I am making a tinder type app, at the moment I have cardViewModels: [CardViewModel] which contains 4 fictitious app users in the producers array of user objects.
this currently works fine and loads the user on to the tinder type cards.

though now I would like to some how replace the fictitious users with other fictitious users from Firebase/Firestore.

I would expect to call fetchUsersCurrentUserIsFollowing() which returns
UserGrapevine users (as seen below)

UserGrapevine(name: displayName, age: age, profession: occupation, imageNames: ["lady5c"], kmsAway: distanceInKms)

I then wish to append these users to the producers array and then call setupDummyCards() after my producers array has been set with the users from Firestore?

    let cardViewModels: [CardViewModel] = {



    let producers = [

        UserTinder(name: "Kelly", age: 23, profession: "Music DJ", imageNames: ["lady5c","lady4c","kelly1","kelly2","kelly3"]),

        UserTinder(name: "Jane", age: 18, profession: "Teacher", imageNames: ["jane1","jane2","jane3"]),

        Advertiser(title: "Buy My Shirt", brandName: "Ben's Shirts", posterPhotoName: "lady5c"), Joker(title: "JOKER", cardSuit: "HEART", jokerPhotoName: "lady5c")] as [ProducesCardViewModel]





  let viewModels = producers.map({return $0.toCardViewModel()})





    return viewModels



}()





    fileprivate func setupDummyCards() {

    cardViewModels.forEach { (cardVM) in

        let cardView = CardView(frame: .zero)

        cardView.cardViewModel = cardVM

        cardsDeckView.addSubview(cardView)

        cardView.fillSuperview()

    } 

}









  func fetchUsersCurrentUserIsFollowing(){



    guard let uid = Auth.auth().currentUser?.uid else { return }



    let db = Firestore.firestore()



    db.collection("Users").document(uid).collection("Following").getDocuments() { (querySnapshot, err) in

        if let err = err {

            print("Error getting documents: (err)")

        } else {

            for document in querySnapshot!.documents {

                //print("(document.documentID) => (document.data())")



                let d = document.data()



                d.forEach({ (key: String, value: Any) in

                    print("this is the key",key)





                    Database.firestorefetchUserForGrapevineCardWithUID(uid: key, completion: { (user) in





   //append to producers list somehow.



                    }
