Is there any way to capture a mouse's scroll wheel movement?

The usual ways to capture a mouse's scroll wheel activity for Mac such as with


- (void)scrollWheel:(NSEvent *)event;


does not work as NSEvent apparently is not supported when building a Catalyst converted app.


The object I need to control is in a regular image container and not in a scroll view container. I am simply trying to use the scroll wheel to change the loaded image. Trackpad activity works fine but capturing the scroll wheel so far has been elusive.


Thanks!
