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, w

Answer 1

you need to enable the Show Assistant Editor:

Answer 2

for displaying variables only in playground, just mention the variable name without anything

let stat = 100

stat // this outputs the value of stat on playground right window

Answer 3

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.

Answer 4

As of Xcode 7.0.1 println is change to print. Look at the image. there are lot more we can print out.

Answer 5

move you mouse over the "Hello, playground" on the right side bar, you will see an eye icon and a small circle icon next it. Just click on the circle one to show the detail page and console output!

Answer 6

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.
