When I try to present the ViewController using code

PreMIBlurPopup.show(popupViewController, on: self), it gives me an error

Fatal error: Unexpectedly found nil while unwrapping an Optional value

I create my popup view controller as a separately with a xib file for reusability. It only contains an image view.

import UIKit
import MIBlurPopup

class PopupViewController: UIViewController {
    @IBOutlet weak var imageView: UIImageView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        modalPresentationCapturesStatusBarAppearance = true
    }
    
    @IBAction func didTapdismissButton(_ sender: UIButton) {
        dismiss(animated: true)
    }
    
}

// MARK: - MIBlurPopupDelegate
extension PopupViewController: MIBlurPopupDelegate {
    var popupView: UIView {
        return UIView()
    }
    
    var blurEffectStyle: UIBlurEffectStyle {
        return .dark
    }
    
    var initialScaleAmmount: CGFloat {
        return 0.7
    }
    
    var animationDuration: TimeInterval {
        return 0.3
    }
}

Then I show it like this.

let popupViewController = PopupViewController()
MIBlurPopup.show(popupViewController, on: self)

But it looks like this when displayed.

The image view is supposed to have a margin of 20 from the trailing side too. But it seems to be ignoring the auto layout constraints. I can't figure out what's wrong.

I uploaded a demo project here.

I am setting up a popover to be presented like this:

let detailVC = storyboard?.instantiateViewController(withIdentifier: "Detail") as! DetailViewController     
let navController = UINavigationController(rootViewController: detailVC)

navController.modalPresentationStyle = .popover
        
navController.popoverPresentationController?.sourceView = self.view
        
 navController.popoverPresentationController?.delegate = self as? UIPopoverPresentationControllerDelegate
        
navController.popoverPresentationController?.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
        
 navController.preferredContentSize = CGSize(width: 450, height: 700)
        
 navController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
        
 popoverPresentationController?.passthroughViews = nil

I am trying to present it like this:

MIBlurPopup.show(navController, on: self)

My detailViewController conforms to the MIBlurDelegate but the nav controller doesnt. Is there a way for MIBlur to present a navigation controller? I would like my popover to be embedded in a nav controller.

Hi Mario, great library here, it makes the blurred background effect really easy! I'm wondering if it's possible for it to work with a navigation tab bar controller?

I couldn't get it to work by changing the modalPresentationStyle to .full

When setting a custom width and height for the container view in the Regular width and height size class, and pinning the sides to the top, bottom, let and right in the compact size class, things get a bit weird.

The height constraints are completely ignored.

can you add support for UINvavigationController() right now i believe only UIVIewcontrollers will show. I know i can add my own Navigation bar but adding a custom one does not have the same behavior as the default Navigation controller.

It's really a nice 3rdParty u made. I have a question,I have a tableview within tabbar controller. then after tableview didSelectRowAt func called. will popup the blure view. However the first time to click the cell, it works fine. but if I click other cells it will show up after quite a long time, or if I click the cell again ,then it show up. how can I fix this issue? Thank u

Thanks for the MIBlurPopup. I have a little problem. When showing the popup, tabbar shows up and I am unable to hide it in popupbar view controller too.
