I was able to download a local geodatabase replica, but when attempting to execute Sync method to download/upload changes nothing is happen, neither Status block or Completion block is executed. I've performed local changes and Server side changes still nothing....
Used example from here: https://developers.arcgis.com/ios/guide/sync-offline-edits.htm Downloaded data is include (.geodatabase, .geodatabase-shm, .geodatabase-wal ) Service configuration is: Sync Capabilities: Supports Registering Existing Data: true Supports Sync Direction Control: true Supports PerLayer Sync: true Supports PerReplica Sync: false Supports RollbackOnFailure : false Supports Async: true
