How do I loop all Firebase children at once in the same loop?

Question

I have three nodes in firebase that I would like to loop through using the same loop. I\'m successfully able to loop through a single node (cookies) using this code:

You can convert snapshot to dict and loop through the dict:

databaseRef.child("cookies").observeSingleEvent(of: .value, with: { snapshot in
    if let dict = snapshot.value as? Dictionary> {
        for (key, value) in dict {
            if let recipeHeader = value["recipeHeaderFirebase"] as? String, favoriteArray.contains(key) {
                self.numberOfRecipes.append(recipeHeader)
             ...
            }
        }
    }
}

or you can use the enumerator:

databaseRef.child("cookies").observeSingleEvent(of: .value, with: { snapshot in
    let enumerator = snapshot.children
    while let (key, value) = enumerator.nextObject() as? FIRDataSnapshot {
        if let recipeHeader = value["recipeHeaderFirebase"] as? String, favoriteArray.contains(key) {
            self.numberOfRecipes.append(recipeHeader)
            ...
        }
    }
}
