Ios 13 push notification changes

We discovered several technical changes to notifications in iOS 13 and Xcode 11, which have not been well-publicized by Apple. We also notified customers to make sure they're using the latest OneSignal SDK when they update their apps. But what about developers who aren't using OneSignal to send push notifications?

Maybe it's time to switch to OneSignal, where you can send push notifications to an unlimited number of mobile subscribers. Below, is everything you need to know about Xcode 11 and iOS The goal of this article is to help developers who don't yet use OneSignal.

Starting in Xcode 11, the description attribute of the deviceToken data sent to the push token delegate in iOS changed to a different format. Many existing applications and software libraries use this attribute to fetch the push token by accessing the description variable on the deviceToken NSData instance, and then trimming certain characters from it to get the device push token, like so:. If you're not a OneSignal customer, and you're not sure if you're affected — you probably are!

Thousands of books, online tutorials, popular open source libraries, and StackOverflow answers have this, now incorrect, implementation. The newly correct implementation is slightly more complicated but required to ensure that a consistently correct value is returned for iOS 13 as well as older iOS versions. Fortunately, we became aware of this change early in our testing of Xcode 11 Beta and after receiving customer feedback about this issue.

This gave us time to update all of our SDKs and notify affected customers. According to Applethis header is:.

Our findings have been that many vendors and many open-source libraries have not yet made this change. Without this, apps may find some of their notifications being unexpectedly ignored by devices. OneSignal automatically sets the new apns-push-type header to the right value for our customers. Many notification delivery systems set the apns-priority header value to 10 immediate delivery.

Or, if this kimcartoon r is omitted, a value of 10 is the default assumed by Apple. The other possible value of the apns-priority header is 5. This lower value reduces battery usage, but may result in the notification being delayed. These are notifications that may not contain user-visible data, but are used to invoke the app in the background to download updated content, such as recently received messages.

Omitting this may cause the app to not launch. Apple's documentation has some ambiguity on this field. Some Apple documentation pages indicate that apns-priority must be set to 5 for all push payloads that have content-available set to 1 true.

Other documentation pages indicate that content-available can be set to 1 and apns-priority can still be set to 10as long as the push message has content to be shown to the user via the alert field of the APNS payload.Learn how to update.

Push notifications are used by many apps to remarket and engage their users. Users that have push notifications enabled also open apps 3 times more often than those without; so you can see how powerful they can be.

However many apps are being caught out with a subtle change in iOS 13 regarding push notifications. Unless your developers have been keeping a close eye on push notification policies the chances are that your push notifications have stopped working as they did.

I deleted the app and reinstalled it, after that I can receive push notifications. Is there any changes on iOS, that affected the push notifications token or anything else? Shouldn't be, we handled the iOS 13 updates on the payload so technically you shouldn't have to change anything. Not sure why reinstall the app matters for this case.

Hi, I had same issue. I tried to solve using apns-push-typebut I couldn't. Is there any other good way?

I found patterns of iOS 13 bug or changed? Maybe you have set empty string to aps properties? I'm not able to reproduce for the case when notification field is empty second scenariowhat response do you get when it failed? I got no fail response. I'm able to reproduce the case tomokitakahashi listed, chong-shao I wonder if we silent the message when notification body is empty?

I'm not sure how Apple handle such payload especially you set content-available to true, meaning it's a hidden message, but then it has a body field. We think maybe the iOS 13 apple re-enforce on apns-push-type that such payload might not be supported. Hey pajtimid.

Since the public release of iOS 13 push notifications appear to no longer work for my Xamarin. Forms iOS project. I currently use Azure Notification Hub to send test notifications and previously, my iPhones would get notifications with no problem.

Since iOS13 this is no longer happening. Is this problem still present? Or has anyone got any sources to confirm this issue other than SignalOne? The code above worked all the time but during debugging I have noticed it no longer steps into Hub. UnregisterAllAsync and I believe it is causing some error?

Sign up or log in Sign up using Google.Apple recently made some changes to their public push service; the changes mostly aligned with the releases of iOS 13 and Xcode. This article describes the impact of these changes on Azure Notification Hubs. Apple now requires that developers identify notifications as an alert or background notifications through the new apns-push-type header in the APNS API.

According to Apple's documentation : "The value of this header must accurately reflect the contents of your notification's payload. If there is a mismatch, or if the header is missing on required systems, APNs may return an error, delay the delivery of the notification, or drop it altogether. Developers must now set this header in applications that send notifications through Azure Notification Hubs.

Due to a technical limitation, customers must use token-based authentication for APNS credentials with requests that include this attribute. If you are using certificate-based authentication for your APNS credentials, you must switch to using token-based authentication. The following code samples show how to set this header attribute in notification requests sent through Azure Notification Hubs. To help you during this transition, when Azure Notification Hubs detects a notification that doesn't have the apns-push-type set, the service infers the push type from the notification request and sets the value automatically.

Another minor change, but one that requires a change to the backend application that sends notifications, is the requirement that for background notifications the apns-priority header must now be set to 5. Many applications set the apns-priority header to 10 indicating immediate deliveryor don't set it and get the default value which is also Setting this value to 10 is no longer allowed for background notifications, and you must set the value for each request.

Apple will not deliver background notifications if this value is missing. For example:. For years, iOS developers used the description attribute of the deviceToken data sent to the push token delegate to extract the push token that a backend application uses to send notifications to the device. With Xcode 11, that description attribute changed to a different format.

Existing code that developers used for this attribute is now broken. You may also leave feedback directly on GitHub. Skip to main content. Exit focus mode. Learn at your own pace.

Doc :. It's an error to specify this priority 10 for a notification whose payload contains the content-available key.

Change 2: a new key, apns-push-type, is required when delivering notifications to devices running iOS 13 with the value background or alert. After complying with the above, I'm still seeing random behavior regarding silent remote notifications.

I can see that the notification arrives to the device and in some cases even when the device is connected to a power source the notification is dropped by the OS. Use this priority for notifications whose payload includes the content-available key. They may also be throttled, and in some cases not delivered. From what I'm seeing, silent notifications are throttled and not delivered randomly even if the battery is full and the device is connected to a power source.
