Discussion
This method calls the present(_:animator:) method on self (the presenting view controller), and passes a popover animator to that method.
The presented view controller is the delegate and the content view controller of the popover. You can use NSPopoverDelegate methods to customize the popover.
To dismiss the popover, call the dismiss(_:) method on self (the presenting view controller).
