Custom images NSRangeException when item selected

[Kml55]

Hi,

I want to use this library for custom image assets. It shows the assets but when an item is selected at index except zero, it gives exception like below.

Terminating app due to uncaught exception 'NSRangeException', reason: '0x600002899280: index (3) beyond bounds (1)'
terminating with uncaught exception of type NSException

I use library like below

private let images: [UIImage] = [ UIImage(named: "asset_x")!, UIImage(named: "y")!,UIImage(named: "close")!,UIImage(named: "assetname")!]

self.assetsPickerController = PickerViewController()
        self.assetsPickerController.delegate = self
        self.assetsPickerController.allowMultipleSelection = false
        self.assetsPickerController.images = images 

Is there a solution for this error?
