Structure

objc_object

A pointer to an instance of a class.

Overview

When you create an instance of a particular class, the allocated memory contains an objc_object data structure, which is directly followed by the data for the instance variables of the class.

The alloc and allocWithZone: methods of the Foundation framework class NSObject use the function class_createInstance(_:_:) to create objc_object data structures.
