contentInsetAdjustmentBehavior is never set

Question

I'm trying to set the contentInsetAdjustmentBehavior == .never for the UITableView in the viewDidLoad() of the ViewController, however it is ignored, no matter if I do it programmatically or via the InterfaceBuilder.

Here is what I get. The image is the header of the TableView.

I have the navigation bar on top of that which is transparent by the way.

I expect the Header with the image to be like this

Any help's appreciated. Thanks

Set the topConstraint constant of imageView to -64

• create an Outlet for topConstraint of imageView

• declare a variable topPadding (for iPhone X)

  @IBOutlet weak var topConstraint: NSLayoutConstraint!
  var topPadding:CGFloat = 0.0
  

And use the below code in viewDidload

override func viewDidLoad() {
    super.viewDidLoad()

    self.navigationController!.navigationBar.setBackgroundImage(UIImage(), for: .default)
    self.navigationController!.navigationBar.shadowImage = UIImage()
    self.navigationController!.navigationBar.isTranslucent = true
    topConstraint.constant = -64
    if #available(iOS 11.0, *) {
        let window = UIApplication.shared.keyWindow
        topPadding = (window?.safeAreaInsets.top)!
        topConstraint.constant = -(64+topPadding)
    }
}
