title: Code formatting in Swift to use the UIAccessibilityRequestGuidedAccessSession function
body: <p>I'm new to Swift code formatting and I'm trying to figure out how to use the UIAccessibilityRequestGuidedAccess function.  Here's how the function is declared in Swift:</p>
  
  <pre><code>func UIAccessibilityRequestGuidedAccessSession(_ enable: Bool,
                                           _ completionHandler: ((Bool) -&gt; Void)!)
  </code></pre>
  
  <p>In Objective-C I would have used it as follows:</p>
  
  <pre><code>UIAccessibilityRequestGuidedAccessSession(YES, ^(BOOL didSucceed) {
          if (didSucceed ) {
              ...
          } else {
              ...
          }
  </code></pre>
  
  <p>Any help with the syntax is appreciated.</p>
