The Hub Framework is being phased out at Spotify, and therefore we will not be maintaining it further. Welcome to the Hub Framework - a toolkit for building native, component-driven UIs on iOS. 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.
