Xcode changes?

For most of the course, I've been using the Treehouse iPad app, and have had no problems. Today, I fired up Xcode on my Mac to do this lesson, and I ran into a couple of discrepancies:

1. Xcode told me to change println() to print() — no big deal, except, is it still possible to use the original functionality of print(), without a line break, if desired?

2. Show Assistant Editor doesn't show the console output. Instead, it's a mostly-empty pane. There is, however, an upward-facing arrow in the lower left-hand corner of the window with the tooltip "Show the Debug area"; this is the best I could come up with. Is this what I should be doing?

Note: I'm using the beta version, if that matters. I figure I might as well get used to the way things might be in the next version.

I didn't realize this, at first, but there's a third issue (being that do-while loops are now called repeat-while loops). All told, my code had to be changed to this, in order to be parsed correctly:

import UIKit


var todo: [String] = ["Return calls","Write blog","Cook dinner","Pickup Laundry","Buy bulbs"]

var index = 0

while index < todo.count {
    print(todo[index])
    index++
}

index = 0

repeat {
    print(todo[index])
    index++
} while index < todo.count
