Custom UIView Background image

I'm using Swift for my project. Created a custom UIView class like the following:

class AppBgView: UIView {

    override init (frame : CGRect) {
        super.init(frame : frame)
        //self.isMemberOfClass(<#aClass: AnyClass#>)
    }

    convenience init () {
        self.init(frame:CGRect.zeroRect)
    }

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        self.backgroundColor = UIColor(patternImage: UIImage(named: "BGround.png")!)
    }
}

trying to set background image inside required init() method. But the background image doesn't seems to change. Any suggestion would be appreciated. Thanks.

SWIFT 5

 self.contentMode = UIView.ContentMode.scaleToFill
 self.layer.contents = UIImage(named:"bground.png")?.cgImage
 self.bringSubviewToFront(self)
 self.clipsToBounds = true

Finally I manage to solve it. replaced the self.backgroundColor = UIColor(patternImage: UIImage(named: "BGround.png")!) code with this one:

if let image = UIImage(named: "bground.png") {
    self.layer.backgroundColor = UIColor(patternImage: image).CGColor
}

The background image was added to the layer of that view. It works. Thanks everyone.

Put a breakpoint in each one of this methods and see which one of the constructors is being called. You will need to move the line 

self.backgroundColor = UIColor(patternImage: UIImage(named: "BGround.png")!)

To the constructor that being called.

In Swift A class must have at least one designated initializer. You may need to remove the word convenience from init().

Give this one a shot: UIColor(patternImage:UIImage(named: "BGround.png")!).CGColor
