title: iOS 13.1 PDFKit PDFView.go(to page:) isn't working
body: <p>The Apple API isn't working on iOS 13.1, does anyone have the same issue or I did wrong way to use it.</p>
  
  <p>I tried to get a PDFPage from PDFDocument.page(at: validPageIndex), the outcome page is with right index, and I set this page to PDFView.go(to: page) and the navigation isn't working.</p>
  
  <pre><code>let validPageIndex: Int = 11
  guard let targetPage = document.page(at: validPageIndex) else { return }
  print(targetPage.index)
  // Print 11
  pdfView.go(to: targetPage)
  </code></pre>
  
  <p>the line <code>pdfView.go(to: targetPage)</code> was executed but the page in PDF file stay at first page</p>
  
  <p>Thanks for Usama Azam, my PDFView display direction is horizontal, seems it works on vertical.</p>
