apple/swift-nio

SwiftNIO is a high-performance, event-driven networking framework for Swift that provides low-level I/O primitives and high-level abstractions for building networked applications. The system supports multiple transport protocols including TCP, UDP, and Unix domain sockets, with specific implementations for Linux, macOS, Windows, and other platforms. It includes comprehensive tooling for performance benchmarking, memory allocation tracking, and integration testing to ensure stability and correctness across diverse environments.

This period focused on expanding the library's capabilities with comprehensive HTTP/1.1 support, including header validation, pipelining, and a sample server application. It also introduced TLS negotiation handlers for ALPN and SNI, alongside new WebSocket upgraders and a multicast chat example. Underlying these features were significant improvements to concurrency primitives, cross-platform C shims, and extensive integration testing.

This period focused on integrating Swift's async/await concurrency model into SwiftNIO, introducing new async-safe testing primitives and bridging APIs. The team also expanded the codebase with numerous sample applications, enhanced the internal test framework for memory and resource tracking, and added Windows support.

This period focused on deepening Swift Concurrency support by introducing NIOAsyncChannel and NIOAsyncSequence primitives for back-pressure-aware I/O. Simultaneously, the team built out the NIOFileSystem module, adding buffered I/O utilities, low-level system call wrappers, and Foundation interoperability.
