title: dyld: Library not loaded error in Swift - IQKeyboardManagerSwift
body: <p>My app has been building and testing successfully on my iPhone since I began development.</p>
  
  <p>It just started failing to build within the simulator; a Clean Build Folder fixed the simulator, but now when building on my phone I get:</p>
  
  <blockquote>
  <pre><code>  Referenced from: /private/var/containers/Bundle/Application/89F8B333-855C-4DE8-8A6A-E2472EF176DA/MyApp.app/MyApp

  </code></pre>

  <p>This is out of the blue; I've not done anything to the keyboard library, I've not added any new libraries.</p>
