Rough notes on Remote Notifications (i.e. sent from firebase server/ console > Notifications, not Local Notifications):

1. New single page app - Select project -> Target capabilities -> Select ON for Background modes(check remote) and push notifications

2. pod init

   pod 'Firebase/Core'
   pod 'Firebase/Messaging'

then pod install
