Struggling with Push Notifications in Swift 5? Here's How to Fix It!

Having trouble receiving push notifications in your iOS app using Swift 5 and Firebase Cloud Messaging (FCM)? You're not alone! Many developers face this challenge while trying to integrate FCM for real-time communication features, like incoming calls or alerts. In this post, we’ll guide you through troubleshooting the issue and properly setting up your push notification payloads for both iOS and Android devices.

The Problem

You might be encountering issues with your push notifications due to incorrect payload structure. For instance, here's a payload you might be sending:

While the data part is useful for Android, it's not adequate for iOS applications. You might have noticed that changing aps to notification works but affects the Android device functionality. We need a solution that caters to both platforms without causing issues.

Understanding Payload Configuration

Proper Payload Structure for iOS

When sending push notifications to iOS devices, it is crucial to use the aps dictionary to format your payload correctly. Here’s an example of the ideal payload structure for iOS (when sending via APNS directly):

Combined Payload for FCM

If your intention is to send notifications via Firebase Cloud Messaging, you'll want to configure your payload correctly for both platforms. Here’s how you can structure a combined payload:

In the above payload, the notification part is for displays to iOS while the data part can help provide additional context or arguments for your app (useful to both Android and iOS).

Note on Receiving Notifications

In your didReceiveRemoteNotification function, you should be aware that this method processes the payload in accordance with iOS conventions, so ensure your implementation reads the payload structure properly:

Conclusion

Getting the push notifications to work seamlessly across both iOS and Android can be a troublesome task, but ensuring that your payload structure is accurate and tailored to each platform is key. By adhering to the specifications laid out above, you can significantly reduce the chances of running into issues related to push notifications in your Swift 5 application.

If you incorporate these payload structures into your project, you should find that your push notifications are delivered more reliably across platforms. Have questions or ideas for further improvements? Feel free to share your thoughts in the comments below!
