This fake notification should be forwarded to firebase Swift5 iOS

Question

I have gone through the official notification and followed all steps. Also APN certificates are already uploaded on firebase. When i push notifciation from Grow section manually, i receive notification but while while entering phone number with country code in my app, i am getting the following errors.

This fake notification should be forwarded to Firebase Auth

Optional(Error Domain=FIRAuthErrorDomain Code=17054 "If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth's canHandleNotificaton: method." UserInfo={NSLocalizedDescription=If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth's canHandleNotificaton: method., FIRAuthErrorUserInfoNameKey=ERROR_NOTIFICATION_NOT_FORWARDED})

In Google info.plist, isfirebaseProxyEnable is also set to No.

DidreceiveRemoteNotification method also implemented.

Please help me in solving this problem.

To fix this, make sure you have this function in you AppDelegate file:

func application(_ application: UIApplication, didReceiveRemoteNotification notification: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    if Auth.auth().canHandleNotification(notification) {
        completionHandler(.noData)
        return
    }
}

It seems that you don't have APNs set up correctly, check that:

1. Push notifications is enabled in Capabilities of your app in Xcode settings.
2. Background Modes is enabled in Capabilities of your app in Xcode settings and under it Remote notifications is checked
3. Your app ID registered on apple developer site has Push Notification enabled
4. Background refresh is not disabled on the device or for your app in iOS Settings

I assume that you have an internet connection during the tests.

If any points of the above need to change, just delete the app completely from the device before re-compile and run it again.
