After using BarcodeScannerController, iOS control panel flashlight icon gets disabled?

[jonchui]

REPRO STEPS:

1. open BarcodeScannerController
2. click the flash
3. leave the scanner
4. slide up on iOS control center

ACTUAL:
flashlight symbol is greyed out!

EXPECTED:
not greyed out

Code we use to call it:

let barcodeController = BarcodeScannerController()
        barcodeController.codeDelegate = self
        barcodeController.errorDelegate = self
        barcodeController.dismissalDelegate = self

 appDelegate = UIApplication.shared.delegate as! AppDelegate
            if UIDevice.current.orientation == UIDeviceOrientation.landscapeLeft {
                appDelegate.barCodeScannerOrientation = .landscapeRight
            } else {
                appDelegate.barCodeScannerOrientation = .landscapeLeft
            }
            
            barcodeController.reset()
            
            if let strongself = self {
            
                if AVCaptureDevice.authorizationStatus(forMediaType: AVMediaTypeVideo) ==  AVAuthorizationStatus.authorized {
                    // Already Authorized
                    strongself.present(barcodeController, animated: true, completion: nil)
                } else if AVCaptureDevice.authorizationStatus(forMediaType: AVMediaTypeVideo) ==  AVAuthorizationStatus.notDetermined {
                    AVCaptureDevice.requestAccess(forMediaType: AVMediaTypeVideo, completionHandler: { (granted: Bool) -> Void in
                        if granted == true {
                            // User granted
                            DispatchQueue.main.async {
                                strongself.present(barcodeController, animated: true, completion: nil)
                            }
                        }
                    })
                } else if AVCaptureDevice.authorizationStatus(forMediaType: AVMediaTypeVideo) ==  AVAuthorizationStatus.denied {
                    let alertController = UIAlertController(title: "Camera Access",
                                                            message: "The camera permission was not authorized. Please enable it in Settings to continue.",
                                                            preferredStyle: .alert)
                    
                    let settingsAction = UIAlertAction(title: "Settings", style: .default) { (alertAction) in
                        if let appSettings = NSURL(string: UIApplicationOpenSettingsURLString) {
                            UIApplication.shared.openURL(appSettings as URL)
                        }
                    }
                    alertController.addAction(settingsAction)
                    
                    let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
                    alertController.addAction(cancelAction)
                    
                    strongself.present(alertController, animated: true, completion: nil)
                }
            }

FIXED

Found that we were retaining the BarcodeScannerController b/c of the scope - moved it into the block and all was good.

Thanks!
