## What it is
CocoaAsyncSocket is an asynchronous TCP and UDP socket networking library for macOS, iOS, and tvOS, built on Grand Central Dispatch. It provides Objective-C classes (GCDAsyncSocket and GCDAsyncUdpSocket) with delegate-based, non-blocking read/write operations.

## Use cases
- add TCP client/server networking to an iOS app
- implement async UDP communication on macOS
- build a socket-based protocol in Objective-C or Swift
- handle non-blocking socket reads and writes with timeouts
- stream data over TCP without blocking the main thread

## When to choose
- you need battle-tested async TCP/UDP sockets on Apple platforms
- you want a self-contained Objective-C library with delegate callbacks
- you need CocoaPods, Carthage, or SPM integration

## When to avoid
- you are targeting non-Apple platforms
- you prefer Swift-native networking like Network.framework
- you need higher-level HTTP or WebSocket abstractions

## Facets
- artifact type: library
- maturity: stable
- function: networking, concurrency
- domain: networking, developer-tools, cross-platform
- platform: cpp
- tags: tcp, udp, objective-c, sockets, gcd, apple-platforms, cocoapods, macos, ios, swift
