For a long time Apple Wallet has provided an API to create passes, be it coupons, boarding passes or event tickets.

The great thing about those is that you don’t need to pass a review to create them and you can distribute them as files!

But what does that have got to do with Notifications?

The interesting thing about those passes is that Apple provides a way to send Push Notifications when the passes get updated.

This is done so you can e.g. get notified when your flight gets cancelled/delayed.

This allows for a workaround for the above problem. What we want to do is this:

• Generate a pass for each of your users
• That pass has a single field that contains your notification text.
• When you want to send a notification to your users you simply update that field and your users receive a push notification!
