How do you design networking on iOS (URLSession, retries, caching, error handling)?
Answer
A robust networking layer wraps URLSession with consistent request/response handling.
Include:
- Typed endpoints and decoding
- Timeouts and retry policies (idempotent only)
- Caching when safe
- Auth token refresh
- Clear error mapping for UI
Keep the API surface small and testable with mock sessions.
