Libraries import in Objective-C

To import a library in Objective-C, you use the #import directive. You can import both Apple frameworks and third-party libraries. Here are some examples:

#import  // Importing the Foundation framework

#import "MyCustomLib.h" // Importing a custom library called MyCustomLib

#import  // Importing a third-party library called AFNetworking

When you import a library, you can then make use of its classes, functions, and other components within your Objective-C code.
