PylibKit lets iOS/macOS apps use Python libraries—including C-extension and Rust-backed wheels—without exposing Python to app code. Everything is bundled into a single Swift XCFramework. You call generated Swift services with async/await, receive Swift types, and never touch PythonObject. We handle CPython, pinned wheels, asyncio safety, threading, signing, and reproducible builds—so app teams can focus on features, not toolchains.
