...It is designed to enable teams of any size to quickly build, tweak and ship new UI features, in either new or existing apps. It also makes it easy to build backend-driven UIs. Instead of building UIViewControllers that each has hard-wired behaviors for UI in terms of controls, data binding & selection handling - a Hub Framework-powered UI is all about components. Components can be reused and rearranged in any way, and render any model. They each define a rectangle on the screen in which anything can be rendered, making it easy to quickly iterate on UI and create modular building blocks that reduce the need for code duplication.
