I have an app built with Mac Catalyst. It has a sidebar which built with UICollectionViewListCell. And I use the defaultContentConfiguration to setup my cell.
But when I try to set the selected cell's image's tintColor to white, the image become gray.
I found that set the UISplitViewController's primaryBackgroundStyle to none rather than sidebar can solve this problem, but I need the sidebar appearance.

I noticed that in wwdc-20-10056 video, when adding a new recipe, the app will show the UI in a separated window. But I can’t find any information about how to implement this. So I want to know how to implement this feature.
By the way, is there any way to use NSAlert with Mac Catalyst?
