Mac Catalyst tableView.allowsMultipleSelection = true

Hello there :)

I have a UITableView where I have tableView.allowsMultipleSelection = true. This works just fine on iOS, i.e., I can select/deselect zero, one or more cells...

But on Mac Catalyst (macOS 10.15.7) I have the following problems:

1) I cannot select more than one cell. I have tried to Cmd+click and Ctrl+click but it makes no difference.

2) If I iterate over all the cells and programmatically selects them all then tableView.indexPathsForSelectedRows always returns the last selected IndexPath only.

In both cases I have checked that tableView.allowsMultipleSelection = true is still true afterwards.

This is really frustrating as I wanted to ready my app for Mac Catalyst and kinda assumed that UITableView was fully supported...

Any clues why this isn't working for me? Any workarounds?

Thanks!

Best regards,
