I just pushed a "fix", I don't know if it'll fix your problem. I need to see a bit of your code to know whether the problem comes from the lib.

[tpcmedia777]

didn't fixed it for me

Here is my Scanner code

class ScannerViewController: UIViewController, QRCodeReaderViewControllerDelegate {

var scannedtickets = [NSManagedObject]()
var alert = SCLAlertView()

let managedObjectContext = (UIApplication.sharedApplication().delegate as! AppDelegate).managedObjectContext

var frcontroller: NSFetchedResultsController = NSFetchedResultsController()

struct status : JSONJoy {
    var error: Bool?
    var message: String?
    init() {
    }
    init(_ decoder: JSONDecoder) {
        error = decoder["error"].bool
        message = decoder["message"].string
    }
}

private func contentView(text: String) -> UIView {
    let view = UIView(frame: CGRect(x: 0, y: 50, width: 375, height: 64))
    view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]


    let label = UILabel(frame: view.bounds)
    label.frame.origin.x = 10
    label.frame.origin.y = 10
    label.frame.size.width -= label.frame.origin.x
    label.frame.size.height -= label.frame.origin.y

    label.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
    label.text = text
    label.numberOfLines = 2
    label.textColor = UIColor.whiteColor()
    view.addSubview(label)

    return view
}


lazy var reader = QRCodeReaderViewController(metadataObjectTypes: [AVMetadataObjectTypeQRCode])

I show nothing special with that. If you try with a very small project without all this boilerplate, is the problem occured?

[tpcmedia777]

i'll take a look

[PabloLerma]

@tpcmedia777 It's been more than half a year here but the problem was with the
self.title = "Notification"
in one of your closures.
@yannickl I think we can close this issue.

[yannickl]

Yes you've right @PabloLerma! I didn't see this line. Thank you!
