Getting black screen except navigation Bar SWIFT

Question

My all previous projects works fine with this simulator but now whenever i'm creating new ViewController in previous projects or in new project, then ViewController looks black except Nav Bar. I don't know what's the problem even i reset my simulator but nothing solve my problem,

i think this problem seem to be so complicated.

import UIKit

class ViewController: UINavigationController {

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}



}

Currently View Controller looks here

ScreenShot attached here 1 and 2

I will be very glad if any of them help me.

Thanks

How are you configuring navigation bar? Where? In storyboard? If yes - can you provide screenshots of your storyboard? — Ivan Smetanin, May 26 '18 at 19:51
@IvanSmetanin updated my question, as i have do nothing with my View controller — Ahtazaz, May 26 '18 at 19:59
This is UINavigationController, where is view controller code — Jogendar Choudhary, May 26 '18 at 20:06
Have you added root view controller or initial view controller — Jogendar Choudhary, May 26 '18 at 20:06
This is a UINavigationController, not a UIViewController So you need to embed UIViewController with this UINavigationController — Jogendar Choudhary, May 26 '18 at 20:17
To put it another way, this line is wrong: `class ViewController: UINavigationController` There is _never_ a good reason to subclass UINavigationController. — matt, May 26 '18 at 20:22

It's because you are using UINavigationController as superclass of your ViewController. You can change superclass to UIViewController and embed your ViewController in UINavigationController.

Updated code:

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

This is a UINavigationController, not a UIViewController So you need to embed UIViewController with this UINavigationController. That's why you are getting the black screen.

You need to embed UIViewController with this navigation controller.
