Swift program to swap two numbers using the bitwise XOR operator

Here, we are going to learn how to swap two numbers using the bitwise XOR operator in Swift programming language?
Submitted by Nidhi, on June 04, 2021

Problem Solution:

Here, we will create two integer variables and then we will interchange the values of variables using the Bitwise XOR (^) operator.

Program/Source Code:

The source code to swap two numbers using the Bitwise XOR (^) operator is given below. The given program is compiled and executed successfully.

// Swift program to swap two numbers using
// bitwise XOR (^) operator

import Swift;

var num1 = 5;
var num2 = 8;

print("Numbers before swapping:");
print("\tNum1: ",num1);
print("\tNum2: ",num2);

num1 = num1 ^ num2;
num2 = num1 ^ num2;
num1 = num1 ^ num2;

print("Numbers after swapping:");
print("\tNum1: ",num1);
print("\tNum2: ",num2);

Output:

Numbers before swapping:
        Num1:  5
        Num2:  8
Numbers after swapping:
        Num1:  8
        Num2:  5

...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 two integer variables num1 and num2 that are initialized with 5, 8 respectively. Then we interchanged the values of variables using the bitwise XOR (^) operator and printed the result on the console screen.
