Fatal error with: bannerPositionFrame.startFrame

[EdwinJr13]

When I try to display the notification on a real device it shows that error:

Thread 1: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value

On this line:

self.frame = bannerPositionFrame.startFrame

Help please.

Have the same issue. I use the Banner from SwiftUI so I don't pass the UIViewController, banner shows on the main window.

[gavrilaf]

I found my case reason. The application tries to show banner when a user cancels Google/Fb authentification, so the current scene has foreground inactive state and NotificationBanner couldn't retrieve the window.

It happens here:

if #available(iOS 13.0, *) {
            return UIApplication.shared.connectedScenes
                .first { $0.activationState == .foregroundActive }
                .map { $0 as? UIWindowScene }
                .map { $0?.windows.first } ?? UIApplication.shared.delegate?.window ?? nil
        }

Dirty workaround - show notification with delay. Or add support for pending notifications and show notifications depends on application state. But it isn't the question for the library.
