title: Swift class does not conform to Objective-C protocol with error handling
body: <p>I have <code>Objective-C</code> Protocol</p>
  
  <pre><code>@protocol SomeObjCProtocol
  - (BOOL) doSomethingWithError: (NSError **)error;
  @end
  </code></pre>
  
  <p>And <code>Swift</code> class</p>
  
  <pre><code>class SwiftClass : SomeObjCProtocol
  {
      func doSomething() throws {    
      }
  }
  </code></pre>
  
  <p>Compilers gives me an <code>error</code></p>
  
  <blockquote>
    <p>Type 'SwiftClass' does not conform to protocol 'SomeObjCProtocol'"</p>
  </blockquote>
  
  <p>Is there any solution how to get rid of this error?
  I'm using <code>XCode 7 Beta 4</code></p>
