Crashing in a Swift App

[aliirz]

Hi

I am using the logintoast inside a swift app. Here is my implementation:

Delegate:

class ViewController: UIViewController, SWBufferedToastDelegate {
...
}

Action to present and declare the toast:

@IBAction func loginAction(sender: AnyObject)  {

let toast = SWBufferedToast(loginToastWithTitle: "Login", usernameTitle: "Email", passwordTitle: "Password", doneTitle: "Login", backgroundColour: FlatGreen(), toastColor: UIColor.flatGreenColorDark(), animationImageNames: nil, andDelegate: self, onView: self.view)

        toast.appear()

}

Finally here are my delegate methods inside the same view controller:

//    SWBufferedToast Delegate methods

    func didAttemptLoginWithUsername(username: String!, andPassword password: String!, withToast toast: SWBufferedToast!) {



        toast.beginLoading()


    }

    func didTapActionButtonWithToast(toast: SWBufferedToast!) {
        print("button tapped")
    }

    func didDismissToastView(toast: SWBufferedToast!) {
        print("dismissed")
    }

The App crashes as soon as I hit the login button and call toast.beginLoading(). The stack trace of the crash is:

Dec  2 14:24:13  FlashFitPro[23654] <Error>: CGContextFillRects: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.
