xcode6 - How to print to console using swift playground?

Question

I have been following the Apple Guide for their new language swift, but I don't understand why the bar on the right is only showing "Hello, playground" and not "Hello, world". Can someone explain why the println isn't being printed on the right?

// Playground - noun: a place where people can play

import Cocoa

var str = "Hello, playground"

println("Hello, world");

In Xcode 6.3 and later (including Xcode 7 and 8), console output appears in the Debug area at the bottom of the playground window (similar to where it appears in a project). To show it:

• Menu: View > Debug Area > Show Debug Area (??Y)

• Click the middle button of the workspace-layout widget in the toolbar

  

• Click the triangle next to the timeline at the bottom of the window

  

Anything that writes to the console, including Swift's print statement (renamed from println in Swift 2 beta) shows up there.

In earlier Xcode 6 versions (which by now you probably should be upgrading from anyway), show the Assistant editor (e.g. by clicking the little circle next to a bit in the output area). Console output appears there.
