Can it help debug TLS handshake failures?

Absolutely. It features dedicated diagnostic logic specifically for TLS issues, connection drops, and certificate problems.

Is it optimized for Swift structured concurrency?

Yes, one of the primary focuses is implementing networking using async/await and modern concurrency patterns.

Does this skill support legacy versions of iOS?

Yes, it includes specialized routing for iOS 12-25 patterns and provides clear migration paths to the latest networking standards.

Does it support WebSockets and TCP?

Yes, it provides implementation patterns and reference material for WebSockets, TCP connections, and TLV framing.

How does it handle existing custom networking code?

The skill is designed to diagnose existing issues first and provide technical guidance on whether to fix the custom implementation or migrate to standard APIs for better stability.
