@nirinchev @elle-j This is not complete, but I thought it would be good to have an initial feedback.
What I think it's missing:

• Try to reduce the internal API methods
• Retrieve the complete schema from realm (not only the model and extra properties)
• Tests for queries/keypath/notifications (these requires the core implementation too)
