Possible to create UIAlertController using Apple's recommended UX guidelines?

Question

Apple's iOS UX guidelines show the following example:

...where:

• When the most likely button performs a nondestructive action, it should be on the right in a two-button alert. The button that cancels this action should be on the left.

• When the most likely button performs a destructive action, it should be on the left in a two-button alert. The button that cancels this
  action should be on the right.

However, it does not seem possible to implement this guidance with the current iOS APIs (testing on iOS 9 with Swift). Here's one attempt. But I've tried varying the order of adding the alert actions, and changing which action is .Default vs. .Cancel style. No combination appears to work.

@IBAction func showAlertAction(sender: AnyObject)
{
    let title = "An Alert that Offers Two Alternatives Is Easy for People to Use"

    let alertViewController = UIAlertController(title: title, message: nil, preferredStyle: UIAlertControllerStyle.Alert)

    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: { (alert :UIAlertAction!) -> Void in

        print("'Cancel' tapped")
    })

    alertViewController.addAction(cancelAction)

    let safeChoiceAction = UIAlertAction(title: "Safe Choice", style: UIAlertActionStyle.Default, handler: { (alert :UIAlertAction!) -> Void in

        print("'Safe Choice' tapped")
    })

    alertViewController.addAction(safeChoiceAction)

    self.presentViewController(alertViewController, animated: true, completion: nil)
}

Result:
