Build a Swift networking layer by implementing a protocol-based API client architecture with decoupled endpoint definitions. This approach utilizes native Swift concurrency with async/await to fetch JSON and handle errors robustly over URLSession-backed clients.

Structuring a protocol-based API client involves creating modular configurations with typed errors and swappable implementations. This design reduces boilerplate and improves testability by decoupling endpoint definitions from the core URLSession networking logic.

Yes, you can swap URLSession implementations because the networking layer relies on protocol-based architecture. This modular design allows you to configure alternative clients seamlessly without making extensive changes to your existing codebase.

Handle errors and add retry logic in your Swift API client by defining typed errors within your protocol configuration. The modular architecture supports optional logging and retry components to manage network failures robustly during async/await requests.

No third-party dependencies are required for Swift concurrency, as the networking layer operates entirely on native Swift async/await and URLSession. It delivers a robust, dependency-free core architecture suitable for modular API configuration.

Use a protocol-based networking layer instead of direct URLSession calls to achieve decoupled, modular configuration with swappable implementations. This architecture minimizes boilerplate, improves testability, and supports typed errors and optional retry components natively.
