Problem Solution:

Here, we will create a function and pass a closure as a function parameter.

Program/Source Code:

The source code to pass a closure as a function parameter is given below. The given program is compiled and executed successfully.

// Swift program to pass a 
// closure as a function parameter

import Swift

func MyFun(SayHello: () -> ())
    print("Hello India")

MyFun(SayHello : {
    print("Hello World")


Hello India
Hello World

...Program finished with exit code 0
Press ENTER to exit console.


In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift

Here, we created a function MyFun(). The MyFun() function used closure as a parameter. Then we called SayHello() closure from MyFun() function and printed the messages on the console screen.
