In using the engine, designers specify an object’s bounciness, its density, the level of gravity, and how things are attached to each other. In iOS 7, Apple made that technology available to UIKit-based apps as well.

The proliferation of mobile devices, increased user expectations, and the very real risks of losing customers and dropping in search result rankings have laid a heavy burden on developers to optimize loading time at all costs.
