CocoaTouch/iOS is a verbose framework. These extensions hope to make development in rubymotion more enjoyable by tacking “UI” methods onto the base classes (String, Fixnum, Float). With sugarcube, you can create a color from an integer or symbol, or create a UIFont or UIImage from a string.
Some UI classes are opened up as well, like adding the <tt><<</tt> operator to a <tt>UIView</tt> instance, instead of <tt>view.addSubview(subview)</tt>, you can use the more idiomatic: <tt>view << subview</tt>.
