An iOS framework from the developers at Facebook that aims to keep complex user interfaces smooth and responsive. It's built to go hand-in-hand with Pop's physics-based animations, but also works with conventional app designs and UIKit Dynamics. The framework centres around AsyncDisplayKit Nodes that provide a thread-safe abstraction layer over UIViews and CALayers. You can construct entire node hierarchies in parallel, or instantiate and size a single node on a background thread. Comes with drop-in replacements for UIImageView, UITextView and UITableView.
