Network Framework Reference

About

Empowers developers to build high-performance, secure networking layers for Apple platforms by providing deep insights into Network.framework. It offers a side-by-side comparison between legacy completion-handler APIs and modern structured concurrency models, alongside detailed implementation patterns for custom protocols using TLV framing and the Coder protocol. Whether you are optimizing for low-latency gaming, peer-to-peer discovery via Wi-Fi Aware, or migrating away from Berkeley sockets, this skill serves as the definitive guide for leveraging user-space networking and smart connection establishment in modern iOS development.

Key Features

• Guidance on peer-to-peer discovery using NetworkBrowser and Wi-Fi Aware
• Implementation patterns for built-in TLV framing and the type-safe Coder protocol
• 60 GitHub stars
• Best practices for smart connection establishment, including Happy Eyeballs and proxy evaluation
• Comprehensive API reference for NWConnection and the modern NetworkConnection
• Migration strategies for moving from BSD sockets and completion handlers to structured concurrency

Use Cases

• Implementing custom low-level protocols like UDP, QUIC, or WebSocket for gaming and streaming applications
• Migrating legacy networking code from BSD sockets or completion handlers to modern Swift async/await
• Setting up infrastructure-free peer-to-peer discovery and communication between nearby Apple devices
