How to display an activity indicator with text on iOS 8 with Swift?

Question

I wanna show, programmatically, an activity indicator with text, like the one in the Photos app (after editing and saving a picture). How can I do this?

Heres how this code looks:

Heres my drag and drop code:

var boxView = UIView()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    view.backgroundColor = UIColor.blackColor()
    addSavingPhotoView()

    //Custom button to test this app
    var button = UIButton(frame: CGRect(x: 20, y: 20, width: 20, height: 20))
    button.backgroundColor = UIColor.redColor()
    button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)

    view.addSubview(button)
}

func addSavingPhotoView() {
    // You only need to adjust this frame to move it anywhere you want
    boxView = UIView(frame: CGRect(x: view.frame.midX - 90, y: view.frame.midY - 25, width: 180, height: 50))
    boxView.backgroundColor = UIColor.whiteColor()
    boxView.alpha = 0.8
    boxView.layer.cornerRadius = 10

    //Here the spinnier is initialized
    var activityView = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.Gray)
    activityView.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
    activityView.startAnimating()

    var textLabel = UILabel(frame: CGRect(x: 60, y: 0, width: 200, height: 50))
    textLabel.textColor = UIColor.grayColor()
    textLabel.text = "Saving Photo"

    boxView.addSubview(activityView)
    boxView.addSubview(textLabel)

    view.addSubview(boxView)
}

func buttonAction(sender:UIButton!) {
    //When button is pressed it removes the boxView from screen
    boxView.removeFromSuperview()
}
