## Description

SocketRocket is an Objective-C WebSocket client library designed to establish bidirectional real-time communication channels between an application and a server. It provides a networking layer for real-time data streaming, utilizing a heartbeat monitor to maintain the stability of active network streams.

The library is built to operate across restricted networks by routing traffic through HTTP proxies. It secures data transmission using TLS encryption and SSL certificate pinning to prevent unauthorized interception of network traffic.

Its underlying capabilities include low-level TCP socket integration, stream-based frame parsing, and an HTTP handshake upgrade protocol. The system tracks connection lifecycles via an event-driven state model to notify the host of open, close, and error events.
