iOS 14 crash #23

Closed arthur-ver closed 3 years ago

arthur-ver commented 3 years ago

CodeScanner sometimes crashes with the error "Thread 1: "*** -[__NSSingleObjectArrayI objectAtIndex:]: index 1 beyond bounds [0 .. 0]"

arthur-ver commented 3 years ago

Nevermind. It was an issue with self.presentationMode.wrappedValue.dismiss() when using multiple Views inside .sheet

arthur-ver commented 3 years ago

Ok, it has still not fixed the issue...

I have experienced the same issue!

Hello, to complement the error I see that it occurs when the user rejects the camera permission. This is what generates the error log:

It seems to be very similar to #18.

TusharSharma651 commented 3 years ago

Happening on this line of code. let previewConnection = captureSession.connections[1]

jzeisweiss commented 3 years ago

I found the same issue as @TusharSharma651 where it can crash if you quickly launch the view controller for line 180 of ScannerViewController.

@twostraws - This issue has been fixed by https://github.com/twostraws/CodeScanner/pull/10. Can you tag a new release?

twostraws commented 3 years ago

@jzeisweiss Done!
