How to position one image in front of another?
<p>I'm new in Swift development, so I hope you guys can help.</p>

<p>I have a game map, it contains 50 different ImageView (position) from 1 to 50, 4 characters, and a dice roll(button).
When I press i dice roll button it returns a random number between 1 to 6.</p>

<p>For example: I pressed dice roll button and it returned 4, so now i want to move my character to new position(to ImageView place4).</p>

<p>Here is my code:</p>

<pre><code>var girl: UIImageView!
var place4 = UIImageView(image: UIImage(named: "4.png"))

girl.frame = CGRect(x: 200, y: 200, width: 45, height: 100) 
scrollView.addSubview(girl)

place4.frame = CGRect(x: 210, y: 145, width: 60, height: 30)
scrollView.addSubview(place4)

func moveCharacter(sender:UIButton!) {
let duration = 1.0
    let delay = 0.0 // delay will be 0.0 seconds (e.g. nothing)
    let options = UIViewAnimationOptions.CurveEaseInOut // change the timing curve to `ease-in ease-out`

    UIView.animateWithDuration(duration, delay: delay, options: options, animations: {
        // any changes entered in this block will be animated
        self.girl.center = CGPointMake(self.place4.center.x, self.place4.center.y - 30)

        }, completion: { finished in
            // any code entered here will be applied
            // once the animation has completed

            //self.place4.hidden = true

    })
}
</code></pre>

<p>When I press button, UIImageView "girl" should move to X and Y coordinate of UIImageView "place4". To move character to new position I use following code:</p>

<pre><code>self.girl.center = CGPointMake(self.place4.center.x, self.place4.center.y - 30)
</code></pre>

<p>and girl image should appear over place4 image, but actually girl image appear behind place4 image, pls look at the screenshot:</p>

<p>I tried to use UiView methods bringSubviewToFront and sendSubviewToBack, but it did'n help.</p>

<p>How can I fix this issue? Or maybe you guys can advise me better solution?</p>

<p>Thanks to all in advance.</p>
