Focus v0.0.1 Release Notes

Release Date: 2015-07-05 // over 8 years ago
  • Focus is an Optics library for Swift that includes Lenses, Prisms, Isos, and the underlying Indexed Monads and Comonads that make it all happen.

    The Lens family is a useful way of describing first-class traversals, references, and relationships between data structures and their component parts. In Swift, this presents a fantastic opportunity to recast setters and getters of even mutable objects as immutable views.
