Adding subclass to Storyboard crashes

This is my class of a UIView:

class overlap: UIView{
    init() {
        super.init(frame: UIScreen.main.bounds)
    }
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        fatalError("init(coder:) has not been implemented")
    }
}

It should just fill up the screen. When I add the view in Storyboard with constraints pinned to the edges of the screen, it crashes when I launch the app. The error comes up as stated in the code above.

Creating and adding the subclass programmatically works with this init function:

override init(frame: CGRect) {
    super.init(frame: frame)
}

But I want it reusable through Storyboard, without adding code. What is wrong with my code, and is it even possible what I want?

Thanks!
