This is a full rewrite of SwiftAutoLayout with the following major changes/additions:
- Setting layout priorities is supported using the ~ operator
- Support for
UILayoutGuideandNSLayoutGuide - Support for constraining using
UIViewControllerlayout guides - Layout item types are now parametrized using a shadow type that determines whether the constraint is an X axis, Y axis, or dimension constraint for additional type safety
- The
al_prefixes have been dropped from the layout item accessors (e.g.view.al_leftis nowview.left) - The method equivalents (e.g.
greaterThanOrEqualTo()instead of>=) to the operator overloads have been removed since these are needlessly verbose and do not add much value over using the(NS|UI)LayoutAnchorAPI
