Crash on iPad when sharing images


I am using the Fabric TwitterKit to display the twitter feed of a particular user. To this end I am using the Methodology described here: Show Timeline - Fabric iOS

The issue occurs when I tap on an image in a tweet. I am navigated to the image screen. When I tap on the share button on this screen, the app crashed with the following message

*** Terminating app due to uncaught exception 'NSGenericException', reason: 'UIPopoverPresentationController (<_UIAlertControllerActionSheetRegularPresentationController: 0x7fe195f13380>) should have a non-nil sourceView or barButtonItem set before the presentation occurs.'

This issue is apparently fixed ( Share Tweet crashes on ipad iOS 8.3 ), but I am using TwitterKit v1.15

Would appreciate any help.

Thanks in advance.
