How can vCenter the relative view offset?

[Paris Meta]

How can I cover the AutoLayout like below to PinLayout.

let view1 = UIView()
let view2 = UIView()
addSubview(view1)
addSubview(view2)
        
view1.centerXAnchor.constraint(equalTo: view2.centerYAnchor, constant: -20)
view1.widthAnchor.constraint(equalTo: view2.widthAnchor, constant: -20)

The width of viewA is 80% relate the superview.

And how can I set the width of viewB is less than the width of viewA, like 20px?

import PinLayout

// ...

view1.pin.width(80%)
view2.pin.width(view1.frame.width - 20).center(to: view1.anchor.center)
