Align Edges

Attaching any UI component to its superview with NSLayoutConstraint:

NSLayoutConstraint.activate([
view.topAnchor.constraint(equalTo: superview.topAnchor, constant: 0),
view.leadingAnchor.constraint(equalTo: superview.leadingAnchor, constant: 0),
view.bottomAnchor.constraint(equalTo: superview.bottomAnchor, constant: 0),
view.trailingAnchor.constraint(equalTo: superview.trailingAnchor, constant: 0)
])

with WHCustomizeConstraint:

view.alignAllEdgesWithSuperview()

or:

view.alignEdgesWithSuperview([.left, .right, .top, .bottom], constants: [0,0,0,0])

Center in Superview

Keeping a view (UI-component) to the center of its superview with NSLayoutConstraint:

NSLayoutConstraint.activate([
view.centerXAnchor.constraint(equalTo: superview.centerXAnchor, constant: 0)
view.centerYAnchor.constraint(equalTo: superview.centerYAnchor, constant: 0)
])

with WHCustomizeConstraint:

view.centerInSuperView()

Usage

Constraints with Superview

Center Horizontally in Superview

Constraining a view Horizontally to the center of its supperview with WHCustomizeConstraint:

view.centerHorizontallyInSuperview()

Center Vertically in Superview

Constraining a view Vertically to the center of its supperview with WHCustomizeConstraint:

view.centerVerticallyInSuperview()

Edge Superview Safe Area

Attaching a view with superview SafeArea with padding using WHCustomizeConstraint:

view.alignEdgeWithSuperviewSafeArea(.top, constant: 10)

Top to Bottom & Bottom to Top

This constraints the top-anchor of secondView to the bottom-anchor of firstView:

secondView.topToBottom(firstView)
or
secondView.topToBottom(firstView, constant: 10)

This constraints the bottom-anchor of firstView to the top-anchor of secondView:

firstView.bottomToTop(secondView)
or
firstView.bottomToTop(secondView, constant: 10)
