List Databases in CouchbaseLite

Is there any API call in CouchbaseLite (Swift) that lists all databases I have created in a mobile app?

Which version of CBL are you using?
If its 1.x, then you can use allDatabaseNames .
I don’t think we have an equivalent in CBL 2.0 (@pasin)

Unfortunately I endeavored into the 2.0 world

You’ll need to track that yourself, the same way that you could keep track of regular files you create. For example you can create a directory and put your databases in that directory; then you can just use NSFileManager to iterate the contents of that directory.
