Multiple Errors, need help

[Bludyvenom]

First of all, after searching many websites and youtube videos, I'd finally got to know how to use that valueFormat option as nowhere it is mentioned in your library or in the official one or in any answer/question of StackOverflow. Even I got no answers on StackOverflow for the same.
But for now, four errors I've faced after handling many:

1. Camera View always looks compressed or distorted from sides and looks unnatural when compared to default camera app.
2. URL QR code does not work as code.url.url returns no value same as code.url.title (rawValue does the work here).
3. It is mentioned nowhere that how you can get the scanned barcode through the camera (takePicture()). Please provide that.
4. Gradle build error when updating to 2.0.3. I had to downgrade it to 2.0.0 as failed to resolve library is what I see every time.
   Please help.
