title: Itunes app links are not working with WkWebview
body: <p>One of the webpage I load into Wkwebview has the following iTunes app link</p>
  
  <pre><code> https://itunes.apple.com/gb/app/xx-yy-zz/id435919263?mt=8
  </code></pre>
  
  <p>when it's opened I'm getting the following alert</p>
  
  <p><a href="https://i.stack.imgur.com/RZATj.png" rel="noreferrer"><img src="https://i.stack.imgur.com/RZATj.png" alt="enter image description here"></a></p>
  
  <p>and here's the error that I've got.</p>
  
  <pre><code>{
      "[errorCode]" = 0;
      "[errorDescription]" = "Redirection to URL with a scheme that is not HTTP(S)";
      "[errordetail]" = "Con:myappxxxx:myorder:webview:networkerror";
      "[localizedRecoverySuggestion]" = "";
      "[url]" = "itms-appss://apps.apple.com/gb/app/xx-yy-zz/id435919263";
  }
  </code></pre>
  
  <p>When the same iTunes link ( <a href="https://itunes.apple.com/gb/app/xx-yy-zz/id435919263?mt=8" rel="noreferrer">https://itunes.apple.com/gb/app/xx-yy-zz/id435919263?mt=8</a> )
   is opened in UIWebview , I saw that URL gets redirected to following URL and app opens in appstore</p>
  
  <pre><code> itms-appss://itunes.apple.com/gb/app/xx-yy-zz/id435919263?mt=8
  </code></pre>
  
  <p>Whereas in Wkwebview , the URL gets redirected to following URL</p>
  
  <pre><code> itms-appss://apps.apple.com/gb/app/xx-yy-zz/id435919263
  </code></pre>
  
  <p>Any help is appreciated</p>

  <p>Update</p>
  
  <p>I even tried Arbitrary uploads to true for transport security and the problem is still there.</p>
