apns | Go package to interface with the Apple Push Notification | Notification library

I have an Ionic 5 angular app with push notifications, using the @capacitor/push-notifications plugin. Set up correctly as described here, and running on iOS.

PushNotificationService:

Using CAPACITOR and IONIC Everything is Perfectly Works on Android but in IOS i am having Following Error:

APNS device token not set before retrieving FCM Token for Sender ID 'mySenderId'. Notifications to this FCM Token will not be delivered over APNS.Be sure to re-retrieve the FCM token once the APNS device token is set.

My application is live on apple store. I need to add push notifications in my app. I have done all the required steps but when I am trying to upload ,.p12 certificate in APNS Certificate upload section in firebase console then I am getting the error message.

You can see in snapshots.

I use airplay to test, demo and develop an iOS device, especially using push notifications. This is because although you can drag .apns files onto a simulator, simulators don't work with APNs.

In iOS 15, they've made macOS devices running Monterey able to connect as an Airplay receiver. You can show your iOS screen on macOS using Airplay. (previously you needed AirServer). However, now all push notifications seem to be hidden when airplay is being used.

When looking at the Console.app:

This code with a smaller list of tokens works correctly, but I don't know why it fails to send the notification to all the tokens when individually the token is valid.

I am doing something wrong? when the token list contains fewer tokens, all notifications are sent. There is a maximum of 30 tokens.

Preface:

My App is Flutter based - but native code implementation is required to get FCM messages working, see below for more details

GitHub issue #154 for reference.

I'm having immense trouble getting FCM notifications working on iOS, specifically on my app published to Testflight. I have been stuck on this problem for a week and have absolutely no idea how to proceed.

Problem

When running locally using debug/release builds on my devices using Xcode/Android Studio, notifications are received in the background, foreground, etc. When uploading the exact same app to Testflight, not a single notification will come through via FCM.

This is crucial as FCM delivers VoIP notifications, these aren't being received on Testflight which is extremely distressing

Questions & Solutions?

There are 2 questions I found (here & here), both seemed to indicate it is a APNS certificate problem (APNS -> Firebase). I have recreated my certificate and added it to the Firebase console (using the same .csr file for all certificate generating operations)

Setup/Configuration:

• APNS Key generated & added to Firebase

• Capabilities:

Tried with:

A project I'm working on requires the use of FCM Push Notifications & Messages for VoIP control amongst others.

Problem:

My iOS physical device receives push notifications, but only when the app is in the background or closed but NOT when in the foreground. Further, it does NOT receive any fcm message (data) notifications at all such as messages with only data and no notification title/body i.e. VoIP status message.

My setup steps are as follows (a detailed setup and general flow I followed can be found here):

1. Register a (Info.plist) (see here)

2. Download & install GoogleService-Info.plist with Xcode (see here)

3. Create APNS key with enabled Push Notifications and uploaded .p8 file to Firebase (see here)

4. Modify with Swift code:

AppDelegate.swift code:

Background: The Polkadot App's frontend allows us to call claimer.lookuplink without any options. This returns a list of APNs and the associated accounts. The substrate-frontend-template that we have been building off of requires that we include an option, which does not allow us to get all APNs and accounts. As a workaround we have tried to make a direct RPC call, but we cannot figure out how to decode the response.

I believe the response is SCALE encoded. Below is a blog post discussing some of the intricacies of doing this: https://www.shawntabrizi.com/substrate/querying-substrate-storage-via-rpc/

For the specifics of what we are currently trying you can look in this file: https://github.com/Greenetwork/BLX_frontend_new/blob/maprefresh/src/MapRefresh.js#L21 The response to getKeysPaged call is being decoded by the Polkadot frontend, but I haven't found a way to decode it in our https://github.com/Greenetwork/BLX_frontend_new

I am using the react-native-firebase library.

On iOS, I am able to receive notifications in the foreground, background and also when the app is in quit state. Handlers work in every scenario too, except for one.

My only problem is: setBackgroundMessageHandler is not being invoked when the app is in quit state, even though I am receiving the notification. I also tried to send data-only messages but the result was the same.

I am even able to invoke the app in a headless state using content-available: 1 in the message's apns section.

But still the setBackgroundMessageHandler is not getting invoked. This is my index.js page:
