UIViewController under UINavigationBar?

I have a UINavigationController and a UIViewController as its root view controller. 

let rootVC = Page1ViewController()   // extends UIViewController
let nav = UINavigationController(rootViewController: rootVC)
presentViewController(nav, animated: true) { () -> Void in
}

The problem is that the content of the rootVC appears under the navigation bar. I tried: 

nav.navigationBar.translucent = false

this worked but I want the navigation bar to be transparent and I want the content of the rootVC not appear behind the navigation bar.

I also tried: 

nav.edgesForExtendedLayout = UIRectEdge.None

but this does not change anything.

How can I get a transparent navigation bar where the content scrolls under it when scrolling but when loading the content should not appear under the navigation bar?

To address your issue of a blackbox now appearing underneath your UINavigationBar you need to set the presentation context properly. Try setting definesPresentationContext on your UINavigationController to NO. This will then use the UIWindow or parent of your UINavigationController as the presentation context.

Remove this line: 

nav.edgesForExtendedLayout = UIRectEdge.None

And add this line in your viewDidLoad from Page1ViewController 

self.edgesForExtendedLayout = UIRectEdge.None

Hope it helps. Let me know if it doesn´t work and I will help you.
