Apple Platform Networking

About

Provides comprehensive guidance for implementing high-performance networking on iOS, iPadOS, watchOS, and tvOS using the modern Network.framework. It helps developers transition from legacy sockets and URLSession streams to robust UDP/TCP connections, specifically addressing the shift toward structured concurrency in iOS 26+. By enforcing best practices like proper connection state handling and avoiding main-thread blocking, the skill ensures reliable network transitions and efficient resource usage in production environments.

Key Features

• Built-in patterns for TLS security, QUIC, and custom protocol framing
• Guidance for handling network transitions and low-data modes
• Implementation of TCP/UDP connections using Network.framework and structured concurrency
• Strategies for debugging connection timeouts and TLS handshake failures
• Prevention of deprecated reachability anti-patterns and legacy BSD socket usage
• 61 GitHub stars

Use Cases

• Implementing low-latency UDP connections for real-time gaming or streaming
• Adopting async/await networking patterns for iOS 26+ applications
• Migrating legacy SCNetworkReachability or BSD socket code to modern Apple APIs
