Return Value

Discussion
For example, when this method is passed a layout direction of UIUserInterfaceLayoutDirection.rightToLeft and a semantic content attribute of UISemanticContentAttribute.playback, it returns UIUserInterfaceLayoutDirection.leftToRight. Although layout and drawing code can use this method to determine how to arrange elements, it might be easier to query the container view’s effectiveUserInterfaceLayoutDirection property instead.
