Description
This is a sort of sibling issue to #3150 -- in addition to using a distinct, recognizable sound, I'd like to use a distinct, recognizable vibration pattern. This is for basically the same reason as the OP of #3150 explained there:
so I can tell without looking at my phone what's asking for my attention.
Chat discussion here with details.
Unlike with sounds, it looks like there isn't an API for us to be able to do this on iOS. I don't see any reference to vibration either in the APIs we'll get to use when we write client-side code to control notifications:
https://developer.apple.com/documentation/usernotifications/unmutablenotificationcontent
or in the API we're currently using, specifying the details from the server side:
https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/generating_a_remote_notification#2943363
So this is an Android-only issue without an iOS counterpart.
