Pushkit token not getting in some devices iOS - ios

Question

I have implemented PushKit. I've followed these steps:
1.) https://stackoverflow.com/a/38184769/4970453
2.) https://stackoverflow.com/a/28562124
I am able to get didUpdatePushCredentials device token.
working in --> iPhone 5s , iPhone6 Plus
didUpdatePushCredentials Not working in --> iPhone6 and iPhone7
I am using same cerificates and Build for all devices. Don't know the exact issue.
If anyone have faced this kind of problem, please share work-arounds.
My code and Certificate Link
code -> https://www.dropbox.com/sh/x2615t7xn8mavs3/AADbX5nBuF5_08YNPX8wI59ga?dl=0
cer -> https://www.dropbox.com/sh/70l4htj1c46emog/AABxBalaoN1JP22dQp8-mNXGa?dl=0
Solution -----> I have changed Bundle identifier And create New certificate with New BundleId.

Answer 1

Make sure that in the certificates page you have the push notifications enabled in the App ID.
Also try using a 3G/4G connection. Network configuration may be not letting the device to obtain the token.

Answer 2

It should work in all devices when integrated properly. there is nothing changed for any device specific.
You can cross verify your steps.

Updated answer
Below are some trouble shooting option.
(1) Change com identifier and try again
(2) Keep puhkit code in app delegeate
I guess, you can change your bundle identifier and try again, it has to be work with all devices.

Answer 3

For PushKit to work properly, here are steps we need to follow:
Enable Push Notifications in project Capabilities
Enable Remote Notifications in Background Modes
Connect device to internet
Allow app to receive push notifications
Please refer to this step-by-step tutorial.
As it is happening for some devices only, may 3rd and 4th steps are responsible.

Answer 4

In my case I wasn't receiving the VoIP token in some of my devices. A HARD RESET of those devices fixed my issue.
