Couchbase Mobile data platform offers the capability to sync data across mobile clients using Couchbase Lite and the Sync Gateway, with specific support for running apps in the background on iOS, Android, and .Net platforms to ensure up-to-date data on app launch. The tutorial introduced focuses on leveraging iOS's Background App Refresh feature to sync data in the background, using a Swift-based "User Profile" app as an example. It demonstrates configuring the app to perform a one-shot sync with the Couchbase Sync Gateway when the app is activated in the background. This ensures the user profile information is kept current, syncing with a remote server and other devices, subject to access control. The guide highlights that while the tutorial is iOS-specific, similar concepts apply to other platforms, and encourages users to explore Silent Notifications as an alternative background mode.
