Can not build in simulator on mac m1 device

How do you import the library?

Deadlock on QRCodeReaderView::setupComponents

Have you find a way to reproduce it?

create reader not in Main Thread

When do you call the readerVC? The `QRCodeViewController` doesn't instantiate UIKit components in background.

Example App crashes on iOS 10.0 - Thread 1: EXC_BAD_ACCESS (code=1, address=0x50)

I have no device with iOS10. Could someone help?

@artoymsd but you can't use the camera with the simulator? Have you checked the permissions and the camera availability before? ```swift try QRCodeReader.supportsMetadataObjectTypes() ```

QRCodeReader was compiled with optimization - stepping may behave oddly; variables may not be available.

In which case you have this warning (or error)?

metadataObjectTypes

This is a good idea, I'll add this option for a next release. :+1:

I want to stop camera after validation of QR code

Sorry I don't understand your use case. :/ You should call the `reader.stopScanning()` method to stop the camera.

Sorry I don't know Mandarin. Can you write in English please?

Exception: Array mutated while being enumerated

Very interesting. The only place where the `metadataObjectTypes` are mutating is during the initialisation. Maybe a race condition during the init workflow? Needs more investigation.
