UNNotificationServiceExtension:

  • It has no user interface, so less control over this. Just limited functionality
  • It has excellent background mode. First, it prepares himself then displays the user.

UNNotificationContentExtension:

  • It has a user interface, You can customize your desired.
  • Its instantly displays. and content download starts after displaying.

First of all they are different objects:

  • UNNotificationServiceExtension - is an class. It's "lets you customize the content of a remote notification before it is delivered to the user". For example, you could use the extension to decrypt an encrypted data block or to download images associated with the notification.
    So you don't change the UI of Notification, but you can modify notification content.
  • UNNotificationContentExtension - is an protocol. "You adopt this protocol in the custom UIViewController subclass that you use to present your interface."
    So you can create custom interface for your notification (ex. for some type of notification) and add your controls.
