Xcode 8: Cannot inherit from non-open class
<p>After I updated to latest Xcode 8, I get this error:</p>

<blockquote>
  <p>Cannot inherit from non-open class ‘WDBaseViewController’ outside of its defining module</p>
</blockquote>

<p>My class is declared like this</p>

<pre><code>public class ProfileViewController: WDBaseViewController {
}
</code></pre>

<p>But I didn’t change the framework.</p>
