SwiftNet – C networking library (macOS-only for now, needs Linux testers)

Hello dear people,

I’m working on SwiftNet, a small and easy-to-use C library for making networking communications in C straightforward. It’s a wrapper over Berkeley sockets with a simple API, readable, and easy to integrate.

Right now, it’s only been tested on macOS, so I’m looking for contributors to:

Test it on Linux Suggest improvements Help refine the design/API The codebase is pretty small, and while the API is straightforward, the internals are admittedly a bit rough right now. I’m still learning and improving!

Why I built this:

I wanted to create a C library that makes sending data over the network reliable and easy, while learning more about low-level networking and systems design. Everything is written in pure C, built with a basic CMake setup, and has no external dependencies.

Example usage:

// Server sends "hello" to every client that sends a message void server_message_handler(uint8_t* data, SwiftNetPacketServerMetadata* metadata) { swiftnet_server_append_to_packet(server, "hello", strlen("hello")); swiftnet_server_send_packet(server, metadata->sender); swiftnet_server_clear_send_buffer(server); }

How you can help: Test on Linux: clone, build with cmake, and run the tests in /tests Suggest improvements to the overall library or code clarity Share ideas for future features

Thanks for checking it out! Ask me anything.
