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
// Playground - noun: a place where people can play
var str = "Hello, playground"
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:
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
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.
