title: Xcode 9.4.1 Could not build module and redefinition of module - Can't Build

  <p>Encountering this issue in Xcode, solutions I've tried:</p>
  
  <ul>
  <li>Enabled modules to <strong>YES</strong> and <strong>NO</strong></li>
  <li>Reinstalled Xcode 9.4.1 by deleting 9.4.1 and <code>~/Library/Developer</code></li>
  <li>Downgraded command lines tools to 9.4.1</li>
  <li>Downgraded Cocoapods to 1.4.0 from 1.5.3</li>
  </ul>
  
  <p>I'm at a loss at this point can someone point me to the right direction here? I've already spent an entire day on this. Other projects build fine though. </p>
