I added support for the experimental push notifications feature. There are many improvements to be made, so this feature is currently opt-in only. If the user does not opt-in, their device tokens will not be sent out and thus they will receive no push notifications. We should perform more testing on real-life staging environments before fully releasing this feature. Testing ------- Testing was done gradually during development. Device: iOS simulators iOS: 17 Damus version: A few different but recent prototypes Rough coverage: 1. Checked that no device tokens are sent out when setting is off 2. Checked that I can successfully receive device tokens when feature is ON and set to localhost. 3. Checked sending test push notifications of types "note" (kind: 1), reaction (kind: 7) and DMs (kind 4) works and shows a generic but reasonable push notification message 4. Checked that clicking on the notifications above take the user to the correct screen Closes: https://github.com/damus-io/damus/issues/67 Changelog-Added: Add experimental push notification support Signed-off-by: Daniel D’Aquino <daniel@daquino.me> Signed-off-by: William Casarin <jb55@jb55.com>
