Hi, Is DataScannerViewController available to be called directly from Objective-C? I see the header file has an "objc" attribute on it, but trying to initialize it from an Objective-C file doesn't seem to be working for me. Maybe it's something I'm doing wrong, but I wanted to first clarify and confirm that if it indeed possible to use it directly in Objective-C, or not?

Hi, The presentation "Capture Machine Readable Codes and Text with VisionKit" mentions at the end that the DataScannerViewController can be used with an async stream. In the presentation, there is a code snipper for the updateViewAsyncStream method, but it's not really used anywhere. How do utilize this when the DataScannerViewController is active and capture the recognized items? Also there is a sendDidChangeNotification() function sat the end but the compiler complains that it's not in scope. Thanks.
