title: Xcode storyboard class has no module
body: <p>I have a project with two targets A and B. </p>
  
  <p>When I open my storyboard and select one scene in particular and navigate to 'identity inspector' > 'custom class' > 'Module', </p>
  
  <p>there is a single blank entry in the drop down (the drop down does not display A or B). When I select the blank entry the drop down shows "None". This is a problem because it causes my program to crash when attempting to use the scene.  </p>
  
  <p>If I select 'Inherit module from target', the correct target displays under 'identity inspector' > 'custom class' > 'Module', however my program will still crash when attempting to use the scene. </p>
  
  <p>The class itself is found in the type-ahead of the 'identity inspector' > 'custom class' > 'Class' textbox.</p>
  
  <p>The name of the class is SWRevealController.m (which is an obj-c file) whereas most of my project is in swift.</p>
  
  <p>A and B appear as selectable in every other scene under 'identity inspector' > 'custom class' > Module. I can also select 'inherit module from target' for those scenes and the program does not crash.</p>
  
  <p>Other things I have tried:
  *manually deleting and re-adding the SWRevealController.m under 'Build Phases' > 'Compiled sources'
  *making a new storyboard and putting view controllers in from scratch. </p>
  
  <p>The main.storyboard itself is part of both targets.</p>
