There doesn't seem to be a What's New in Networking or What's New in Foundation talk this year, and nothing mentioned in the various Release Notes, so can you summarize the overall changes across platforms, or point to a document that does so?

For many months now we've been building a watchOS app with push support. On device, these usually work fine, but in the sim, only loud pushes are ever received (don't contain content-available). This includes pushes triggered from our backend, whether directly or through Firebase Cloud Messaging, from Apple push web interface, from apns files dropped onto the sim, or from files sent using simctl push. All say they were sent successfully, none trigger any of the push related WKApplicationDelegate methods. As I understand it, only didReceiveRemoteNotification should be triggered for this kind of push. Additionally, can anyone confirm what the proper background mode setup is for push notifications on watchOS? Is it supposed to remote-notification under UIBackgroundModes or WKBackgroundModes? For WKBackgroundModes Xcode only offers a few watch specific values, but not the push value. The docs are unclear on this part.
