I would have assumed that this method would be called because deleting the row does in fact change the slection, or doesn't it?

OK, this is what I have in the code (XCode 7.1.1, SDK 10.11)
func tableViewSelectionDidChange(notification: NSNotification) {
print("selection did change")
}
Observing the console, I can see this is being called when I make any selection change; except when I delete the (last) selected row. Deleting the second last row does trigger a call, but only when I set the arraycontroller to 'avoid empty selection'.
