Submitted by Nidhi, on July 12, 2021

Problem Solution:

Here, we will create a closure function with two parameters to add numbers. Closures are special functions. We can define a closure function without using the "func" keyword and function name.

Program/Source Code:

The source code to create a closure function with parameters is given below. The given program is compiled and executed successfully.

// Swift program to create a 
// closure function with parameters

import Swift

// Define a closure
let AddNum = {
    (num1:Int, num2:Int) in
    print("Sum is: ",num1 + num2)
}

// call the created closure
AddNum(10,20)

Output:

Sum is:  30

...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 a closure function AddNum() to with two integer parameters num1, num2 and add both numbers and printed the result on the console screen.
