In this Swift tutorial, I’ll show you how to add new functionality to existing Swift classes using class extensions. It’s a powerful feature in Swift that lets you add your own methods or computed properties to already-defined classes, making them more versatile. Let’s start with a very simple example. Creating a Simple Extension In Swift,…

In this tutorial, we will explore how to use the Comparable protocol to compare custom objects based on their properties, and the Equatable protocol to determine whether two objects are equal. By the end of this tutorial, you will…

Introduction to Singleton Design Pattern The Singleton design pattern guarantees that only one object of a class will exist in a system. This is done in Swift by creating a class with a private initializer. The private initializer ensures that…

After learning the basics of creating classes in Swift, you can dive deeper and learn how to implement a Singleton pattern in Swift, and create a class that has only one instance throughout your project. Alright, so let’s begin by declaring…

Read More Singleton Class in Swift. Code Example.In Swift, a class or a struct can have multiple initializers which are used to create an instance of that particular type and set up its initial state. The code examples below show how to define a class with single or multiple initializers and how to create an instance of that class. Single Initializer class…
