I have found the answer here: What is causing NSNull length unrecognized selector keyCommand error

Basically somewhere in your navigation stack there is a storyboard that has these lines

  <keyCommands>
          <keyCommand/>
  </keyCommands>

Open your storyboard in text editor and search for that. Note that it may be not in the storyboard/scene that is causing crash, but in any scene used in navigation stack.
