Cheers is a highly customisable toast library for iOS written in Swift. It offers an alternate presentation style to the UIAlertViewController, by being displayed over the entire window and permitting interaction with other views while being presented.
When showing a toast which has isDismissable set to true there should be a dismiss button displayed so the user can end display of said toast.
Actual behaviour
The button does not show an image but still gets it's proper frame assigned, so users can technically dismiss the toast, they just will not know how to.
Solution
Something must have gone wrong while locating/setting the image, the problem will be resolved once a proper way to do so can be sorted out.
