Auto Layout convenience with minimal API surface area, but high expressive power
- Minimal API accessible through
constraintproxy - Direct access to created
NSLayoutConstraint -
UILayoutGuidesupport - New
UILayoutPriorityconstants including.maxNonRequired(999) for resolving layout ambiguities -
translatesAutoresizingMaskIntoConstraintsis automatically set tofalseon a target

subview.constraint.edges(to: view.layoutMarginsGuide)subview.constraint.lastBaseline(to: view.safeAreaLayoutGuide, .bottom)subview.constraint.width(to: view.readableContentGuide)Allmost all constraint methods have relation parameter.
subview.constraint.leading(to: view, relation: .greaterThanOrEqual)All constraint methods have priority parameter.
subview.constraint.leading(to: view, priority: .defaultLow)Constraints are created active by default. All constraint methods have active parameter to opt out of this.
