swift firestore appending users to array - completion block
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())

i just got documents.count and then only called the self.setupDummyCards() once documents.count was equal to cardViewModels.count
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 {
let dc = querySnapshot?.documents.count
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())
if self.cardViewModels.count == dc {
self.setupDummyCards()
}
})
})
}
