Worked on the ggml-org/llama.cpp repository to deliver Apple XCFramework build support for the libmtmd C API, enabling direct Swift and Objective-C integration. Used CMake and Shell scripting to introduce an opt-in build option, allowing libmtmd to be packaged as a standalone component without requiring the full tools tree. Updated build scripts to include static libraries and headers in the framework, ensuring the C API is accessible for downstream Apple platforms. Focused on cross-platform development and packaging reliability, the work reduced integration friction for bindings and applications targeting iOS, tvOS, and visionOS, while maintaining lightweight, gated builds.
