Rolling your own Network Stack
summary
Shows a concrete Swift network stack: uses URLSession, Codable and generics to build an API router enum that produces URLRequests, a NetworkService wrapping an OperationQueue, and a generic NetworkOperation subclass that decodes Decodable models (example: New York Times Bestsellers). Adds practical extensions: request adapter for auth headers, retry logic for OAuth token refresh, custom URLSession for pinning/caching, and custom decoders for weird JSON. Stack replaced an existing client at Coop to support a second API and works in production.
