stackedItemSpacing
The amount of space to insert between stacked tab bar items.
Declaration
var stackedItemSpacing: CGFloat { get set }Discussion
When the stackedItemPositioning property is set to UITabBar.ItemPositioning.centered, UIKit uses this property to determine how much space to insert between the items. The default value of this property is 0, which causes UIKit to insert a system-defined default space between items. For any values above 0, UIKit inserts the specified amount of space, measured in points, between the items. If you try to assign a negative number to this property, UIKit sets the value to 0 instead.
