Web Push Notifications
With iOS 16, Apple promised to expand the ability for websites to send push notifications to iOS and iPadOS for the first time. While the announcement was met with quite a bit of enthusiasm by web developers, it seems to have been on the back burner since then.
Web push notifications have been available through Safari in macOS for several years now, so it’s logical to expand that to the mobile version of Safari. Apple says it still has plans to release this sometime in 2023 but likely wants to make sure this is handled in the most non-invasive way possible.
