Class And Structure in swift

Updated 31 August 2020


Class And Structure in swift are good choices for storing data and modeling behavior in your apps, but their similarities can make it difficult to choose one over the other.

Consider the following recommendations to help choose which option makes sense when adding a new data type to your app.

Class And Structure in swift are general-purpose, flexible constructs that become the building blocks of your program’s code. You define properties and methods to add functionality to your structures and classes using the same syntax you use to define constants, variables, and functions.

Comparing Structures and Classes

Structures and classes in Swift have many things in common. Both can:

Classes have additional capabilities that structures don’t have:

Since a class is a reference type and it supports inheritance, the complexity increases. In most cases, a struct should be enough to meet your needs. Use a class when they’re appropriate or necessary

Design Class

To demonstrate the difference between classes and structs, first design a class, HumanClass that has a name property.

Create Instance

Create another instance that “copies” humanClassObject

Change the name property of newHumanClassObject to “Bobby”.

The name property of newHumanClassObject has been changed to “Bobby” as well.

Struct Design

Let us find out if the same behavior occurs with an object created with structs

Create Instance

Create another instance that “copies” structObject

Change the name property of structObject to “Bobby”.

On the contrary, the change in the name property of structObject has no effect on

The graph below shows the fundamental difference between value types vs reference types.




Thanks for reading this blog, this will help you to add the class or structure in your project and You can know more from here.
