NSInvalidUnarchiveOperationException due to NSLayoutConstraint

Controller crash with the following error?

Terminating app due to uncaught exception ‘NSInvalidUnarchiveOperationException’, reason: NSLayoutConstraint

One quick solution::

  1. Open the .xib file of that controller.
  2. click on the view and go to file inspector in the right pane.
  3. deselect auto layout.
  4. build and run the application.

Works like a charm. 🙂
