Get sync status and not synced documents

Hello,

we are investigating Couchbase for a new project. We are currently using version 1.4 on iOS.
Currently there are there questions:
1.) Is there a way to get the current connection status?
2.) Is there a way to get the status of the sync?
3.) How can I get all not synced documents?

Thanks for your help,
Stefan Sturm

In 1.4, you can register for kCBLReplicationChangeNotification notification and get the status of replication from ReplicationStatus .

You can use pendingDocumentIDs to get list of documents that have not yet been pushed up.

Docs at https://developer.couchbase.com/documentation/mobile/1.4/references/couchbase-lite/couchbase-lite/replication/replication/index.html give you the details.
