@dipak10112 Did you set the apns-push-type header field to alert when you send the notification to the APNS server?

I am in the same situation, I can confirm the type is set to alert but still unable to filter the notification

Received remote notification request 8B7E-2E97 [ waking: 0, hasAlertContent: 1, hasSound: 0 hasBadge: 0 hasContentAvailable: 0 hasMutableContent: 1 pushType: Alert]

After my extension returns an empty UNNotificationContent, I see this in console:

Mutated notification request will not visibly alert the user, will deliver original content; notificationRequest=8B7E-2E97, runtime: 9.882166

Then it delivered the visible notification:

Saving notification 8B7E-2E97: 1 [ hasAlertContent: 1, shouldPresentAlert: 1 ] Delivered user visible push notification 8B7E-2E97

Hi,

There is a note on the documentation about this:

To silence a remote notification, you must set the apns-push-type header field to alert when you send the notification to the APNS server. Otherwise, the system always displays the notification banner to the user.

Does this work in sandbox environment? I think I got everything setup based on the doc but on sandbox I cannot silent the notification. I do have the push type header set but on console I still see the should present = 1

I read thru the open source Signal Messenger code, they only have the filtering entitlement for App Store, so I am wondering if this only works for App Store (production push)?

Hi. I am facing same problem, I got access to use entitlement but notification is not being hidden. I tried it with both sandbox and production env. My notification payload is

[AnyHashable("aps"): { alert = { body = "Tap to explore"; title = APP Name; }; badge = 0; "content-available" = 1; "mutable-content" = 1; }]

As described here com.apple.developer.usernotifications.filtering you have to use an extension and then to call contentHandler(UNNotificationContent()) to suppress a notification. As for the APS-Payload "mutable-content" has to be set and it has to be an alert. Without "mutable-content" your notification is not being called.

Hello I have the same problem The model of my notification is

{
  "headers": {
     "apns-push-type": "alert"
  },

  "aps": {
	"alert": {
			"title": "Test title",
			"body": "You have received a new message."
	},
	"mutable-content": 1
  }
}

I can catch notification in UNNotificationServiceExtension but i can't filter it with contentHandler(UNNotificationContent())
