Making Image Slider with UIScrollView in Swift
<p>I am making an app that the user can upload 1 to 3 photos.
I want the user to be able to see them it as a slider in with Page Control,
I started to code it but for some reason the images do not added to the scrollView (I see nothing when running the app).</p>

<p>This is my code so far:</p>

<pre><code>    class dogProfileViewController: UIViewController {
    var imagesArray = [UIImageView()]
    @IBOutlet var scrollView: UIScrollView!
    override func viewDidLoad() {
        super.viewDidLoad()

        let image1: UIImageView = UIImageView(image: UIImage(named: "image1.png"))
        let image2: UIImageView = UIImageView(image: UIImage(named: "image2.png"))
        imagesArray.append(image1)
        imagesArray.append(image2)
        var countIndex = CGFloat(0)
        for image in imagesArray {
            image.frame = CGRectMake(countIndex*view.frame.width, 0, view.frame.width, 100)
            scrollView.addSubview(image)
            countIndex = countIndex + 1
        }

        // Do any additional setup after loading the view.
    }
}
</code></pre>
