Support for cloud saving on iOS?

I can see that cloud support on Android is built into fbricker’s extension, shown here:

But are there any existing extensions for cloud save on iOS? Or any reference material on setting it up?

I’m using PlayFab as my cross-platform cloud save solution. Since they had an AS3 SDK, it wasn’t hard to translate it to Haxe.

Interesting. I was hoping to keep the amount of third party integration to a minimum, but I’ll have to give them a look. Thanks!
