    var rawParser: MBRawParser?

    func controller(transaction: OngoingTransaction, delegate: MBDocumentOverlayViewControllerDelegate) -> UIViewController? {
        MBMicroblinkSDK.sharedInstance().setLicenseKey("License we got goes here")
        let settings = MBDocumentOverlaySettings()
        rawParser = MBRawParser()
        parserGroupProcessor = MBParserGroupProcessor(parsers: [rawParser!])
        blinkInputRecognizer = MBBlinkInputRecognizer(processors: [parserGroupProcessor!])

        let recognizerList = [self.blinkInputRecognizer!]
        let recognizerCollection = MBRecognizerCollection(recognizers: recognizerList)

        /** Create your overlay view controller */
        let documentOverlayViewController = MBDocumentOverlayViewController(
            settings: settings,
            recognizerCollection: recognizerCollection,
            delegate: delegate)

        /** Create recognizer view controller with wanted overlay view controller */
        let recognizerRunnerViewController: UIViewController = MBViewControllerFactory.recognizerRunnerViewController(withOverlayViewController: documentOverlayViewController)

        return recognizerRunnerViewController
    }
}

The SDK was added to the project via CocoaPods like this:
pod 'PPBlinkID', '~> 4.10.0'

We run the app in both simulator and real device running iOS 12.4 and iOS 13 beta, the crash happens at: line 21 rawParser = MBRawParser(), I'm posting here the backtrace

    I also tried installing only this pod `pod 'MBBlinkCard', '~> 1.0.1'`, but the project does not compile
