How would you design a Swift-based system to handle unpredictable backend latency spikes?

Updated May 17, 2026

Short answer

Use timeouts, fallback data, caching, and adaptive retry strategies.

Deep explanation

Latency spikes must not freeze UI. Systems should use cached responses while background refresh updates data. Timeouts prevent blocking, and fallback UI ensures continuity. Adaptive retries reduce backend overload.
