Starting with version 100.11, you can take certain utility network information offline. Associations, which are used to describe containment, structural attachment, and connection between features with non-coincident geometry, can be queried and displayed with offline data. Simple edits can also be made to utility network features while offline and synchronized back to ArcGIS Enterprise.
For more information about offline workflows using ArcGIS Maps SDKs for Native Apps, see the Offline maps, scenes, and data topic.
