Arrow not showing

[ogezue]

Here is how I use your lib:

 private func showPopup(){
        
        let controller = PopoverController(items: popoverOptions(), fromView: stateImageView, direction: .up, style: .withImage)
        controller.coverColor = UIColor.darkGray
        controller.textColor = UIColor.white
        popover(controller)
    }

Unfortunately the error doesn't show up. Any idea what causes this? I'm using 3.0.1
