title: How to make user defined runtime attribute functioned in xcode 10.2.1 and ios 12.2
body: <p>I'm converting the codes to Swift 5 since Xcode 10.2.1 will no longer support Swift 3.</p>
  
  <p>I have an user-defined runtime variables in storyboard. It was worked in Swift 3 but not in Swift 5.</p>
  
  <blockquote>
    <p>Key Path | Type | Value<br>
    type | String | A</p>
  </blockquote>
  
  <pre><code>class Mains: UITableViewController, XMLParserDelegate {
    ...    
    var type = String()
    ...
  
    func loadBuses(){
  
      let url:String="http://example.com/Main.php?type="+type
      let urlToSend: URL = URL(string: url)!
      ...
    }
  
    ...
  }
  </code></pre>
  
  <p>In Swift 3, it was functioned and url return "<a href="http://example.com/Main.php?type=A" rel="nofollow noreferrer">http://example.com/Main.php?type=A</a>". 
  But in Swift 5, actual output of url just return "<a href="http://example.com/Main.php?type=" rel="nofollow noreferrer">http://example.com/Main.php?type=</a>".</p>
  
  <p>In there any alternatives which I can still use user-defined runtime attributes in storyboard for the class? Thank you.</p>
