ios-networking

Modern networking patterns for iOS 26+ using URLSession with async/await and structured concurrency. All examples target Swift 6.2. No third-party dependencies required -- URLSession covers the vast majority of networking needs.

URLSession gained native async/await overloads in iOS 15. These are the only networking APIs to use in new code. Never use completion-handler variants in new projects.

Always validate the HTTP status code before decoding. URLSession does not throw for 4xx/5xx responses -- it only throws for transport-level failures.

Build, review, or improve networking code in iOS/macOS apps using URLSession with async/await, structured concurrency, and modern Swift patterns. Use when working with REST APIs, downloading files, uploading data, WebSocket connections, pagination, retry logic, request middleware, caching, background transfers, or network reachability monitoring. Trigger for any task involving HTTP requests, API clients, network error handling, or data fetching in Swift apps. Source: dpearson2699/swift-ios-skills.
