I have an interesting issue. I am implementing Quick reply on my app. Basically, when the user gets a notification, he can answer from the notification (like iMessage or whatsapp)When the app is running or background, it works like a charm. But as soon as the app is being killed, the response will never be sent and the app won't be able to get any further notification. So to sum up, after the app killed, if the user receive one notification and answer to it, he will not be able to receive anymore notification until he lunches the app.
Any idea?
Thank you very much
EDIT: I found that when calling Handle Action the fonction RegisteredForRemoteNotifications was called. The problem was that the phone wasn't able to register the phone but It was succeeded when calling UnregisterAllAsync... So my phone wasn't registered anymore. Hope it helps! Cheers

I have an app in which I am using an FCM notification when there is an event from server.
I want to get the notification data and update the message from one of the parameter from Notification Payload when app is in background, foreground or killed.
I have tried to use Silent Push Notification with Content Available but when my app is killed, then I am unable to receive callback in my App delegate.
I have tried lots of links from StackOverflow but could not get the perfect suggestion.
If you find duplicate, then please provide me the link but solution with different iOS (12,13,14,15) versions.
My problem is just like this Stack Link
It sounds like what you want is a Notification Service Extension. This is a separate binary (packaged with your app) that can run when a notification is received. Your extension can intercept the push-notification payload, and modify it, so that other things can be displayed.

This is also really good, too.

I am working on an application which allows to send messages to another user.
If I press Home Button app goes first in background and then in suspended state so I don't receive any message unless I bring app back to the foreground.
How can I fix this to receive messages even if app is in background or suspended state? Solution is to avoid app to go suspended?
Some ideas please
Thanks and regards
For that you have to use Push notifications as they will wake your app when a notification is received (in your case a message is sent to your app). Do you have this implemented?
Another Dirty way would be to keep a silent Music file playing when in background state thus the app nevel sleeps (unless terminated by user). Nut keep in mind that this trick wont let you publish your app to the app store!
Hope this helps!
Use Voip to wake the app upon receiving push notification then handle it and pull from server as you want

Hey guys I did some searching online and didn't come up with much but I am looking to get all of the active notifications sent to my app since the last time I opened it. I found a lot of code with getting information from the notification the user opens the app with but that won't work since I want to be able to access all three notifications my app has instead of just the one I use to open it.
Now I was wondering if this was stored in a variable I can access from AppDelegate or if there is a delegate method I can add to AppDelegate that will be ran anytime a push notification is sent to my app even if my app has been killed and is not in the background.
Thanks for any help!
How does Whatsapp continue to receive notifications of received messages, even after you kill the app or restart the phone?
I am using an application that sends location coordinates, and it's for iOS, written in Swift.
My problem is that when I kill the app, the application stops sending coordinates. How I can make it restart automatically? For example, Whastapp, despite killing the app, if someone sends me a message, I receive the notification
I have also tried creating a widget app, but this is activated only when under the bar where the widget exists.
WhatsApp continues receiving PushNotifications. These are sent by Web Server and the App need not be active for it.
Coming to your requirement, you can use options like requestAlwaysAuthorization (to keep App awake in background to be able to send notifications). SignificantLocationChange, RegionMonitoringService, VisitService (to relaunch you app in the background if terminated).
Hope it helps.
Use this tutorial https://www.raywenderlich.com/123862/push-notifications-tutorial. you need to have one developer account to use push notification. It's easy to implement.
I am currently facing a problem with push notifications in iOS.
My app receives silent push notifications containing an identifier. This identifier is then used to fetch data from a remote server from which a local notification is created.
As far as I'm aware, if the user has force-quit an app (i.e. by double tapping the home button and swipe closing the app) then the silent push notification does not get passed onto the didReceiveRemoteNotification method in the AppDelegate class [1] [2], thus preventing the app from doing any kind of processing.
I have done a fair amount of research into handling the situation mentioned above. However, was unable to find a definitive answer and was hoping someone could help me out or point me in the right direction.
TLDR: What should I do when the user has force-quit my app, but I still need to process a silent notification?
Further Information:
My app only needs to support iOS8+.

The Notification Payload
If the target app isn’t running when the notification arrives, the alert message, sound, or badge value is played or shown. If the app is running, the system delivers the notification to the app delegate as an NSDictionary object.

Previously in iOS 7 and before, once a user force-quit an app, it will not be able to run and background tasks at all, including location monitoring, push notification handling with content-available:1 etc.
However the problem is that such behavior is not documented. The reason is that it may change in a new iOS update and Apple doesn't want to nail the coffin too early. As in iOS 8, PushKit is introduced and is supposed to be able to deal with the force-quit scenario. Please check this tutorial for details: https://zeropush.com/guide/guide-to-pushkit-and-voip
