## Description

Shadowsocks-iOS is a proxy client for iOS devices that implements the Shadowsocks protocol to tunnel network traffic through a secure, encrypted relay. Its primary purpose is to route device traffic through a proxy server to bypass network censorship and regional restrictions.

The project establishes secure proxy tunneling to protect data from local monitoring and hide internet activity. It manages iOS network traffic routing using custom encryption protocols to avoid network interference.

The implementation utilizes a system-level network extension framework and a local virtual network interface to intercept and route device IP traffic. It supports packet-level encryption, the SOCKS5 proxy protocol, and bidirectional TCP and UDP stream forwarding.
