UITableView layout messing up on push segue and return. (iOS 8, Xcode beta 5, Swift)

Question

tldr; Auto constrains appear to break on push segue and return to view for custom cells

Edit: I have provided a github example proj

Answer 1

In xcode 6 final for me the workaround does not work. I am using custom cells and dequeing a cell in heightForCell leads to infinity loop. As dequeing a cell calls heightForCell.

And still the bug seems to be present.
