Ios device token is not generating

i’m using ionic 1 and ionic cloud messaging for push notification it works in android but its not generating device token for ios

That is unfortunate. This happens if you made an error during implementation.

did you mean any error in generating the APN and p12 certificates ?

I have no idea as you didn’t say a word what you did, what instructions you followed, if there was anything else going wrong etc.

i followed these and it worked for android not for ios
