Core principle 85% of networking problems stem from misunderstanding connection states, not handling network transitions, or improper error handling—not Network.framework defects.

Network.framework is battle-tested in every iOS app (powers URLSession internally), handles trillions of requests daily, and provides smart connection establishment with Happy Eyeballs, proxy evaluation, and WiFi Assist. If your connection is failing, timing out, or behaving unexpectedly, the issue is almost always in how you're using the framework, not the framework itself.

This skill provides systematic diagnostics to identify root causes in minutes, not hours.
