minimumItemSpacing -> Spacing between rows(vertical layout) or colums(horizontal layout)
rowHeight -> Row height of the main vertical stack view
maximumRowCount -> Maximum row count of the vertical stack view, ignores the rest of the subviews if the actual row count exceeds the limit
columnWidth -> Column width of the main horizontal stack view
maximumColumnCount -> Maximum column count of the horizontal stack view, ignores the rest of the subviews if the actual column count exceeds the limit
minimumInteritemSpacing -> Spacing between items in a row/column
insets -> Layout margins of main vertical stack view
subviews -> View array of elements to be added to the main stack view
