Xcode Playground Does Not Perform Functions

Question

I created a new playground and I add a simple function, but the function was never called:

var str = "New playground" func hello() { print("Hello, World") } 

Do any of you know why the function was not called?

I will be very grateful for your help.

Answer 1

Because you did not call the function. Just call it:

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