Networking Diagnostics

概要

Provides a systematic approach to debugging network layer issues in modern xOS development by focusing on Network.framework best practices. This skill guides developers through production crisis defense, offering structured diagnostic patterns for common failures like DNS timeouts, certificate validation errors, and message framing problems. It emphasizes real-device testing and provides clear decision trees to identify root causes in minutes rather than hours, ensuring robust network implementation for iOS, iPadOS, watchOS, and tvOS applications while avoiding common pitfalls like unnecessary socket rewrites.
