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.
