Just Press Alt   Command   Enter to open the Assistant editor  Assistant Editor will open up the Timeline view  Timeline by default shows your console output    Additionally You can add any line to Timeline view by pressing the small circle next to the eye icon in the results area  This will enable history for this expression  So you can see the output of the variable over last 30 secs  you can change this as well  of execution

You may still have trouble displaying the output in the Assistant Editor  Rather than wrapping the string in println    simply output the string  For example   for index in 1   5        The number is   index       Will write  5 times  in the playground area  This will allow you to display it in the Assistant Editor  via the little circle on the far right edge    However  if you were to println  The number is   index    you wouldn t be able to visualize it in the Assistant Editor

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  gt  Debug Area  gt  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
