A possible option would be to query your documents and retrieve a specifc OwnerID like this. If you want to fetch all OwnerIDs from all of your documents just remove the 'whereField'.

Also check out the Firebase documentation for queries.

   let docRef = db.collection("YOURCOLLECTIONNAME")
   let query = docRef.whereField("OwnerID", isEqualTo:"VAL")

    query.getDocuments{ (querySnapshot, error) in
         if let error = error {
            print("\(error.localizedDescription)")
         }else {


              for documents in (querySnapshot?.documents)! {

                   if let owner = documents.get("OWnerID") as? String {
                      print(owner)
                    }
    }
