We encourage you to try our Couchbase Lite 2.0 Developer Builds (DB’s): https://developer.couchbase.com/documentation/mobile/2.0/whatsnew.html?language=ios that includes Swift. We are looking at a 2.0 Beta late Summer. As far as how many DB’s we will have, a lot depends on the feedback we receive from developers like you! We are completely revamping the Couchbase Lite API and getting developer feedback is crucial to know if what we’re doing that’s right and what needs to change.
