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.
