I’ve hooked up the code under, please let me know the place is the issue.
I’ve additionally hooked up firebase database screenshots for each earlier than and after iteration.
static func joinCommettie(params: dictionaryParameter, _ committeeID: Int, completion: @escaping(_ standing:Bool, _ message: String)-> Void) {
ref = Database.database().reference(withPath: International.shared.COMMITTEES)
ref.queryOrdered(byChild: "joinningCode").queryEqual(toValue: committeeID).observeSingleEvent(of: .worth) { (snap) in
print(snap)
if snap.exists() {
print("-------Commettie Knowledge exists--------")
if let dict = snap.worth as? [String: Any] {
if let id = dict["id"] as? String {
ref.baby(id).baby("members").childByAutoId().setValue(params) {
(error:Error?, ref:DatabaseReference) in
if let error = error {
print("Knowledge couldn't be saved: (error).")
completion(false,error.localizedDescription)
} else {
print("Knowledge saved efficiently!")
