CALayer contents not being displayed in Swift2

import UIKit

class ViewController: UIViewController {


    @IBOutlet weak var myView: UIView!



    override func viewDidLoad() {
        super.viewDidLoad()
        let url = NSURL(string: "http://blogs.independent.co.uk/wp-content/uploads/2012/12/some-girls.jpg")
        var image : UIImage? = nil
        if let data = NSData(contentsOfURL: url!) {
         image = UIImage(data: data)
        }

        let myLayer = CALayer()
        myLayer.anchorPoint = CGPoint(x: 0, y: 0)
        myLayer.bounds = CGRectMake(0, 0, self.view.bounds.width, self.view.bounds.height)
        myLayer.position = CGPoint(x: 0,y: 0)
        myLayer.borderColor = UIColor.redColor().CGColor
        myLayer.borderWidth = 2.0
      // the image is not displayed 
        myLayer.contents = image
        print(myLayer.contents)

        myView.layer.addSublayer(myLayer)
        myView.layer.opacity = 0.3
    }


}

The UIImage is not being displayed why is that? whats wrong with the code? Please Help anyone who is well versed in Core Animation and Swift

In CALayer CGImage is used and not UIImage Hence Convert the UIImage into CGImage like this :

myLayer.contents = image?.CGImage

This should fix that.
