Firebase - Need to Read a Field From a Specific Collection and Document

I’m trying to use Cloud Firestore and I cant figure out how to read a specifc field. So I have the users name that I am trying to recall stored under
"users".email.firstName , firstName being the field. I have the email stored in the email variable and that being said, is it possible to recall the specific string in the firstName field?

Hi Reece,

Have followed the PhotoApp tutorial in the iOS Database course? The process of creating and retrieving records from Firestore is pretty well explained there.

Can you provide a screenshot of your Cloud Firestore “user” record so that we can see the collection layout.
