I keep getting \'Unable to simultaneously satisfy constraints\' exceptions (Xcode 5, iOS 7, both device and simulator), where one of the constraints in the list is something

I found this with iOS 10 builds where I was using UITableViewCell subclasses as normal views not as table rows. The cell was constraining its contentView to zero width.

The workaround I used was to just add the contentView to the view hierarchy instead of the tableview cell. I also made sure to retain the tableView cell (as it was no longer being retained by the view hierarchy itself).
