  • Explanation: The AppKit/UIKit overlay refers to symbols declared via NS_OPTIONS macro, which is causing issues in the C++ language mode due to the macro definition being different. This teaches the module interface loader to drop the C++ interop flag when rebuilding the AppKit/UIKit overlays from their interface.
  • Scope: This changes the compiler flags used to rebuild AppKit/UIKit when C++ interop is enabled.
  • Issues: rdar://143033209
  • Original PRs: [cxx-interop] Workaround compiler error when importing AppKit/UIKit with C++ interop #78694
  • Risk: Low, this only affects rebuilding of a single SDK module from its interface when C++ interop is enabled.
  • Testing: Unit testing, manual testing against code where this was discovered.
  • Reviewers: @Xazax-hun

This is the same as #78657 but with different modules.

The AppKit/UIKit overlay refers to symbols declared via NS_OPTIONS
macro, which is causing issues in C++ language mode due to the macro
definition being different. This teaches the module interface loader to
drop the C++ interop flag when rebuilding the AppKit and UIKit overlay
from its interface.

This is the same fix as swiftlang#78636, but for different modules.

We resolved this with a different workaround approach, I'm going to decline this.
