ Any other non-critical improvement that landed on main.
    • In general those will ship in the following version unless they fit in one of the criteria above
16. ❌ Any other pick which is considered “small enough” to make it into a release.
    • If your pick is a one liner but is a ‘nice to have’, we won’t be picking it, as it has the risk of destabilizing the release and further delaying the release.

ℹ️ What makes for a good pick

In order for your pick to be considered, please do the following:

• ℹ️ Have a pick that contains only one commit from main, or only one PR against the release branch.
• ℹ️ Have a clear explanation of why your pick should be considered, ideally referencing one of the criteria above.
• ℹ️ Target only one minor version of React Native (e.g. [0.76]). If you want your pick to be applied to more versions, please open different picks.
