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.
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
