This PR enables all Apple bundle rules (
ios_framework,ios_application,macos_application, etc.) to propagate output groups from their dependencies, particularly Swift-related output groups fromswift_librarytargets. This is to support work I did in bazelbuild/rules_swift#1628 to output diagnostic files.Previously, output groups like
swift_index_storewere only available directly onswift_librarytargets. This made it difficult to collect supplemental compilation outputs (diagnostics, indexstore, AST files, etc.) when Swift code was built as part of a framework or application bundle.Full disclosure: most of these changes were made using Cursor and only verified on 1 project.
