QUESTION
I have a query that provides 'feed' data to a collection view using RxSwift and RxFirebase. This feed data now has a 'Privacy' field (possible values: "Public", "Sub", and "Private") and I need to filter out the 'Private' entities.
However when I add a 'Where' clause to do this, the listener no longer adds newly posted entities from this collection. The first call to this function always has the 'listens' bool set to true, because it wants to listen for new entities posted/deleted by a user. I do not know why the events do not trigger the query.
Here is the current query code:

Answered 2020-Sep-15 at 01:21As suggested in the comments above, I created a composite index for the query in the Firebase console.
I will note that it was important to have the index structure a certain way. I tried creating an index with the following settings:
Collection ID : 'mags'
- Field 1: 'PublishedAt' : 'Descending'
- Field 2: 'Privacy' : 'Descending'
(note: firebase docs say to use either 'Ascending' or 'Descending' when you're using the 'in' clause even if you're not ordering on this field, it will not affect the equality of the query results)
This index did not work for some reason, I'm not sure why...
However, I realized other indexes created by a dev before me were mechanically similar but structured differently. So I mirrored that with the following:
Collection ID : 'mags'
- Field 1: 'Privacy' : 'Ascending'
- Field 2: 'PublishedAt' : 'Descending'
And it worked!
QUESTION
I'm trying to fetch data from Firebase using RxSwift. I'm using this to perform API calls.
So my db looks like this:
Collection Category (it has properties: title, about etc) has inside of it another collection called Manifests. To get Manifests I need to use documentId
of Category collection. So it's two different API calls but I want to combine results
That is what I have so far:
