Submitted by Nidhi, on June 10, 2021

Problem Solution:

Here, we will create two strings and then we will concatenate them using the "+" operator. After that, we will print the concatenated string on the console screen.

Program/Source Code:

The source code to concatenate two strings is given below. The given program is compiled and executed successfully.

// Swift program to concatenate two strings

var str1 = "Hello "
var str2 = "World"
var str3 = ""

str3 = str1 + str2

print(str3)

Output:

Hello World

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

Here we created three string variables str1, str2, str3. Then we concatenated str1 and str2 using the "+" operator and assigned the result into the str3 variable. After that, we printed the str3 variable on the console screen.
