Summary

Many applications require the ability to refresh their data displays, and implementing a pull-to-refresh feature with Sync Gateway and Couchbase Lite for iOS is a practical approach. Sync Gateway facilitates data sharing and access control through the use of channels, allowing replication to be channel-specific, which means only relevant documents are synchronized. In a given configuration, a guest account can access specific channels, such as the public_recipes channel, to which documents of a certain type are routed. To insert documents, Sync Gateway's REST API is used, enabling the creation of new entries that can be fetched during refresh actions. On the iOS side, initiating a pull replication when the gesture is detected allows for data refresh, with notifications signaling when replication is complete, prompting a table view reload. The example source code for implementing this feature can be accessed on GitHub.
