Firebase retrieve data below auto ID In Swift

Question

I\'m in trouble in retrieving data from Firebase.

I\'d like to read all contactName data in JSON under auto ID , then append to UIPickerView.

Here is my JSO

Answer 1

I solved myself!

But first of all, I decided not to use UIPickerView.

And what I wanna do is to add data below auto ID.

I'm not sure this is good algorithm for solving this problem, But Anyway, I made it :)

dbRef.child("user/contacts/").observe(.value, with: {(snapshot) in

    if let result = snapshot.children.allObjects as? [DataSnapshot] {

            for child in result {

                let orderID = child.key as String //get autoID

                self.dbRef.child("user/contacts/\(orderID)/contactName").observe(.value, with: { (snapshot) in

                    if let nameDB = snapshot.value as? String {

                        if self.debtorName == nameDB {

                            self.dbRef.child("user/contacts/\(orderID)").updateChildValues(data)
                        }
                    }
                })
            }
        }
    })
