dividerColor
The color of the dividers that the split view draws between subviews.
Declaration
@NSCopying var dividerColor: NSColor { get }Discussion
The default implementation of this method returns clear when the split view’s dividerStyle is NSSplitView.DividerStyle.thick, or when dividerStyle is NSSplitView.DividerStyle.paneSplitter and the split view is in a textured window. The system draws all other thin dividers with a color that provides appropriate contrast between two white panes.
You can subclass NSSplitView and override this method to change the color of dividers.
