Capacitor: Failed to setup push Notifications for iOS

[SergeyMell]

I followed the steps described in
https://capacitor.ionicframework.com/docs/guides/push-notifications-firebase/

According to recommendations, I've changed my didRegisterForRemoteNotificationsWithDeviceToken code in AppDelegate.swift as follows:

  func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    // NotificationCenter.default.post(name: Notification.Name(CAPNotifications.DidRegisterForRemoteNotificationsWithDeviceToken.name()), object: deviceToken)

    Messaging.messaging().apnsToken = deviceToken
    InstanceID.instanceID().instanceID { (result, error) in
        if let error = error {
            NotificationCenter.default.post(name: Notification.Name(CAPNotifications.DidFailToRegisterForRemoteNotificationsWithError.name()), object: error)
        } else if let result = result {
            NotificationCenter.default.post(name: Notification.Name(CAPNotifications.DidRegisterForRemoteNotificationsWithDeviceToken.name()), object: result.token)
        }
    }
  }

However, I'm getting an error

Static member 'instanceID' cannot be used on instance of type 'InstanceID'

Could I get any help on this?

I just followed the tutorial the other day and didn't face this problem.
Can you provide a sample app?

I just made a few changes the other day, needed for Capacitor 2.0, but they are not published yet, you can check the file that generates the docs here
https://github.com/ionic-team/capacitor/blob/master/site/docs-md/guides/push-notifications-firebase.md

1. Actually, when I followed the tutorial I faced an issue even in this place

PushNotifications.requestPermission().then( result => {
      if (result.granted) {
        // Register with Apple / Google to receive push via APNS/FCM
        PushNotifications.register();
      } else {
        // Show some error
      }
    });

Because PushNotifications.requestPermission method does not exist and I had to move to PushNotifications.register(); directly but anycase this seems to be overcamed

1. I've invited you to a private repository with a project so you could take a look.

Thanks in advance for your help
Looking forward to hearing from you soon.

Capacitor 2.0 is still in beta, you can install it using next tag
i.e.
npm install @capacitor/ios@next
(Also for core and cli)

You have not committed ios folder, that's what I'm interested in

[SergeyMell]

So all these instructions are for capacitor 2.0? Not for 1.5?
However, anycase my problem (as I understand) is related to AppDelegate.swift and Firebase pod. This should not relate to capacitor I think

iOS folder also pushed to the project now

[jcesarmobile]

The requestPermission method is new in Capacitor 2.0, the other things didn't change.
I thought latest doc changes weren't published, but I had a cached version.

ok, any case, this is not critical for now

This error:

Static member 'instanceID' cannot be used on instance of type 'InstanceID'

in AppDelegate.swift looks much more important

Your problem is you have phonegap-plugin-push installed, that is using a very old version of Firebase Messaging (2.x, while latest is 4.x).
So uninstall the plugin and run npx cap sync ios

Thanks a ton! It built successfully
Appreciate your help
