            }
        }
    }
    
    class AppDelegate: NSObject, UIApplicationDelegate {
        func applicationDidFinishLaunching(_ application: UIApplication) {
            Task {
                let isPushNotificationAllowed = await AmplifyUtilsNotifications.AUNotificationPermissions.allowed
                // ...
            }
        }
    }

  4. Open up *.xcworkspace with Xcode, and you will be able to use the AmplifyUtilsNotifications package in your project.

Notification Service Extension for AWS Pinpoint

This package includes a ready to use implementation(AUNotificationService) for handling remote notifications sent by AWS Pinpoint. It helps with decoding notification json data and retrieving the remote media url as an attachment.

Push notification in AWS Pinpoint format

  1. Add a Service App Extension to Your Project. Apple Doc.

    add-notification-service-extension

  2. Update info.plist of the newly created Notification Service Extension.

    <dict>
        <key>NSExtension</key>
        <dict>
            <key>NSExtensionPointIdentifier</key>
            <string>com.apple.usernotifications.service</string>
            <key>NSExtensionPrincipalClass</key>
            <string>AmplifyUtilsNotifications.AUNotificationService</string>
        </dict>
    </dict>

    Note:

    We suggest you either keep the auto generated NotificationService.swift source file or add an empty swift file for your Notification Service Extension target. An empty source list will cause an error when you try to install the extension to a real device.

Push notification not in AWS Pinpoint format

You can also subclass AUNotificationService to support a different notification payload format or add custom functionality.

For example, we want to send the push notification with a field name video_url.

  1. Define a MyPayload struct that conforms to the AUNotificationPayload protocol. It defines the remoteMediaURL.

  2. Subclass AUNotificationService and change the payloadSchema property to MyPayload that was defined in the previous step.

    import AmplifyUtilsNotifications
    
    struct MyPayload: AUNotificationPayload {
        var remoteMediaURL: String? {
            video_url
        }
    
        let video_url: String
    }
    
    class NotificationService: AUNotificationService {
    
        override init() {
            super.init()
            self.payloadSchema = MyPayload.self
        }
    }
  3. Update the info.plist by setting NSExtensionPrincipalClass to $(PRODUCT_MODULE_NAME).NotificationService.

You can also override the didReceive function to modify the content as desired. For example, attach suffix [MODIFIED] to your notification title.

override func didReceive(
    _ request: UNNotificationRequest,
    withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void
) {
    super.didReceive(request) { content in
        self.contentHandler = contentHandler
        let mutableContent = content.mutableCopy() as? UNMutableNotificationContent
        mutableContent?.title = content.title + "[MODIFIED]"
        if let mutableContent {
            contentHandler(mutableContent)
        }
    }
}
