Module objc 

Minimal Objective-C runtime bridge.

AppKit and UIKit classes are reached through objc_msgSend rather than the Swift calling convention — that is their native ABI, so nothing is lost.

Every send goes through a correctly-typed, non-variadic view of objc_msgSend. On arm64 variadic arguments are passed on the stack, so calling a variadic declaration with real arguments delivers them where the receiver never looks and the callee reads uninitialised registers instead.
