title: swift block selection of custom section header cell
body: <p>I have a UITableView with custom section headers, made via the storyboard using a custom prototype cell with a Identifier of "headerCell", along with a Cocoa Touch Class called "HeaderViewCell" subclassing UITableViewCell.</p>
  
  <pre><code>func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -&gt; UIView? {
      let headerCell = tableView.dequeueReusableCell(withIdentifier: "headerCell") as! HeaderViewCell
  
      headerCell.sectionTitle.text = viewModel.items[section].sectionTitle
      headerCell.section = section
      headerCell.delegate = self
  
      return headerCell
  }
  </code></pre>
  
  <p>The button in the cell fires a delegate func passing in the section that was assigned to it.</p>
  
  <p>Everything works great- setting the title, tapping the button I needed, etc... EXCEPT that when you tap the blank space between the section title (on the left) and button (on the right), the section header highlights as if it's a cell in the section, and then performs the segue for the first row in the section.</p>
  
  <p>Selection is set to "None" in the attributes inspector. If I toggle User Interaction Enabled, then the button does not work.</p>
  
  <p>I've found lots of posts where people are trying to register taps on the section headers (answer: with tap gestures), but exhausted myself in search of how to block them. In the didSelectRow at delegate method, I see the same IndexPath I would as if I clicked on the row and not the header, so I can't block it from there.</p>
  
  <p>Being that using a custom prototype cell is the most widely suggested response to a custom section header, I would have expected this to have been an issue for someone else as well. ?</p>
