animateRowAndSectionChanges works for particular types of nested collections only

[gerchicov-bp]

I have the following code:

class Item {
...
}
class Group {
...
var items = [Item]()
}
var groups = [Group]()

groups is a nested collection too but your code doesn't work with it.

Sorry for the delay in responding - could you share some more context here, please? I'm not clear on what's not working as expected in your example.
