Summary: `install_modules_dependencies` is the helper every third-party New Architecture library calls from its own podspec, and `update_search_paths` covers the user project and the pod targets that don't go through it. Neither knew about `React-cxxstableapi`. React Native's public C++ headers are starting to include the shared guard header `<react/cxxstableapi/UmbrellaGuard.h>`. The include is unconditional, so a third-party pod that includes any guarded React Native header has to be able to resolve it. Today it can't: in the default static-library mode `$(PODS_ROOT)/Headers/Public/React-cxxstableapi` is missing from the search path, and under `use_frameworks!` the `React_cxxstableapi.framework/Headers` entry is missing. Declare the dependency and add the matching framework header search path in both places. Changelog: [iOS][Added] - Add a `React-cxxstableapi` dependency to third-party New Architecture pods so they can resolve React Native's C++ API guard headers Differential Revision: D110052811
Summary: React Native's public C++ headers are gaining guards from `react/cxxstableapi`. Those guards turn a direct include of a fine-grained header into an error for consumers that opt into the strict API by defining `RN_STRICT_API`. React Native's own sources keep including those fine-grained headers directly, so they have to be exempt — the guards recognise the exemption via `RN_BUILDING`. Mark every first-party pod as part of React Native's own build by defining `RN_BUILDING` for it, through a new `mark_as_react_native_build` helper called last in each spec block (it merges into `GCC_PREPROCESSOR_DEFINITIONS` as `pod_target_xcconfig` stands at call time, so a later assignment would drop it). Third-party pods deliberately do NOT get this: they compile their own code against the public API and must remain subject to the guards. For the same reason the definition goes into `pod_target_xcconfig`, which applies to the pod's own target, rather than `user_target_xcconfig`, which would leak it to the app. Not applied to `third-party-podspecs/`, `sdks/hermes-engine`, or the codegen podspec templates — those are third-party or app-side generated pods, and exempting them would be an enforcement hole rather than a no-op. This change is inert on its own: nothing behaves differently unless a consumer defines `RN_STRICT_API`. Changelog: [Internal] Differential Revision: D115051089
…rgets Summary: Companion to the CocoaPods change: does the same for the other three build systems, so every build has exactly one place that states "these targets are React Native's own". React Native's public C++ headers are gaining guards from `react/cxxstableapi`, which turn a direct include of a fine-grained header into an error for consumers that opt into the strict API by defining `RN_STRICT_API`. React Native's own sources keep including those headers directly, so they are exempted via `RN_BUILDING`. Unlike CocoaPods, these three build systems each have a single chokepoint: - CMake: one `add_compile_definitions(RN_BUILDING)` in the ReactAndroid JNI project, a directory property inherited by every `add_react_common_subdir` below it. It is declared *after* the third-party NDK subdirectories so glog/boost/folly/fmt never see it, and this project never compiles app or third-party module code — those build against the prefab artifacts through `ReactNative-application.cmake`. For that reason the flag deliberately does NOT go into `target_compile_reactnative_options`, which app and third-party module builds do call. - SwiftPM: one `.define` in the shared `Target.reactNativeTarget` factory that every React Native target is created through. `cxxSettings` are per-target and are not inherited by packages that depend on React. - Buck: a `_set_rn_building_flag` helper called from the four macros React Native's own targets use. These macros are also used by ~300 product packages that *consume* React Native, and those must stay subject to the guards, so the flag is scoped by package prefix rather than applied unconditionally. It is `preprocessor_flags`, deliberately not `exported_preprocessor_flags`, so dependents are not exempted either. This change is inert on its own: nothing behaves differently unless a consumer defines `RN_STRICT_API`. Changelog: [Internal] Differential Revision: D115051088
