Does the new iOS 12 safari support web push notification with service worker? In the last version of iOS there was service worker but there wasn't the pushManager object.
回答1:
iOS 12 and 13 still doesn't support these features:
- Web Push Notification
- Background Sync
- Page Lifecycle
- Service Workers on WebViews
- Universal Links / Link Capturing
I think iOS doesn't want to support these in PWA because these features have a bigger chance to be unnecessary exploited(spam, etc). And also maybe they want to force developers to create the native application rather than the progressive web application.
回答2:
iOS don't support the W3C Spec web push notifications yet. But there is a Safari specific API for web notifications. Refer to this answer on multiple options you have.

Update: Corrected the Answer in the above link to clarify proprietary solution is only for OS X - Safari and no solution for iOS Safari yet. Custom in app notification is the best we can do today for iOS Safari.

I tested iOS 12 in beta last week and as Anand said, there is no change about this functionnality and more globally for Progressive Web App because the Web Manifest, in developpement at this moment is not implemented yet.
