iOS - Scrolling collectionview to top issue

Try adding this method:

override func viewDidLayoutSubviews() {
        self.collectionView?.setContentOffset(CGPoint.zero, animated: false)
    }

Getting NSArrayController item for right click in NSCollectionView

You might try setting the menu of each collection view item's view. Most likely, you'll do this by overriding +defaultMenu in your item view class. Once you do that, comment out the popUpContextMenu:withEvent:forView: message and see whether you can get away without it.

Furthermore, it would then not be too hard to serve up different menus for different kinds of items (e.g., folders vs. packages vs. files, and different types of files at that). You'd probably have to override -menuForEvent: instead of +defaultMenu.

Find two consecutive rows

Assuming the rows have sequential IDs, something like this may be what you're looking for:

select top 1 * 
from 
Bills b1
inner join Bills b2 on b1.id = b2.id - 1
where
b1.IsEstimate = 1 and b2.IsEstimate = 1
order by
b1.BillDate desc
