title: How to implement support for copy keyboard shortcut in UICollectionViewCell?
body: <p>If you implement <code>override func copy(_ sender: Any?) {}</code> in a view controller, present that view controller, then hold down command the keyboard shortcuts overlay appears revealing Copy is an available action. But if you do that in a collection view cell then focus on one of those cells (highlight it via arrow keys) and hold command, copy is not listed. In iPadOS 15, the responder chain starts at the focused view, so I thought this would work.</p>
  <p>If you implement <code>override func printContent(_ sender: Any?) { }</code> in the cell (and add the key to the info.plist to indicate print is supported), then Print is listed as an available keyboard shortcut when the cell is focused. This is super similar to copy so I’m confused why works for print but not copy.</p>
  <p>Is there something more I need to do to support copy in cells?</p>
