Pushkit toxicity does not hit some iOS devices

It should work on all devices with proper integration. nothing changes for any particular device.

You can cross check your steps.

Swift

import PushKit

class AppDelegate: UIResponder, UIApplicationDelegate,PKPushRegistryDelegate {

    var window: UIWindow?

    var isUserHasLoggedInWithApp: Bool = true

            viewAccept.identifier = "VIEW_ACCEPT"
            viewAccept.title = "Accept"
            viewAccept.activationMode = .Foreground
            viewAccept.destructive = false
            viewAccept.authenticationRequired =  false

Updated answer

Below are some troubleshooting options.

(1) Change the com id and try again

(2) Save puhkit code in delegeate app

I think you can change your bundle id and try again, it should work with all devices.
