How to Implement Push Notifications in iOS Apps (Swift, JWT Token Method)
There are two authentication methods for sending Push Notifications to iOS apps via APNs (Apple Push Notification service): the certificate-based method and the token-based method.
Previously, in How to Implement Push Notifications, we explained the certificate-based method.
While the certificate-based method is still supported, Apple now recommends the token-based approach. In this guide, we’ll explain how to implement Push Notifications using the token-based method (JWT authentication).
Only steps 3 and 5 differ from the previous tutorial; the other steps remain the same, so we will link back to the earlier articles where appropriate.
To implement Push Notifications in an iOS app, you must be enrolled in the paid Apple Developer Program. For details, see About the Apple Developer Program.
Now, let’s walk through how to implement Push Notifications using the JWT token authentication method.
