Swift - Hello World Program

The classic "Hello, World!" program is a beginner's introduction to a new programming language. It demonstrates the basic syntax to output or display a string.

In Swift, you can write the "Hello, World!" program in a simple way:

print("Hello, World!")

If you're using an environment like Xcode's playground or the Swift REPL, simply typing the above line will display "Hello, World!" as the output.

If you're creating a full Swift program using a text editor, you might structure it with a main function like this:

import Swift

func main() {
    print("Hello, World!")
}

main()

However, the simplest and most common approach, especially in playgrounds and tutorials, is the single line print("Hello, World!").
