How do I load an HTTPS URL in iOS 9?

Question

What setting do I need to put in my info.plist to enable HTTPS mode? I've already put this in my plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

But it's not working, I'm still getting this error

Error Message:-

UPDATE: Better update your server to support SSL and TLSv1.2

Use this for temporary use only. This method isn't totally advisable:

   <key>NSAppTransportSecurity</key>
<dict>
    <!--Connect to anything. Not advisable. For desperate measures I guess-->
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

Original Answer:

iOS 9 supports TLSv1.2, see this document. So by changing it to TLSv1.1, it bypasses the security (which is not that completely advisable). Also, specify your url like this:

 <key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>enterYourUrlHere.com</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Include to allow HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Include to specify minimum TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
</dict>
