Why is Xcode only printing out last item of array?

I am working on this in Swift 2. I'm trying to print out all the elements in this array, and when I display it, it only prints out Pickup laundry.

var todo = ["Return Calls", "Write blog", "Cook Dinner", "Pickup laundry"]

for element in todo { print(element) }

I'm not sure what I'm doing wrong. Also I cannot see the console in assistant editor, it does not show up.

Those print calls are console calls. Open up the debugger panel at the bottom by clicking the down arrow there and pressing the run button. You will see all the lines, not just the last line like you do on the right. The right side only shows the last result as it is designed to be interactive while you code, the right panel isn't intended to be a printout. For that you need to open the debugger panel at the bottom that is normally closed on startup.

If you click the "Show Result" button on the right side of your playground then right click the box inside the playground and hit "Value History", you will see that the For loop did complete correctly.

I actually just figured out how to do open the console, and it works properly. Thank you both!
