Swift Program to Concatenate Two Strings

1. Introduction

String concatenation is a fundamental operation in most programming languages. In Swift, concatenating strings is as simple as adding them together using the '+' operator. This tutorial will guide you through the process of concatenating two strings in Swift.

2. Program Overview

The primary steps for our program will be:

1. Declare two separate strings.

2. Concatenate the two strings.

3. Display the concatenated string.

3. Code Program

// Declare two strings
let firstString = "Hello, "
let secondString = "World!"

// Concatenate the two strings
let concatenatedString = firstString + secondString

// Display the concatenated string
print(concatenatedString)

Output:

Hello, World!

4. Step By Step Explanation

1. Initially, we declare two separate strings named firstString and secondString, initialized with "Hello, " and "World!", respectively.

2. For concatenation, we simply use the '+' operator. The result is stored in a new variable, concatenatedString.

3. Finally, we print out the concatenatedString to display the result.

Swift makes it incredibly straightforward to concatenate strings. This is just one example of how the language has been designed for clarity and ease of use, especially when it comes to common operations like string concatenation.
