ZXing Xamarin Forms iOS white background (without Custom Renderer)

I have implemented the ZXing.Xamarin.Mobile.Forms QR scanner(Nuget package) with custom overlay.

In Android it is working nicely, but in iOS I'm getting no scanner and a white background.

The package is added to the iOS project as well.

Has anyone experienced this?

I know how to program it using Custom Renderers so I'm not interested in answers regarding this.

Solution

Have you added the init() in your AppDelegate and MainActivity ?
