Can I use this for peer-to-peer discovery?

Absolutely. It provides comprehensive patterns for NWBrowser and Bonjour advertising to discover services on local networks without hardcoded IP addresses.

How do I migrate these patterns to modern iOS versions later?

The Axiom suite includes the axiom-networking-migration skill to help transition these completion handler patterns to async/await for iOS 26+ targets.

Why should I use legacy patterns instead of modern async/await?

These patterns are necessary when your app must support iOS versions between 12 and 25, or when working in a codebase that has not yet transitioned to modern Swift Concurrency.

What are the performance benefits of the UDP batching pattern?

The UDP batching pattern reduces context switches by grouping multiple datagrams into a single syscall, which can reduce CPU usage by approximately 30%.

Does this skill support secure connections?

Yes, it includes specific patterns for NWConnection with TLS to ensure encrypted communication on older iOS runtimes.

Mobile Development

Provides battle-tested NWConnection patterns for iOS 12-25 applications using completion handlers and legacy networking APIs.

关于

The axiom-networking-legacy skill is a specialized tool for developers maintaining or building apps for older xOS environments (iOS 12-25). It offers optimized, production-grade patterns for NWConnection, NWListener, and NWBrowser that utilize completion handlers rather than modern async/await syntax. This is essential for legacy codebases, libraries requiring broad backward compatibility, or high-performance networking tasks like UDP batching and Bonjour discovery on devices that do not support the latest operating system runtimes.
