I tried making a data class backed by an iOS foundation object, and kotlin didn't complain. Is this because K/N has built in facilities for generating equals and hashCode that call the NSObject equivalents?

even passes equality tests

What do you mean?

data class Date(val date: NSDate) works, even though NSDate comes from iOS. Is this support documented somewhere, by chance?

I find this behaviour natural enough, so it is not documented explicitly.

Makes sense! Thanks!
