I am trying to implement some of the methods and properties in NSOrderedSet.
The read-only property "reversedOrderedSet" has the @NSCopying attribute according to the NSOrderedSet class reference.
So, I tried to do this:
@NSCopying public var reversedOrderedSet: NSOrderedSet {
return NSOrderedSet.init(array: _orderedStorage.reverse())
}
The compiler says "@NSCopying requires the property to be mutable". When inherited by NSMutableOrderedSet, doesn't this property qualify to be mutable?
Does @NSCopying not apply here? Is my understanding of "mutable (stored) property" flawed? Or is there a problem with the implementation?
Nowhere in Foundation is @NSCopying being used currently. So don't have a "reference implementation" :)

swift-corelibs-foundation can’t really implement that in terms of adopting the decorator of @NSCopying because it does not have objc backing.

The mutable state here is a setter not a NSMutableOrderedSet

just comment it out and you will be good to go likely.
