How can i fetch specific data from firebase and store it in a dictionary? - swift

Question

I'm trying to fetch data from my firebase database, such that i can store it in a form of dictionary which is a type [String: [Any]] where key is the unique id and the value is a type of array which has the data stored under uniqueID->Question.
func getData(currUser: String, completion: #escaping (([String : [Any]]) -> ())) {
var newArray = [String : [Any]]()
let ref = Database.database().reference(fromURL: "MYURL").child("users/\(currUser)/Questions").observeSingleEvent(of: .value, with: { (snap) in
let enumerator = snap.children
while let rest = enumerator.nextObject() as? DataSnapshot, let value = rest.value{
newArray.updateValue([value], forKey: rest.key)
}
completion(newArray)
})
}
this completion block gives me:
["-LlpbizBpQTXOQ6zv0zd": [{
Qusetion = (
Hello,
test,
kkkkkkkkkkk
);
}]]]
Instead how can i get
["-LlpbizBpQTXOQ6zv0zd": [Hello,test,kkkkkkkkkkk]]

You're converting the value to a string, while it's actually a JSON object. That's why the value in your dictionary is a JSON object.
To only get the question text under Qusetion (typo?), you'll need to loop over that child snapshot and collect the individual values. Something like:
var newArray = [String : [Any]]()
let ref = Database.database().reference(fromURL: "MYURL").child("users/\(currUser)/Questions").observeSingleEvent(of: .value, with: { (snap) in
let enumerator = snap.children
while let rest = enumerator.nextObject() as? DataSnapshot {
var values = [String]
let valueEnumerator = rest.childSnapshot(atPath: "Qusetion").children
while let valueRest = valueEnumerator.nextObject() as? DataSnapshot, let value = rest.value {
values.append(value)
}
newArray.updateValue([values], forKey: rest.key)
}
completion(newArray)
})
