networking-layer

Build a Swift networking layer using async/await by defining a protocol-based API client with endpoint abstractions. This approach provides typed errors and swappable implementations, enabling clean REST API communication and reducing boilerplate across iOS and macOS apps.

Mock an API client for Swift unit tests by using a protocol-based networking layer. Swappable implementations allow you to substitute URLSession with custom mock clients, verifying fetch-or-create data patterns and endpoint behavior without real network calls.

Yes, the async/await networking layer supports custom URLSession clients through its protocol-based design. You can swap the default URLSession implementation for custom clients or mocks, ensuring testability and flexible configuration across iOS and macOS projects.

Handle typed errors in a Swift API client by defining robust error handling within your protocol-based networking layer. This provides clear, typed error propagation during async/await fetch operations, replacing generic errors with specific, actionable configurations for base URL and authentication failures.

Yes, you can configure base URL and authentication options for a Swift REST API client. The networking layer provides configuration options for base URL and authentication, alongside optional logging or retries, ensuring flexible setup for various endpoint requirements.

Use protocol-based networking instead of direct URLSession calls to achieve swappable implementations and robust error handling. This architecture decouples API endpoint definitions from execution, making it easy to inject mocks for unit testing and reducing boilerplate across iOS and macOS apps.
