Added pixate framework.
Updated the storyboard to mimic the original project (yeay I know, I'm not the designer, some UX/UI/whatever expert is)
Managed to reproduce in these step

1) Tap TabBarItem 2
2) Tap TabBarItem 1
3) Scroll upp and down a bit

4) You should not see TableView assertion regarding the indexPath.

This does not happen with Pixate 2.0.1
