I am developing an app in swift and using Firestore to store my data. It’s the first time that I am using Firebase.
Yesterday I connected the firebase and firestore to my project and everything worked fine. Today suddenly I got an error that It could not connect to the Firestore backend.
2020-04-03 13:37:25.851931+0200 Bouwresten[14277:2448929] 6.21.0 - [Firebase/Firestore][I-FST000001] Could not reach Cloud Firestore backend. Connection failed 1 time. Most recent error: Network connectivity changed This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.
Now I know for sure that my computer has a good connection and I am using the simulator of Xcode to test the app. Does anyone know what the problem could be?
This is my appdelegate.swift

import UIKit

import FirebaseFirestore
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FirebaseApp.configure()
return true
}
// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
}
This is the class where I use the firestore to get data, it's called dbhelper

class DBHelper
{
var Users = [User]()
var Products = [Product]()
init() {
getUsers()
}
func getUsers() {
Firestore.firestore().collection("Gebruikers").getDocuments() { (querySnapshot, err) in
if let err = err {
print("Error getting documents: \(err)")
} else {
for document in querySnapshot!.documents {
let user:User = User(Voornaam: document.get("Naam") as! String, Familienaam: document.get("Familienaam") as! String, Email: document.get("Email") as! String, Wachtwoord: document.get("Wachtwoord") as! String,
Stad: document.get("Stad") as! String, Postcode: document.get("Postcode") as! String, Straat: document.get("Straat") as! String, Nummer: document.get("Nummer") as! String, Added_on: document.get("Added_on") as! String)
self.Users.append(user)
print(self.Users.count)
}
}
}
}
func getProducts() {
Firestore.firestore().collection("Producten").getDocuments() { (querySnapshot, err) in
if let err = err {
print("Error getting documents: \(err)")
} else {
for document in querySnapshot!.documents {
let product:Product = Product(Titel: document.get("Titel") as! String, Beschrijving: document.get("Beschrijving") as! String, Prijs: document.get("Prijs") as! Double, Gereserveerd: document.get("Gereserveerd") as! Bool, Added_on: document.get("Added_on") as! String, Gebruiker_id: document.get("gebruiker_ID") as! String)
self.Products.append(product)
}
}
}
print(self.Products.count)
}
}
Hope someone can help me with this problem.
