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.

使用具有非同步/等待、結構化並發和現代 Swift 模式的 URLSession 在 iOS/macOS 應用程式中建立、審查或改進網頁程式碼。使用 REST API、下載檔案、上傳資料、WebSocket 連線、分頁、重試邏輯、請求中間件、快取、背景傳輸或網路可達性監控時使用。觸發涉及 HTTP 請求、API 用戶端、網路錯誤處理或 Swift 應用程式中的資料擷取的任何任務。 來源：dpearson2699/swift-ios-skills。
