Build a Swift API client by implementing a protocol-based design that separates transport from business logic using URLSession and async/await. This approach ensures your networking layer is robust, testable, and easy to maintain across iOS and macOS apps.

Handle JSON decoding and errors in a Swift API client by applying configurable decoding strategies alongside structured error handling. This ensures network failures and data mismatches are caught and processed cleanly within your async/await networking flows.

Implement retry logic with exponential backoff in Swift networking by applying structured resilience strategies to your URLSession requests. This allows your API client to automatically recover from transient failures and manage authentication flows effectively.

Yes, you can use this protocol-based API client approach across both iOS and macOS apps. The design utilizes native URLSession and async/await features, ensuring broad compatibility and consistent networking behavior throughout the Apple ecosystem.

Test an async Swift API client without real network calls by leveraging the protocol-based design to inject mock transport layers. This separates your business logic from URLSession, allowing you to verify decoding, error handling, and retries deterministically.

Swift async URLSession requests may fail to handle timeouts and caching properly without structured guidance for these configurations. Implementing a protocol-based API client ensures you establish explicit rules for caching, timeouts, and background transfers.
