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
