Core Data takes advantage of the Objective-C language and its runtime, and neatly integrates with the Core Foundation framework. The result is an easy to use framework for managing an object graph that is elegant to use and incredibly efficient in terms of memory usage. Every component of the Core Data framework has a specific purpose and function. If you try to use Core Data in a way it wasn't designed for, you will inevitably end up struggling with the framework. Developers new to the Core Data framework often confuse it with and expect it to work as a database. If there's one thing I hope you'll remember from this series, it is that Core Data isn't a database and you shouldn't expect it to act like one. It's the Model in the Model-View-Controller pattern that permeates the iOS SDK. Core Data isn't the database of your application nor is it an API for persisting data to a database. Core Data is a framework that manages an object graph. It&

  Foundation Framework is Foundation for making       iOS Applications  The Foundation framework defines a base layer of Objective-C classes.  The Foundation framework is designed with these goals in mind: Provide a small set of basic utility classes. Make software development easier by introducing consistent conventions for things such as deallocation. Support Unicode strings, object persistence, and object distribution. Provide a level of OS independence, to enhance portability. The Foundation framework includes the root object class, classes representing basic data types such as strings and byte arrays, collection classes for storing other objects, classes representing system information such as dates, and classes representing communication ports.  "An immutable string is a text string that is defined when it is created and subsequently cannot be changed. An immutable string is implemented as an array of Unicode characters (in other words, a t
