Handle push notifications
When building an iOS app with XMTP, you might want to suppress certain Apple push notifications. For example, you should suppress push notifications for a user's own messages.
You can do this using the com.apple.developer.usernotifications.filtering entitlement.
To use this entitlement, you must first receive permission from Apple. To request permission, use the app owner's Apple developer account to submit this application: https://developer.apple.com/contact/request/notification-service.
Submit your application early
The approval process can take 2-3 weeks or longer.
Here are some sample answers to help you complete the application:
- App name: [Your app name]
- App Store URL: [Your app store URL]
- Apple ID of App: [Your app ID]
- App Type: Messaging
- Does your app provide end-to-end encryption? Yes
- Explain why existing APIs are not adequate for your app: The existing APIs always show some sort of notification when a push comes in. We don't want to show a notification for a user's own messages.
- Explain why your app doesn’t show a visible notification each time a push notification is received: The server delivering notifications only knows of the existence of a conversation. It does not know who the sender or recipient are. That data is decoded on the device in the extension. As a result, it sends a push notification for every message that occurs in the conversation. We want to filter out notifications for notifications that the user sent.
- When your extension runs, what system and network resources does it need? We might need to make a GRPC request in order to load additional information about a conversation. This is only necessary when we haven't stored the conversation details locally, which is expected to be less common than being able to just decode the conversation locally.
- How often does your extension run? What can trigger it to run? The extension will run whenever a message is sent or a received in a conversation. The frequency will depend on how active a user is.
