Need help in developing iOS/Swift

Question

I am newbie to iOS/Swift. I am developing app using Swift4 on XCode12. But I have a problem with presenting UIViewController.

Below is my code:

• presenting UIViewController

   let scanner = NewController({ ... }) scanner.delegate = self self.present(scanner, animated: true, completion: nil)

• NewController

  public class NewController: UIViewController, AVCaptureMetadataOutputObjectsDelegate { ... }

But it shows like this image. Image before/after presenting

As you can see in the image, it shows black margin after presenting NewController.

Anybody can help me?

I tested on simulator iPhone 8 (iOS 14.2).

This is the current UX that comes with presenting a View Controller modally. This is the expected output. If you want your view controller to take over the whole screen use pushViewController instead.

self.navigationController?.pushViewController(scanner, animated: true)

Use popViewController to dismiss your view controller.

self.navigationController?.popViewController(animated: true)
