I can get the notification by calling didReceiveRemoteNotification , but if the App is running in background and there are 5 notifications, how to get all notifications when App become active?
Unfortunately, there is no way to do this. The data from a notification can only be pushed by clicking the individual notification. More info here: iOS Push Notification - How to get the notification data when you click on the app icon instead of notification

I have subscribed to APNS notifications in my Swift iOS app.
I am only interested in user-facing notifications, so i have not setup a background mode.
If the app is open, the UNUserNotificationCenterDelegate's userNotificationCenter:willPresent:withCompletionHandler is called. If the app is in the background AND the user taps on the notification (which opens my app by default) userNotificationCenter: didReceive: withCompletionHandler is called.
However, if the user simply dismisses the notification in the notification center, then my app doesn't know that the notification was delivered.
Is it possible to somehow inspect which notifications were delivered when app was in the background or killed and that user hasn't tapped on, upon app launch?
Do you control the payload of the notification?
If you can put 'mutable-content' in the aps dictionary you can use a UNNotificationServiceExtension.
The extension will get notified before a notification is displayed.
You don't have to edit the notification but you'll be able to save any info about it that you want.
I'm creating an App with xamarin using notification hub for the notification
When the app is in foreground i'm able to process the notification with my implementation of UNUserNotificationCenterDelegate in the WillPresentNotification method and displaying correct title and other data
While when the app is in backgorund or inactive the notification is displayed without passing through any method, so i can't format it
I already tried to add "content-available" as a parameter and what happend was that the plain notification, not formatted correctly is first displayed, then DidReceiveRemoteNotification is fired and another notification, with the correct format is displayed
iOS handles notifications differently depending on if your app is in the foreground or background.
App in foreground:
runs through DidReceiveRemoteNotification.
App in background:
does not immediately run through DidReceiveRemoteNotification. The OS generates and displays the notification. Upon selecting the notification, the app will run through DidReceiveRemoteNotification.
see documentation
I already can manage push notifications from FCM when the app is in Foreground or background, when I do click in notification popup and open app "application didReceiveRemoteNotification" work without problem
My problem is that i don't know how get notification push data if the user open the app normaly (do click in icon app instead of click in notification) and I would lost the data if he close the notification
If the app is in background state UINotification called application didReceiveRemoteNotification , If app is in open state UINotification called application:didFinishLaunchingWithOptions, And can't possible to get data without click on notification in iOS.
check
UIApplicationLaunchOptionsRemoteNotificationKey
or
application:didFinishLaunchingWithOptions
My app is receiving a notification and my problem is that when I received one or more notifications in the background and when i click the app icon to bring me in my app foreground then the notification message(s) doesn't able to display in the foreground it will only works if I click the pop up message in notification center not the icon.
You will not get remote push notification data on launch of app after tapping icon. You can only parse push notification body only on tap of notification alert.
So if you want to do any MUST NEED operation for such notifications there is only way is to introduce server in between. So you can use any web service for it and this will be called every time your app launches or comes to foreground. Call that API on background and do the needful you want.
I'm having a little problem in my app : I use to send local notifications to the user when actions are performed in my app, while it's running in background. Notifications are displayed perfectly in the notification center, but there is no pop-up when the notification occurs.
If I'm right, apps running in foreground can't display pop-up on the user screen (only in the notification center) but when the app is running in background, in fact there is pop-up displayed automatically ?
Thanks for your help !
EDIT : In fact, I'm speaking about a notification banner to be displayed too when the notification appear in the notification center.
When your app will go in background then you will see an immediate notification on your phone but you have to tap that notification to trigger didReceiveLocalNotification delegate.
If you receive local notification in foreground then didReceiveLocalNotification will be triggered automatically.
Above scenario is tested and verified.
