What did you do?

    func showPopup() {
        
        let popup = PopupDialog(title: "title", message: "message", transitionStyle: .fadeIn, hideStatusBar: true)
        
        let buttonOne = DefaultButton(title: "close", action: nil)
        
        popup.addButtons([buttonOne])
        
        present(popup, animated: true, completion: nil)
    }

And laso adde:

    let ov = PopupDialogOverlayView.appearance()
    ov.blurEnabled     = true
    ov.blurRadius      = 30
    ov.liveBlurEnabled = true
    ov.opacity         = 0.7
    ov.color           = .black
    

What happened?

This issue happens when following Func is added (for presenting modal in iOS 13 fullscreen)

    override func present(_ viewControllerToPresent: UIViewController,
                          animated flag: Bool,
                          completion: (() -> Void)? = nil) {
        viewControllerToPresent.modalPresentationStyle = .fullScreen
        super.present(viewControllerToPresent, animated: flag, completion: completion)
    }

then show the PopupDialog with black background:

And if .fullScreen changes to .overFullScreen, the background Blur effect will disappear and just show Popup without any effect.

Also, I tested this issue with Example project in repo and got the same result.

I had the same problem. Turns out you have to set the view controller's modalPresentationStyle to ".overFullScreen". ov.modalPresentationStyle = .overFullScreen

See: Popup has black background even though it is set to clear
