Perhaps I should go through the document oriented Core Data

The "creating the user interface" part is the same whether or not
it's a document-based application.
Good to know, thanks.
Window displays a black square.
The Window hierarchy is NSWindow -> NSView -> NSScrollView ->
NSCollectionView
[...]
I end up with a black square, both in IB and when I compile and run
my application. I think the black square is the NSCollectionView.
What does this mean?
It means the primary colour of the collection view (as shown in the
IB inspector for the view) is black.
Why is this a "problem"?
Do you want to use a collection view? What are you trying to achieve?
I was expecting to get a CRUD UI like that in "NSPersistentDocument
Core Data Tutorial" Figure 2-4.
I've subsequently gone through the tutorial with a Core Data Document
based project, and I get the same (to me) unexpected result (the only
modification I made to the tutorial was to create only one entity with
only two attributes)
I will learn to do this from first principles, but I thought the
automatically created UI would be a useful starting point.
Thanks,
Tom
