Here, we will demonstrate the logical NOT (!) operator and print the appropriate message on the console screen.

The logical NOT operation reverse the condition result. If the result of the condition is true then it becomes false or vice versa.

var num1=10;
var num2=10;

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 variables num1, num2 that are initialized with 10, 10 respectively. Then we compared variables and performed a logical NOT (!) operation and printed the appropriate message on the console screen.
