 - **Powered by AutoLayout since the beginning**; it uses a combination of `UIScrollView + UIStackView` to offer an animation friendly controller ideal for fixed and dynamic row sizing.
 - **You don't need to struggle yourself with view recycling**: suppose you have a layout composed by several different screens. There is no need of view recycling but it cause a more difficult managment of the layout. With a simpler and safer APIs set `ScrollStackView` is the ideal way to implement such layouts.
