* Declarative - Tell the framework what the layout of your views should be and let the framework intelligently add/modify/remove constraints and views for you.
* Expressive - Let your code visually express the hierarchy of your views.
* Fast - The example below, running on an iPhone X will update the layout in under 3 milliseconds.
* Flexible - Write the same constraints you already do, using whatever autolayout constraint DSL you prefer.
* Small - Small and readable Swift 4 codebase.
