Objective-Chain is made up of Foundation and additional libraries that are built on top of it:

• Defines abstract Producer and Consumer as well as some of their basic concrete subclasses: Command, Bridge, Hub, Subscriber.
• Factories for the most essential Transformers and Predicates.
• Provides Accessor classes for accessing and modifying key-paths and structure members.
• Implementes Property Bridge, one of the main Producers / Consumers which uses KVO and KVC.
• Wrapper for GCD queues as a Queue class, which is used by Connections.
• Includes some utility categories and classes that are used in other classes.
• Provides a set of Math transformers for doing arithmetic, rounding or trigonometry.

• Provides Transformers and Predicates for working with geometric structures like Point, Size, Rectangle, Affine Transfrom and Edge Insets for iOS targets.
