Event driven networking for Swift
summary
SwiftNIO (Netty for Swift) is a low‑level, nonblocking I/O framework that claims to let one thread multiplex hundreds of thousands of concurrent connections by using per‑thread event loops, copy‑on‑write byte buffers, and a channel pipeline of handlers (examples: SSL handler, backpressure handler, echo handler). The talk shows a working encrypted echo server, explains bootstraps, promises for async operations, and notes the project is open source on GitHub and already prompted an ARC optimization in the Swift compiler.
