Xcode playground not executing functions

Question

I created a new playground and I add simple function but the function is never been call:

var str = "New playground"

func hello()
{
    print("Hello, World")
}

Any of you knows why the function is not been call ?

I'll really appreciate your help

Answer 1

Because you didn't call the function. Just call it:

func hello()
{
    print("Hello, World")
}

hello()
