I want to draw the background image on my own, so I decided to implement a UIImageView class and connect it in the Storyboard. As first task I just want to set the backgroundcolor of the image on my own, but it's never shown. Image just stays blank.

That's the class:

class FirstBackgroundImage : UIImageView {

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    self.backgroundColor = UIColor.redColor()

}

override init() {
    super.init()
    self.backgroundColor = UIColor.redColor()
}

override required init(image: UIImage!) {
    super.init(image: image)
    self.backgroundColor = UIColor.redColor()
}

}

That's how i connected it:
