Program/Source Code:

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

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

import Swift

func MyFun(SayHello: @autoclosure() -> ())
{
    SayHello()

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

Explanation:
