Swift Program to Print object of a class

In this article, we will learn how to write a swift program to print object of a class.

A class object is known as an instance of a class. For example, colour is a class then obj1, obj2, obj3 and obj4 are the objects from the class. A class can have multiple objects.

Syntax

var objectname = Classname()

Here, using the above syntax we can create an object of a class.

Algorithm

Step 1 − Create a class with properties and a constructor.

Step 2 − Create a function to print the object of the given class.

Step 3 − Create an object or the class and assign value to it.

Step 4 − Call the function(created in step 2) and pass the object into it.

Step 5 − Print the output.

Example

Following Swift program to print object of a class.

import Foundation
import Glibc

// Creating a class
class Writer {
   var name: String
   var articleCount: Int
   var language: String

   // Constructor
   init(name: String, articleCount: Int, language: String) {
      self.name = name
      self.articleCount = articleCount
      self.language = language
   }
}

// Function to print object in more readable form
func printObject(objClass: Writer) {
   print("Name: \(objClass.name)")
   print("Article Count: \(objClass.articleCount)")
   print("Programming Language: \(objClass.language)")
}

// Creating object
let objClass = Writer(name: "Mohina", articleCount: 70, language: "C#")
printObject(objClass: objClass)

Output

Name: Mohina
Article Count: 70
Programming Language: C#

Here in the above code, we create an object of writer class with the name = Mohina, articleCount = 70 and language = C# and then call printObject() method to print the object’s properties.

Example

Following Swift program to print object of a class.

import Foundation
import Glibc

// Creating a class
class Food {
   var name: String
   var Count: Int
   var Sale: Int

   // Constructor
   init(name: String, Count: Int, Sale: Int) {
      self.name = name
      self.Count = Count
      self.Sale = Sale
   }

   // Property to print object in more readable form
   var printObject: String {
      return "Name: \(name), Per Day Count: \(Count), Sale: \(Sale)%"
   }
}

// Creating object
let object = Food(name: "Pizza", Count: 100, Sale: 90)
print(object.printObject)

Output

Name: Pizza, Per Day Count: 100, Sale: 90%

Here in the above code, we create an object of the Food class with the name = Pizza, Count = 100 and Sale = C#. Now we call the printObject property of the Food class to display the object.

Conclusion

So this is how we can print the object of a class either using function or property.
