title: Definition conflicts with previous value in Swift 2.0
body: <p>I updated Xcode to version 7 and Swift 2.0. My application works and there are not any errors in Xcode 6 with Swift 1.2. I now get the error "Definition conflicts with previous value" in method <code>func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell</code> and I see Previous definition of '<code>tableView</code>' is here </p>
  
  <pre><code>override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
      if searchPredicate == nil  {
          return arrayItem.count ?? 0
      } else {
          return arrayFilterOfNames.count ?? 0
      }
  }
