TO JS undefined

[RyanYangGit]

When i run on ionic6, it doesn't work. The xcode output shows "TO JS undefined", no matter use BarcodeScanner.hideBackground() or BarcodeScanner.startScan(). Is anyone also got this error?

I have no issues in with my ionic 6 test setup, the plugin works as expected in my case so it might be an issues with your setup and not the plugin itself.

Can you share a repo where I can reproduce your issue?

I'm getting this too. When looking at Xcode I can see a warning:

discoverCaptureDevices()' is deprecated: New Xcode? Check if AVCaptureDevice.DeviceType has new types and add them accordingly.

Same here.

@ionic/vue v6.0.0 Capacitor v4.0.1 barcode-scanner v3.0.0

For me this was the issue. In @capacitor-community/barcode-scanner/ios/Plugin/Plugin.swift the UIApplication.shared.statusBarOrientation was not just deprecated, but is obsolete. This line:

self.videoPreviewLayer?.connection?.videoOrientation = interfaceOrientationToVideoOrientation(UIApplication.shared.statusBarOrientation)

should be replaced to something like this

if let interfaceOrientation = UIApplication.shared.windows.first(where: { $0.isKeyWindow })?.windowScene?.interfaceOrientation {
    self.videoPreviewLayer?.connection?.videoOrientation = interfaceOrientationToVideoOrientation(interfaceOrientation)
}

The TO JS undefined log remains, but the barcode scanner seems to work.
