Structures

Structure & Classes are general-purpose, flexible constructs that become the building blocks of our program's code.

Syntax:

Are you confused about Structures & Classes ?

Classes use reference counting. It means more than one variable can reference a class instance whereas Structures are values which are always copied when they are passed around.

Structures 

In this tutorial we are going to do some basic operations on a very simple struct.

What all we can do with the structure ?

• Defining properties to store values 
• Defining methods to provide functionality
• Defining subscripts to provide access to their values using subscript syntax
• Defining initialisers to set up their initial state
• Be extended to expand their functionality beyond a default implementation 
• Conform to protocols to provide standard functionality of a certain kind
