The purpose of Fabric is not to recreate a Twitter client, but to embed relevant content into other apps, so there is no method to embed a home timeline - this is the same as for our embedded timelines on the web, by the way. I’m not aware of a plan to change that, but we’ll definitely add it to the possible enhancement bucket.
You’re free to use the TwitterApiClient to grab a user’s home timeline via the regular API, and hydrate a table view using that.
