Working with C and C++ in Apple environment
summary
Argues for embedding C/C++ to share domain logic across iOS, macOS, Android and Windows, showing a working integration: a header-only JSON library as a single-file example, Swift Package Manager needs an add empty .cpp to satisfy SwiftPM workaround, and larger C++ libs compile to XCFrameworks and link fine though binaries grow unless linker strips unused slices. Recommends hiding C++ with a Swift wrapper + protocol for UI mocks, uses OpaquePointer and passRetained for async callbacks, tests with Google Test, and notes C++ interop in Xcode 15 early but usable.
