ARCore Recording for iOS mentioned in Documentation, Not actually supported

[yosun]

We have a client who based a Unity iOS project spec on your documentation indicating ARCore Recording support on iOS.

If iOS support is indeed not implemented, please update your docs accordingly. Specifically, please indicate explicitly that this is an Android only feature.

#234 (comment)

The official Google ARCore documentation for recording mentions iOS and non-Android platform support nonetheless - is the documentation incorrect then?
