Offline caching and data synchronization in iOS apps require combining URLSession API communication with local persistence backends like Core Data or disk caches. This Skill provides patterns to fetch data, cache responses locally, and enable offline access by reading from storage when the network is unavailable.

Secure token management and data persistence in iOS networking are best handled by storing credentials in Keychain while using multiple backends like UserDefaults, Core Data, Realm, or SQLite for application data. This Skill demonstrates integrating these persistence options with endpoint-based URLSession requests.

URLSession supports WebSocket connections for real-time messaging in Swift through its native WebSocketTask API. This Skill consolidates best practices for implementing WebSocket support alongside standard endpoint-based requests and comprehensive error handling.

Core Data and Realm can be used together for different persistence needs in an iOS app, alongside UserDefaults, SQLite, and disk caches. This Skill covers multiple persistence backends to handle various real-world scenarios, allowing you to choose the appropriate storage mechanism for your specific data.

Handling API communication errors with endpoint abstractions in iOS involves structuring URLSession requests around typed endpoints with centralized error handling logic. This Skill demonstrates these patterns to enable robust API communication and streamline error management across your networking layer.
