Hello!

I am working on an app that requires to send a local push notification to the user from an app extension (from the ShieldActionDelegate to be precise).

This is suggested by DTS as a workaround for this issue: https://forums.developer.apple.com/forums/thread/766644

But now, on the iOS 18.2 beta, local push notifications are delayed by up to 10 seconds, even though the push notification is classified as .timeSensitive, leading to a very bad user experience (where to user has to sit and wait for the notification to arrive without knowing how long it will take).

This only happens when Apple Intelligence is turned on.

This had happened previously on the iOS 18.1 beta but was fixed for the final release: https://forums.developer.apple.com/forums/thread/764848

But now the issue came back on the latest iOS 18.2 beta.

I have documented the new behavior in FB15668616

Any help is appreciated!

Hi Quappi,

The issue was never resolved in 18.1. I read your other thread but I think it was a fluke that it disappeared for you. There’s many posts stating it still existed.

My feedback ID FB15317688 has over 10 cases associated with resolution still open.

I had to turn off AI as the delay was interrupting my business related work. What a shame!

Thank you all for your Feedback reports on this. We are still evaluating the impact.

If you have not done so already, please make sure to include details about your notifications implementation for your app. Local vs. push, using notification extensions, processing background notifications, how you are handling the notifications if the app is running in the foreground, etc.
