iOS: updateOSDeploymentTarget skips resource-bundle targets, so Xcode 27 fails the build with "deployment target ... supported range is 15.0"

Description

Xcode 27 (27A266a, iOS 27.0 SDK) turns "deployment target below the supported range" from a warning into a hard build error, and the supported range now starts at iOS 15.0. A React Native app fails to build because several CocoaPods resource-bundle targets still carry the deployment target declared in their podspec s.platform (9.0 / 12.4 / 13.4 / 14.0).

react_native_post_install already lifts pod targets to min_ios_version_supported via ReactNativePodsUtils.updateOSDeploymentTarget, but that method only iterates target_installation_result.native_target:

https://github.com/react/react-native/blob/a17fbb48e065a0ba0328538f997ae08b228be6af/packages/react-native/scripts/cocoapods/utils.rb#L435-L445

Each pod's resource_bundle_targets (PrivacyInfo bundles, asset bundles) are never visited, so they keep the podspec value and Xcode 27 rejects them. The library targets of the very same pods build fine because they were floored to 15.1; only their resource bundles fail. The method is identical on main, 0.87.1 and 0.83.10.

Fixing this per-package is not viable: the newest releases of react-native-device-info (15.0.2), react-native-image-picker (8.2.1), react-native-svg (15.15.5) and RiveRuntime (6.23.1) still declare platform minimums below 15, and a resource bundle's deployment target is assigned by CocoaPods, not by anything the app controls. Since React Native already owns the deployment-target floor for library targets, the floor should cover resource-bundle targets too.

Proposed fix

turn_off_resource_bundle_react_core in the same file already iterates resource_bundle_targets (https://github.com/react/react-native/blob/a17fbb48e065a0ba0328538f997ae08b228be6af/packages/react-native/scripts/cocoapods/utils.rb#L141), so this is the same traversal RN uses elsewhere:

def self.updateOSDeploymentTarget(installer)
    min_version = Helpers::Constants.min_ios_version_supported
    installer.target_installation_results.pod_target_installation_results
        .each do |pod_name, target_installation_result|
            targets = [target_installation_result.native_target] + target_installation_result.resource_bundle_targets
            targets.each do |target|
                target.build_configurations.each do |config|
                    old_iphone_deploy_target = config.build_settings["IPHONEOS_DEPLOYMENT_TARGET"] ?
                        config.build_settings["IPHONEOS_DEPLOYMENT_TARGET"] :
                        min_version
                    config.build_settings["IPHONEOS_DEPLOYMENT_TARGET"] = [min_version.to_f, old_iphone_deploy_target.to_f].max.to_s
                end
            end
        end
end

Happy to open a PR with this change if maintainers prefer.

Workaround

In the app Podfile post_install, after react_native_post_install:

installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
    if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < min_ios_version_supported.to_f
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = min_ios_version_supported
    end
  end
end

With this in place all 260 IPHONEOS_DEPLOYMENT_TARGET entries in Pods.xcodeproj read 15.1 and the build succeeds on Xcode 27.

Steps to reproduce

1. npx @react-native-community/cli init Repro --version 0.83.1 (also reproduces with 0.87.1).
2. Add any dependency whose podspec declares an old platform and ships a PrivacyInfo.xcprivacy resource bundle, e.g. react-native-device-info@15.0.2 (s.platforms = { :ios => "9.0" }).
3. cd ios && RCT_NEW_ARCH_ENABLED=1 pod install.
4. grep "IPHONEOS_DEPLOYMENT_TARGET = " Pods/Pods.xcodeproj/project.pbxproj | sort | uniq -c shows the library target at 15.1 and RNDeviceInfo-RNDeviceInfoPrivacyInfo at 9.0.
5. Build with Xcode 27 for any iOS 27 destination (simulator or device). The build fails at the project validation step before compiling anything.

MANDATORY Reproducer

The defect is in packages/react-native/scripts/cocoapods/utils.rb itself (permalink above); the steps above reproduce it on a fresh cli init app with one dependency added and no other changes. I can push a repro repository if the steps are not sufficient.

No response

Beginnen Sie in packages/react-native/scripts/cocoapods/utils.rb bei ReactNativePodsUtils.updateOSDeploymentTarget und vergleichen Sie dessen Durchlauf mit turn_off_resource_bundle_react_core. Reproduzieren Sie dies mit der aufgeführten CLI-App und Abhängigkeit und untersuchen Sie anschließend Pods/Pods.xcodeproj/project.pbxproj; abgeschlossen ist die Arbeit, wenn die Deployment Targets der Resource Bundles min_ios_version_supported entsprechen und die Xcode 27-Validierung erfolgreich ist.
