iOS swift how to place an imageview in a uiview exactly

I have an issue, I'm creating an imageView programmatically and then add it to a center view, which is kind of working. But the problem is that is not taking the whole space in the center view, it appears yes in the uiview but not covering all always a bit down. Any help?

The code:

//let backgroundImage = UIImageView(frame: centerView.frame)
            let backgroundImage: UIImageView = UIImageView(frame: CGRect(x: 0, y: 0, width: self.centerView.bounds.size.width, height: self.centerView.bounds.size.height))
            print("backgorundImage coordinates: \(backgroundImage.frame)")
            backgroundImage.image = drawOverImage
            backgroundImage.sizeThatFits(CGSizeMake(centerView.bounds.width, self.centerView.bounds.height))
            //check this the image is being drawn bottom because is the fame for the previous 0.0
            //backgroundImage.autoPinEdgeToSuperviewMargin(ALEdge.Top, relation: NSLayoutRelation.Equal)
            //backgroundImage.contentMode =  UIViewContentMode.ScaleAspectFill //too big
            //backgroundImage.contentMode = UIViewContentMode.ScaleAspectFit     //sama
            backgroundImage.contentMode = UIViewContentMode.ScaleAspectFill
            backgroundImage.clipsToBounds = true
            //imageView.image = background
            backgroundImage.center = view.center

            let coordinatesForImage: CGRect = self.view.convertRect(backgroundImage.frame, toView: centerView)
            let pointOfImage: CGPoint = backgroundImage.convertPoint(self.centerView.frame.origin, toView: backgroundImage)

            print("coordinates test: \(coordinatesForImage)")
            print("point x: \(pointOfImage.x)")
            print("point y: \(pointOfImage.y)")

            //backgroundImage.contentMode = UIViewContentMode.ScaleToFill
            self.centerView.insertSubview(backgroundImage, atIndex: 0)


            let pointOfImageToSuperView: CGPoint = (backgroundImage.superview?.convertPoint(backgroundImage.center, toView: self.centerView))!

            print("superview imagepoint: \(pointOfImageToSuperView)")

The comments are all the thing I'm trying to do.

EDIT: This is what is happening.

Missing bottom

I missing a little bit from the bottom, now I don't know if is the size of the image or what, could i change the size of the uiview to match the image?

Simply try:

let backgroundImage: UIImageView = UIImageView(frame: self.centerView.bounds)
backgroundImage.clipsToBounds = true
backgroundImage.contentMode = .ScaleAspectFill
self.centerView.addSubview(backgroundImage)
