Swift NIO, Vapor, and Server Concurrency

on YouTube ↗21m

" summary

Explains why Swift NIO replaces a thread‑per‑connection model in Vapor, moving from POSIX threads and libdispatch blocking to an evented nonblocking I/O core that lets a single thread serve many connections, issue multiple external API calls concurrently, and avoid idle CPU while waiting for responses. Shows integration into Vapor 3, uses futures for asynchronous chaining, leverages built in HTTP and WebSocket parsers, and reports concrete gains in resource efficiency and ecosystem reliability.
