The source code to demonstrate the unary minus '-' and unary plus '+' operators is given below. The given program is compiled and executed successfully.

// Swift program to demonstrate the
// unary minus '-' and unary plus '+' operators

import Swift;

var num1=0;
var num2=0;

// Unary '-' operator
num1 = -10;

// Unary '+' operator
num2 = +20;

print("Num1: ",num1);
print("Num2: ",num2);

Num1:  -10
Num2:  20

...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 variables num1, num2 that are initialized with 0. Then we assigned the values to the variables with unary minus '-' and unary plus '+' operators. We printed the result on the console screen.
