WWLayout

Easy to write auto layout constraints, with minimal extensions to standard namespaces.

Feature Highlights

Easy to use, readable API
Backwards-compatible (i.e. pre iOS 11) Safe Area constraints
Tag constraints to easily switch between different layouts (coming soon)
Automatic switching of size-class based constraints (coming soon)

Introduction

Constraints are added to a view using the view's layout property, like so:

    myView.layout.width(400)

Multiple constraints are easily added by chaining calls:

    myView.layout.width(400).height(200)

A more complicated example:

    let container = UIView()
    let child = UIView()

    container.layout.fill(.safeArea)

    child.layout
      .fill(container, axis: .x, inset: 20)
      .center(in: container, axis: .y, priority: .high)
      .top(.lessOrEqual, to: container, offset: 100)
      .height(toWidth: 0.5)
