In iOS 15.4, Apple is likely to add an interesting feature to Safari. It would become possible to enable push notifications for web apps.
iOS 15.4: Push Notifications Web Apps Safari
According to developer Maximiliano Firtman, Apple has laid the groundwork for allowing Safari push notifications in iOS and iPadOS. This has been possible in Safari on the Mac for years, but now it looks like the feature is also coming to Apple’s mobile devices.
Firtman discovered the option in the beta (trial) version of iOS 15.4. WebKit (Safari’s browser-only) features two new switches: “Built-in Web Notifications” and “Push API.” They’re disabled by default and don’t work yet, but it’s a hint that Apple is working on a new push notification API for iOS and iPadOS.
Notifications from Safari
Enabling notifications will likely work in the same way as Safari for macOS. Sites may pop up asking you to allow push notifications. Your choices are then saved in a special tab. You can probably find it in the Settings app under Safari. Web app notifications may also be supported in other browsers, such as Chrome and Firefox.
Furthermore, the developer noticed that the beta version of iOS 15.4 includes the WebXR API, which provides support for augmented and virtual reality headsets on websites. This is striking, as there are currently no AR or VR headsets that work with iOS. It’s new evidence that Apple’s first mixed reality headset is on the way, expected in late 2022.
The official release of iOS 15.4 is expected in the spring. It’s a major interim update, with a lot of new features. You can read what those are in this article:
