11.1. Understanding the Foundation Framework

You may not know it, but you have already been using frameworks in your applications if you have been following along with the example code from this book. Every example application that's been shown so far has been a Foundation application, which means that it links with the Foundation framework.

Most languages have a standard library. The C programming language for example has the C. standard library. C++ extends the standard library to also include a standard template library. Java also has a standard library, and so on. In most cases, these standard libraries are specified as providing certain functionality, but implementation is left to the platform vendors.
