In this tutorial, you are about to learn how you can use generics to make your code reusable and flexible in an application. You will see how to create functions and properties that can work with any type with an example. What is generics? Swift allows you to write flexible, reusable code using generics. Generic code can work with any type. You can write code that avoids duplication and expresses its intent in a clear, abstract manner. Generics are one of the most powerful features of Swift, and much of the Swift standard library is built with generic code. You’ve ... Read More
In this tutorial, you will learn the use of double question marks (?) in the Swift language. In Swift, a double question mark (??) is called the "nil−coalescing operator". This operator is basically used to provide a default value in the case of nil. In other words, when a variable is nil and you want to provide a default value in the absence of a value, use this operator. According to Apple documentation The nil-coalescing operator (a ?? b) unwraps an optional a if it contains a value, or returns a default value b if a is nil. The expression ... Read More
This guide will cover what classes and functions there are in the Swift programming language. Also, what are the differences between them? Most of the time, when we write code in a project, we have to deal with classes and structures. It is true that these two features are the most significant in Swift. In a real−time application, whatever you want to write, you need to create a class to assign responsibility. If we already have a class option, we need to understand why and when we should use the structure. Structures are one of the fundamental concepts in the ... Read More
You'll learn how to use javascript to detect the keystrokes ctrl+v in this article.

To identify whether "ctrl" is pushed or not during the key event is triggered, it produces a "boolean" value. Syntax event.ctrlKey Return Value true − After pressing ... Read More
In this tutorial, we are going to study about different types of tools required to develop iOS applications. As we already know, there are approximately 1 billion iPhone users. Thus, Apple always provides a hassle−free environment for developers who want to build applications for iPhone, iPad, MacBook, and Apple Watch. Apple has built a strong ecosystem for developers so they can focus on writing code and building apps. Today, we will see what tools we need to develop applications on the Apple platform. Xcode This is an editor or IDE to write code for building apps. Apple released the ... Read More
Computer systems have penetrated every industry, including education and working life, amusement, and social media. The result is that a great majority of people globally remain hooked up to the internet. That is where the risks begin! Being interconnected has excellent benefits, like close communication and spreading information, but crime has taken root too.
