swift firestore appending users to array - completion block












1















I am trying to call the function self.setupDummyCards() after self.cardViewModels.append(user.toCardViewModel()) has finished appending all users to CardViewModels Array though i can't figure out where to put it?



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


Firestore.firestore().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 {
let d = document.data()
d.forEach({ (key: String, value: Any) in



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

self.cardViewModels.append(user.toCardViewModel())

//below it is called after each user is appended, meaning it appends the same users again and again until the last user is add
self.setupDummyCards()
})
//here is called before self.cardViewModels.append(user.toCardViewModel())
})

//here is called before self.cardViewModels.append(user.toCardViewModel())

}
//here is called before self.cardViewModels.append(user.toCardViewModel())
}
//here is called before self.cardViewModels.append(user.toCardViewModel())
}
//here is called before self.cardViewModels.append(user.toCardViewModel())
}
