Please describe the issue:
Couple of issues when using split-screen in the sample "Adding Menus and Shortcuts to the Menu Bar and User Interface" downloadable at:
https://developer.apple.com/documentation/uikit/uicommand/adding_menus_and_shortcuts_to_the_menu_bar_and_user_interface
Date of files inside zip: 12 Feb 2020

I've also attached the zip containing the sample.

Can the sample be improved to use proper practices so it works with split-screen?
Please list the steps you took to reproduce the issue:
Issue 1 - A crash when adding a row:
Open project
Select simulator iPad Pro (11inch) (2nd gen)
Launch app
Drag up from bottom of screen to show dock
Drag messages on to right side of screen so you have split view with this sample app on the left and Messages on the right (not floating).
Tap plus button

Issue 2 - Selection not working
Drag the split divider to the right so Messages dissapears and the sample app is now fullscreen.
Add some rows.
Drag up from bottom and drag messages into right side split screen.
Select a row.
What did you expect to happen?
Issue 1
New row should appear in table.

Issue2
Detail view should be pushed on navigation controller.
