I have a simple view controller which is being rendered modally simply by using

viewController.present(myVC, animated: true, completion: nil)

myVC view controller does not have any embedded navigation controller and in viewDidLoad of myVC I am setting view which is supposed to behave like navigation bar view (I can't use navigation bar / navigation controller unfortunately)

Here is how I add the view programmatically

 self.view.addSubview(topView)
 topView.translatesAutoresizingMaskIntoConstraints = false
 topView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor).isActive = true
 topView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor).isActive = true
 topView.topAnchor.constraint(equalTo: self.topLayoutGuide.bottomAnchor).isActive = true
 topView.heightAnchor.constraint(equalToConstant: 70).isActive = true

I have specified extended edges as top in my viewDidLoad of myVC

self.edgesForExtendedLayout = .top

And the UI looks like

There is a gap between status bar and view added highlighted by yellow border which I am not sure how to fix :(

Please help

You get the gap because you are adding your topView's top constraint to the view's topLayoutGuide.bottom (which sits a bit below the notch). So that is intended behavior.

The cleanest way to get rid of that gap is to embed you view controller in a UINavigationController and use a real navigation bar.

But if you cannot do that you have to get rid of the gap yourself.

I cannot think of an elegant way to get rid of this gap but you could add a negative constant to the constraint that is as high as the gap:

topView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: -14).isActive = true

But you would have to make sure that this is only done on devices that have a safeAreaLayoutGuide.topAnchor > 0. (iPhoneX etc.). On all other devices the constant has to be 0.

As I said this is not a very stable or elegant solution but it would work.

BTW If possible you should change self.topLayoutGuide.bottomAnchor (deprecated) to view.safeAreaLayoutGuide.topAnchor.
