Troubleshooting

Notification with images (Rich Medias) are not working

In the project navigator, select the top-level project directory and select the Open CleverPushNotificationContentExtension & CleverPushNotificationServiceExtension target in the project and targets list.

  1. Once you start with the fresh Xcode project, it will select last OS support as a deployment target for e.g (if you have generated project via XCode 12.4 and its latest OS support is 14.4 so 14.4 will be default selection on Xcode.)

  2. Unless you have a specific reason not to, you should set the Deployment Target to be iOS 10 which is the version of iOS that Apple released Rich Media for push. iOS versions under 10 will not be able to get Rich Media.

  3. You will have to make sure all the deployment targets of the extensions must be the same.

  4. In the Extension target, set Skip Install build setting to NO to test via Xcode

  5. Make sure the build number + version for the Extension target is same like the Main target

  6. An iOS device (iPhone, iPad, iPod Touch) to test on. The Xcode simulator doesn't support push notifications so you must test on a real device.

When opening a Notification, all other Notifications get cleared

This is due to iOS automatically clearing all notifications when our SDK reset the badge count to zero. This behaviour can be changed. Please refer to the Badge Counts section on the Methods page for further instructions.

Notifications not received while developing

In some cases it is needed to mark your subscriptions as "Sandbox mode" subscriptions in the CleverPush dashboard (Channels -> App Push -> Subscriptions -> Click on your subscription -> Mark as APNS Sandbox mode).

CleverPush-CleverPushResources needs to have a Provisioning Profile selected.

This is an issue since Xcode 14 as CODE_SIGNING_ALLOWED has been changed from NO to YES in Resources (see https://github.com/CocoaPods/CocoaPods/issues/11402). Add the following to the bottom of your Podfile and run pod install to solve it:

post_install do |installer|
  assertDeploymentTarget(installer)
  installer.pods_project.targets.each do |target|
    if target.respond_to?(:product_type) and target.product_type == "com.apple.product-type.bundle"
      target.build_configurations.each do |config|
          config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
      end
    end
  end
end

Custom Delegate in UNUserNotificationCenter Breaking SDK

Adding a custom delegate to UNUserNotificationCenter may break the CleverPush SDK's functionality and prevent notifications from being handled correctly.

Avoid setting a custom delegate for UNUserNotificationCenter in your project. The CleverPush SDK internally manages notification handling, and overriding this delegate will conflict with our implementation, causing notification delivery and interaction issues.

To ensure seamless integration with CleverPush, remove any custom UNUserNotificationCenter delegate code from your app.

Silent Notification Limitations and Restrictions for iOS

  1. Silent notifications do not work on the iOS Simulator.You must test silent notifications on a physical device to ensure that background tasks and data processing are triggered properly.

  2. Silent notifications may not be delivered immediately, as the system prioritizes resources to optimize battery life and prevent unnecessary background activity.If your app uses background fetch, silent notifications can trigger it, but you must ensure that background fetch is enabled in your app settings.

  3. If your app performs too many background tasks or notifications within a short period, the system may throttle or defer the delivery of notifications.

  4. Silent notifications may also be deferred when the device is in Low Power Mode to preserve battery life.

  5. Sending too many silent notifications in a short time could lead to delivery issues or throttling by the system.

  6. If your app sends too many silent notifications within a short time, iOS may throttle or delay their delivery to optimize battery life and device performance.
