Read array from firebase once and put it into an array

How to read firebase array and put it into swift array? I'm trying to solve this problem for like 4 hours. What am I doing wrong?

enter image description here

ref.child("names").child("myNames").observe(.value) { (snapshot) in
        if let item = snapshot.value as? String {
            namesArray.append(item)
        }
    }

You should parse the snapshot as [String : Any]? and fetch the values in the dictionary.

ref.child("names").child("myNames").observe(.value) { (snapshot) in
    if let itemDictionary = snapshot.value as? [String : Any] {
        for (key, value) in itemDictionary {

            // Another check for String
            if let valueString = value as? String {
                namesArray.append(valueString)
            } 
        }
    }
}

You are trying to unwrap an array of String as a single String, so that is why it's failing. Change to the following:

ref.child("names").child("myNames").observe(.value) { (snapshot) in
    if let item = snapshot.value as? [String] {
        namesArray = item
    }
}
