Yeah, see, that's what I _thought_ but then when I tried to override:
public NSArray<LotCode> lotCodes() ... in my Part class
with
public NSArray<ManufacturedBatch> lotCodes() in my Intermediate
class (subclass of Part)
Yes, this is because while ManufacturedBatch is a subclass of LotCode,
unlike the case of java arrays, NSArray<ManufacturedBatch> is not a
"subclass" of NSArray<LotCode>, so you don't ACTUALLY have covariant
return types here. If you were returning a to-one relationship, this
would work as expected.
