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.
