iOS 11.3/16.4版本Web Push在PWA中的支持情况问询

Hey there! Let's break down everything you need to know about Web Push support in iOS 16.4 for PWAs, plus updates on OneSignal compatibility—since you’ve been keeping an eye on this since iOS 11.3 rolled out Service Workers, I’m glad we finally have some concrete news!

Current Web Push Support Status in iOS 16.4 #

• iOS 16.4 marked a big milestone: it officially added Web Push notification support for PWAs! This fills a long-standing gap since Service Workers were first introduced.
• To get Web Push working for your PWA on iOS 16.4+, you’ll need to meet these requirements:
  • Your PWA is added to the user’s home screen
  • Your site uses HTTPS (localhost is allowed for local development)
  • You’ve properly configured your Service Worker and implemented the Push API as specified in web standards

OneSignal Compatibility Update #

• Great news: OneSignal has rolled out updates to support iOS 16.4’s Web Push for PWAs! Make sure you’re using the latest stable version of the OneSignal SDK—check their release notes to confirm you have the compatible build.
• Since you already have it working smoothly on browsers and Android, the transition to iOS should be straightforward once you update the SDK. Just note that iOS has a slightly different user flow: users must first add the PWA to their home screen before they’ll see the push notification authorization prompt.

Reliable Channels to Stay Updated #

• Apple’s official developer documentation: Keep an eye on Safari and PWA-related release logs for detailed specs, configuration steps, and any future changes to Web Push support.
• OneSignal’s official announcements: They post real-time updates about platform compatibility, including step-by-step guides for setting up iOS 16.4 Web Push.
• Apple Developer Forums: Connect with other developers to troubleshoot specific issues, share workarounds, and learn from real-world implementation experiences.
