Protocols have many advantages. The idea is to provide a way for classes to share the same method and property declarations without inheriting them from a common ancestor. This is especially useful in Objective-C when using the delegation pattern, on which the iOS and Mac OS SDKs rely heavily. There’s plenty of information out there on the subject, including a good overview in Apple’s developer documentation.
