IOS Push notification

I developed my Android version, and now it is time for the IOS version ,

So is there a push notification option for IOS like the one in Android? if not , is there any recommended alternative ?

I would say there isn’t an option considering android just got push notifications recently and it is still in experimental while IOS is WAY behind android due to it being released so early. Many features are still missing in IOS so it probably won’t come for a while. I don’t know of any alternatives and I’m not sure if IOS can even support extensions yet.
