NSSplitView
A view that arranges two or more views in a linear stack running horizontally or vertically.
Declaration
class NSSplitViewOverview
A split view manages the dividers and orientation for a split view controller (NSSplitViewController). By default, dividers have a horizontal orientation so that the split view arranges its panes vertically from top to bottom.
Divider indices are zero-based. If the isVertical property is false, which is the default value, the top divider has an index of 0. If isVertical is true, the leading divider has an index of 0.
