In addition to the core Web Service-related functionality, Perfect provides a range of fundamental building blocks with which to build server side and desktop applications.

Like the JSON library discussed in previous chapters, many of these functions can be achieved by Swift's provided functions; however, Perfect's APIs aim to increase the efficiency, readability and simplicity of the end user's code.

Consult the followings sections for detailed information on the utilities available in Perfect's libraries:
