Can someone please help, here?

Care to elaborate why it doesn't work for .menu and works for .window? For my use case, I need the .menu.

I need a menu and not a window. Anyways, the change works! Care to explain why .menu doesn't work and .window does?

I can't imagine why Xcode can't support this simple use case (importing project from existing sources) which many other IDEs support out of the box. Switching to another IDE. VS code was able to import it instantly.

Thanks Claude31. Can you please suggest some good examples to study?

Still not completely clear to me. Lets say I click on "Family name" column, what happens next? Does the value of sortOrder variable change if I click on "Family name" column? If yes, what will be the new value? Also, how can I use custom Comparator for different columns?
