iOS 8.x app is crashing in background launch - ios

I am developing an VoIP iOS app using PushKit. After getting PushKit payload message, app supposed to be launched in background state. After receiving payload, I am initiating a socket and connecting it with the server. Everything works fine on iOS 9+ devices. But I have iPhone 5c (iOS 8.1)device on which the app crashes. I am not able to figure out the cause of crash.

IOS 12 didn't receiving app push notification only if Iphone has been reset as new

We are facing some problem about our hibryd app, in Android it works fine, in ios 11 and below our app is working. If user has an Iphone with IOS 11 and update to IOS 12 app still works, but if user reset his/her Iphone and then install the app it just doesn't send push notifications, all the notification settings are ok, this just don't have any behaviour when receiving a new message.

iOS 11 CloudKit Record changes notifications not received in Single App or Guided Access Mode

In iOS 11, no CloudKit record change notifications are received when the app is in Single App Mode (SAM) or Guided Access Mode (GAM).
The foreground app would be receiving silent notifications just fine and updating the UI, but once I put it in GAM or SAM, didReceiveRemoteNotification is not called (neither the background method nor the older foreground-only method).
I have an iOS 9 iPad in Single App Mode (SAM) that receives all the CloudKit notifications, and I remember my iOS 10 iPad also worked, so this is an iOS 11 issue.
I wonder if Apple is disabling push notifications in general if a device is in SAM or GAM?
This appears to be fixed in the newest iOS 11.2.5 beta 4. Will wait for the GM release of 11.2.5. Thanks!

iOS 8.1.2 Remote Notification Issue When App Is In The Background

I am having issues with processing push notifications in the background on iOS 8.1.2, specifically on the iPhone.
So basically, when I send a push notification to my iPad (running iOS 8.1.2), the method application:didReceiveRemoteNotification:fetchCompletionHandler: always gets called whether my app is running in the foreground or suspended in the background. However on my iPhone (also running iOS 8.1.2) the method only gets called when my app is in the foreground.
Has anyone experienced this problem before, or maybe know the solution?
FYI, my app already has the remote-notifications background mode enabled and I have added content-available = 1 to the notification payload. I am also sending the push notifications on a production environment.
