Я пытаюсь получить список данных из моей базы данных Firebase.Ниже мой код.Обе функции вызываются в моем viewDidLoad();, однако print(theLikeArray) возвращает пустые скобки, хотя моя база данных полностью заполнена.
Ниже приведен код, который я сейчас использую.Первая функция используется для получения всей информации из базы данных, а вторая - для заполнения базы данных.Вторая функция вызывается до первой.
func retriveDiscounts() {
let likesDB = Database.database().reference().child("Discounts")
likesDB.observe(.childAdded) { (snapshot) in
let snapshotValue = snapshot.value as! Dictionary<String , String>
let businessID = Int(snapshotValue["BusinessID"]!)
let businessName = snapshotValue["businessName"]!
let DateNumber = Int(snapshotValue["DateNumber"]!)
let theDeal = snapshotValue["theDeal"]!
let phoneNumber = snapshotValue["PhoneNumberText"]!
let imageName = snapshotValue["ImageName"]!
let dateText = snapshotValue["DateText"]!
let phoneNumberInteger = Int(snapshotValue["phoneNumberInteger"]!)
let companyLogo = snapshotValue["companyLogo"]!
let r1 = Int(snapshotValue["r1"]!)
let r2 = Int(snapshotValue["r2"]!)
let r3 = Int(snapshotValue["r3"]!)
let classification = snapshotValue["classification"]!
let allTheLikes = likeclass()
allTheLikes.discountID = businessID!
