Abstract
Protocols are used to define a set of methods and properties independently of a class. Any class can adopt a protocol, which means that the class implements the properties and methods defined by the protocol. In effect, protocols define a contract that classes can agree to fulfill. When a class adopts a protocol, you can be confident that the class will have implemented the properties and methods in the protocol.
