Summary:

This fixes a bug that started with React Native 0.72.0 when using the new architecture and installing a native lib that has Swift code (in my case, @datadog/mobile-react-native).

Running pod install errors with the following output (DatadogSDKReactNative is the pod containing the Swift code):

[...]
Analyzing dependencies
Downloading dependencies
Installing DatadogSDKReactNative 1.8.0-rc0
[!] The following Swift pods cannot yet be integrated as static libraries:

The Swift pod `DatadogSDKReactNative` depends upon `React-Fabric`, `React-graphics`, `React-utils`, and `React-debug`, which do not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies.

Indeed, this pods were added as dependencies in packages/react-native/scripts/cocoapods/new_architecture.rb but do not define modules contrary to the other pods in the list.

This PR is solving a problem that already occured in the past and was solved here: #33743
It's a new implementation for the PR initially opened here: #38039

Changelog:

[IOS] [FIXED] - Fix pod install for libraries using Swift code when the new architecture is enabled

Test Plan:

  1. Clone this repo
  2. From main, add a Swift file to the MyNativeView native module in the RN tester app (see inspiration from this commit)
  3. Try to run RCT_NEW_ARCH_ENABLED=1 USE_HERMES=0 bundle exec pod install inside the packages/rn-tester
  4. Observe errors
  5. Apply the commit from this PR
  6. Both pod install and the subsequent build should succeed.
  7. Revert the changes and repeat steps 2 to 6 with RCT_NEW_ARCH_ENABLED=1 USE_HERMES=1 bundle exec pod install

When adding "DEFINES_MODULE" => "YES" to s.pod_target_xcconfig in packages/react-native/third-party-podspecs/glog.podspec I still get the following error:

[!] The following Swift pods cannot yet be integrated as static libraries:

The Swift pod `MyNativeView` depends upon `glog`, which does not define modules.

yeah, glog is a different beast as it is a c++ library we don't own and that does not actually support Cocoapods. So we are doing some black magic to make it work.

posting an update here so it's easier to catch up once @cipolleschi is back: this commit only works on Xcode >=14.3, and breaks for both new and old arch for anything lower (see #38294).

To discuss the general situation and approach, there's now this react-native-community/discussions-and-proposals#687 - but I'm writing a comment here because we need to decide two things:

  1. is there a way to change this code to work also in version of Xcode lower than 14.3? if so, we could re-port this in the 0.72 branch with the extra patch for older versions of Xcode
  2. if that's not possible, do we need to revert this also on main?
