Apple Push Notification Changes for iOS 11

Push Notification

With the advent of iOS 11, Apple has introduced changes in the way they handle certain kinds of push messages. This was done to improve battery life, but comes at a cost of user experience that is likely to affect your app.

What Apple has done is to implement a service called the “DuetActivitySchedulerDaemon” (DASD). Part of the job of this service is to measure how frequently your app is used. If your app is not used frequently, DASD may delay or discard push messages sent to your app which have the content-available flag set.

On iOS 10, Apple acknowledged a defect where push notifications containing content-available would not be delivered after an app was force-closed and rebooted. Based on what Apple has delivered in iOS 11, we assume this defect will not be fixed.

Until we have engineered solutions to work around this issue, be aware when deploying:
  • silent (data) pushes
  • in-app messages
  • pushes with dynamic categories
  • simple pushes which have more than one associated action (these are implemented with dynamic categories)
  • API pushes you send which include content-available
These messages all make use of the content-available flag and may not be delivered except to those users who use your app frequently (multiple times a day). Simple messages with only one associated action are unaffected by this issue.

We will provide a new WCA SDK for iOS that works around these Apple issues. An ETA for that SDK should be available soon.

For further technical details, see the discussion here:
https://stackoverflow.com/questions/44796613/silent-pushes-not-delivered-to-the-app-on-ios-11/

This issue won’t be seen when your app is connected to the debugger, but will appear in production apps.

Users of Xtify 2.x product who include the “Content Available” flag in their campaigns will also be affected by this Apple decision.

Master Map & Filter, Javascript’s Most Powerful Array Functions

Master Map & Filter, Javascript’s Most Powerful Array Functions Learn how Array.map and Array.filter work by writing them yourself This article is for those who have written a  for  loop before, but don’t quite understand how  Array.map  or  Array.filter  work. You should also be able to write a basic function. By the end of this, you’ll have a complete understanding of both functions, because you’ll have seen how they’re written. Array.map Array.map  is meant to transform one array into another by performing some operation on each of its values. The original array is left untouched and the function returns a new, transformed array. For example, say we have an array of numbers and we want to  multiply each number by three . We also don’t want to change the original array. To do this without  Array.map , we can use a standard for-loop. for-loop var originalArr = [1, 2, 3, 4, 5]; var newArr = []; for(var i = 0; i < originalArr.length; i+...

But before proceeding further import LocalAuthentication class in BioMetrixFile. Now, create typealias for success or failure blocks to well manage Authentication Success or Failure. public typealias AuthenticationSuccess = (() -> ()) public typealias AuthenticationFailure = ((AuthenticationError) -> ()) Now written all s...

React Native: How To Open App Settings Page

  React Native: How To Open App Settings Page React Native has a Linking module to manage the interaction with other applications in the device. In this article, I will explain how you can open “Application Setting Page” of the device using. Sample Case Before I explain how to do this, I’ll talk about an example case where we might need this: You need to get location permission within the application from a user using an iOS operating system and you asked for permission. But user did not agree to grant this permission the first time. In this case, you cannot ask your user for location permission the second time. In this case, the only thing to do is to direct the user to the settings page of our application and make it manually allow it. Now that we have explained our example situation, we can move on to how we can redirect our user to the “settings page of our application”. Open App Settings Page iOS If our user is using an iOS operating system, we can handle the whole process wit...
