Network Framework Migration Guides

Do I Need to Migrate?

What networking API are you using?

├─ URLSession for HTTP/HTTPS REST APIs?
│   └─ Stay with URLSession — it's the RIGHT tool for HTTP
│      URLSession handles caching, cookies, auth challenges,
│      HTTP/2/3, and is heavily optimized for web APIs.
│      Network.framework is for custom protocols, NOT HTTP.
│
├─ BSD Sockets (socket, connect, send, recv)?
│   └─ Migrate to NWConnection (iOS 12+)
│      → See Migration 1 below
│
├─ NWConnection / NWListener?
│   ├─ Need async/await? → Migrate to NetworkConnection (iOS 26+)
