Summary: there are build errors happened when in [`generate_multiple_pod_projects`](https://blog.cocoapods.org/CocoaPods-1.7.0-beta/#multiple-xcodeproj-generation) mode and fabric is on. since we have multiple pod projects, there are something breaks. ### `-DRCT_NEW_ARCH_ENABLED=1` does not pass to `RCTAppSetupUtils.mm` because `installer.pods_project` is targeting `Pods.xcodeproj` but not `React-Core.xcodeproj`. we should use ` installer.target_installation_results.pod_target_installation_results` to deal with `generate_multiple_pod_projects` mode. ### fatal error: 'CompactValue.h' file not found ``` In file included from /path/to/react-native/packages/rn-tester/build/generated/ios/react/renderer/components/rncore/Props.cpp:11: In file included from /path/to/react-native/packages/rn-tester/Pods/Headers/Private/React-Codegen/react/renderer/components/rncore/Props.h:13: In file included from /path/to/react-native/packages/rn-tester/Pods/Headers/Private/React-Fabric/react/renderer/components/view/ViewProps.h:11: In file included from /path/to/react-native/packages/rn-tester/Pods/Headers/Private/React-Fabric/react/renderer/components/view/YogaStylableProps.h:10: /path/to/react-native/packages/rn-tester/Pods/Headers/Public/Yoga/yoga/YGStyle.h:16:10: fatal error: 'CompactValue.h' file not found #include "CompactValue.h" ^~~~~~~~~~~~~~~~ 1 error generated. ``` `Props.cpp` -> `YogaStylableProps.h` -> `YGStyle.h` -> `CompactValue.h` [`CompactValue.h` is internal private header for Yoga pod](https://github.com/facebook/react-native/blob/4eef075a583224ec9da6bbc4b42bc52508eb31be/ReactCommon/yoga/Yoga.podspec#L54-L56) where `React-Codegen` project cannot access to. ~there are some solutions toward this problem. one way is to make other yoga headers as public headers. i am not sure whether this solution would introduce any side effects. so i only make necessary projects to search yoga private headers.~ Update: a solution is to expose all yoga headers publicly. however, CocoaPods will put all public headers to module umbrella header. this will break YogaKit (swift) integration because swift module doesn't support c++. my pr is trying to expose all yoga headers to `$PODS_ROOT/Headers/Public/Yoga/yoga`, but use custom `module_map` to control which headers should be exposed to the swift module. CocoaPods's custom module_map has some limitation where cannot well support for both `use_frameworks!` mode and non use_frameworks! mode. there's a workaround to use `script_phase` copying the umbrella header to right place. ## Changelog [iOS] [Fixed] - Fix iOS build error when Podfile `generate_multiple_pod_projects=true` and Fabric is on Pull Request resolved: https://github.com/facebook/react-native/pull/33381 Test Plan: verify with rn-tester 1. add `generate_multiple_pod_projects` ```diff --- a/packages/rn-tester/Podfile +++ b/packages/rn-tester/Podfile @@ -5,7 +5,7 @@ platform :ios, '11.0' # Temporary solution to suppress duplicated GUID error. # Can be removed once we move to generate files outside pod install. -install!
