Your code creates a query, but doesn't execute it. So that means you're printing the query itself, not its results.

If you have a look at the documentation on getting documents from the database, you'll find this Swift example of how to do so:

db.collection("cities").whereField("capital", isEqualTo: true)
    .getDocuments() { (querySnapshot, err) in
        if let err = err {
            print("Error getting documents: \(err)")
        } else {
            for document in querySnapshot!.documents {
                print("\(document.documentID) => \(document.data())")
            }
        }
}

You're going to want to call getDocuments() on your query in the same way and process the results you get.
