title: Accessing nested Swift enum in Objective-C
body: <p>I have a nested swift enum as following:</p>
  <pre class="lang-swift prettyprint-override"><code>@objc enum PARENT_ENUM: Int {    
      case test
          
      @objc enum CHILD_ENUM: Int{
          case CHILD_ENUM_CASE
      }        
  }
  </code></pre>
  <p>I want to access this enum in Objective-C. I tried the following in Objective-C:</p>
  <pre class="lang-objectivec prettyprint-override"><code>PARENT_ENUMTest; // This line is working.
  
  PARENT_ENUM.CHILD_ENUMCHILD_ENUM_CASE; // nested attempt giving error.
  
  PARENT_ENUM.CHILD_ENUM.CHILD_ENUM_CASE; // nested attempt giving error.
  </code></pre>
  <p>The compiler is giving the 'Expected identifier or '('' error.</p>
