SwiftUI swizzling disabled by default, phone auth not working - swift

Question

I am building a screen with phone number login. I checked over and over again and the project is newly created, however, I am getting this log:
7.2.0 - [Firebase/Auth][I-AUT000015] The UIApplicationDelegate must handle remote notification for phone number authentication to work.
If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth's canHandleNotificaton: method.
I did read in the documentation about swizzling and I don't know why it seems to be disabled, I did not disabled it. I have added GoogleServices-Info.plist into the app, I added in firebase panel the app apn auth key.
My entry point in the app looks like this:
#main
struct partidulverdeApp: App {
init() {
FirebaseApp.configure()
}
var body: some Scene {
WindowGroup {
MainView()
.onOpenURL { url in
Auth.auth().canHandle(url.absoluteURL)
}
}
}
}
My URL Types property has an entry with the RESERVED_CLIENT_ID
I am very desperate about this problem. Any idea is highly appreciated.
Edit1:
I did read the documentation and tried to handle notification with swizzling disabled, but I get the same error:
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication,
didReceiveRemoteNotification notification: [AnyHashable : Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
if Auth.auth().canHandleNotification(notification) {
completionHandler(.noData)
return
}
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
print("Your code here")
return true
}
}
#main
struct partidulverdeApp: App {
#UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
init() {
FirebaseApp.configure()
}
var body: some Scene {
WindowGroup {
MainView()
.onOpenURL { url in
Auth.auth().canHandle(url.absoluteURL)
}
}
}
}

Here's how to implement Phone Number Auth using the new SwiftUI 2 life cycle:
Create a Firebase project and set up PhoneNumber Auth
Add your iOS app to the Firebase project, download and add GoogleService-Info.plist to your project
In Xcode, select the application target and enable the following capabilities:
Push notifications
Background modes > Remote notifications
Create and register an APNS authentication key on the Apple developer portal
Upload the key to Firebase (under Project Settings > Cloud messaging in the Firebase Console)
Add the Firebase project's reversed client ID to your app's URL schemes
In your Info.plist, set FirebaseAppDelegateProxyEnabled to NO
Implement the AppDelegate as follows:
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
FirebaseApp.configure()
print("SwiftUI_2_Lifecycle_PhoneNumber_AuthApp application is starting up. ApplicationDelegate didFinishLaunchingWithOptions.")
return true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
print("\(#function)")
Auth.auth().setAPNSToken(deviceToken, type: .sandbox)
}
func application(_ application: UIApplication, didReceiveRemoteNotification notification: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
print("\(#function)")
if Auth.auth().canHandleNotification(notification) {
completionHandler(.noData)
return
}
}
func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
print("\(#function)")
if Auth.auth().canHandle(url) {
return true
}
return false
}
}
#main
struct SwiftUI_2_Lifecycle_PhoneNumber_AuthApp: App {
#UIApplicationDelegateAdaptor(AppDelegate.self) var delegate
var body: some Scene {
WindowGroup {
ContentView()
.onOpenURL { url in
print("Received URL: \(url)")
Auth.auth().canHandle(url) // <- just for information purposes
}
}
}
}
