The `[Hermes] Replace Hermes for the right configuration, if needed` script_phase has no declared outputs because it overwrites the prebuilt Hermes binary in place based on `$CONFIGURATION`. Xcode 14+ emits "will be run during every build because it does not specify any outputs" on every clean build of every project on the prebuilt-release tarball path. Set `script_phase[:always_out_of_date] = "1"` guarded by a `Pod::VERSION >= 1.13.0` check. Apple's documented opt-in for "yes, this phase intentionally runs every build." The phase still runs every build. The warning downgrades to a `note`. Matches the existing shape of the two sibling `Replace X for the right configuration` script_phases in the same package: - `React-Core-prebuilt.podspec` (react#52133) - `third-party-podspecs/ReactNativeDependencies.podspec` (react#49812) Same property previously accepted in react#48495 (`088fcb1e5d`) for `React-RCTFBReactNativeSpec.podspec` and the codegen podspecs (later consolidated in react#50317). `hermes-engine` is the last `Replace X` phase in the package without it.
