title: Strategy for Push notifications on Safari
body: <p>I am working on implementing a PWA which needs to send push notifications, we are looking at a solution for sending push notifications to browsers running on ios(We are using Firebase(FCM) for everything else.) What would be a good strategy to make push notifications on all platforms including ios?</p>
  
  <p>We are looking at sniffing the user-agent and use FCM for non-ios users, switch to websockets for ios users. We aren't sure how viable this approach is gonna be. Any suggestions on this approach or a better alternative would be of great help!    </p>
