Storage

Mobile SDKs for feature management and experimentation are designed to operate efficiently on iOS devices. Unlike server-side SDKs, mobile SDKs utilize built-in storage to manage feature flags and experimentation data.

Purpose of of Storage

The primary purpose of using storage in mobile SDKs is to enhance performance and ensure a consistent user experience. By caching feature flag decisions locally, mobile applications can quickly access necessary data without repeatedly querying the server.

By combining UserDefaults for quick-access caching and Core Data for complex data persistence, the SDK ensures efficient, reliable feature flag management and a seamless user experience.

Key Benefits

  • Persisting feature flag decisions ensures that users have a consistent experience, even if they close and reopen the app.
  • Once a decision is made for a user, it remains consistent, even if campaign settings are modified. This stability is crucial for accurate A/B testing and controlled feature rollouts.
  • Caching decisions locally reduces the need for constant server communication, leading to faster response times and a smoother user experience.
