UICommand is disabled on UIMenu inside NSMenuToolbarItem.itemMenu on Catalyst

Question

Before beta 4 this worked as expected. After updating to beta 4, all my UICommands inside UIMenu on NSMenuToolbarItem.itemMenu are now disabled, and I can't figure out how to enable them.

Here's my itemForItemIdentifier method:

Code Block func toolbar(_ toolbar: NSToolbar, itemForItemIdentifier itemIdentifier: NSToolbarItem.Identifier, willBeInsertedIntoToolbar flag: Bool) -> NSToolbarItem? {
		let item = NSMenuToolbarItem(itemIdentifier: itemIdentifier)
		item.itemMenu = UIMenu(title: "", options: .displayInline, children: [UICommand(title: "Test", action: #selector(onTestTap))])
		item.image = UIImage(systemName: "ellipsis.circle")
		return item
}

Am I doing something wrong or is this a bug on macOS Big Sur beta 4?

Answer 1

I submitted feedback for this. I saw the same regression between beta3 and 4. In my case I was actually assigning a UIMenu of UIActions, so there was no chance of an un-found selector causing the disabled state.

I've got this bug as well in XCode 12.4. Submenus are disabled. Any thoughts?

Edit: Using UIAction instead for UICommand fixed it!

Answer 4

When using a UICommand in a menu, the an object that responds to the selector must be somewhere in the responder chain, starting from the first responder, or if the first responder is nil, a view belonging to the frontmost UIViewController.

Which object is responding to the onTestTap selector?
