Disable App Transport Security in iOS 9

info.plist

<!--
This disables app transport security and allows non-HTTPS requests.
Note: it is not recommended to use non-HTTPS requests for sensitive data. A better
approach is to fix the non-secure resources. However, this patch will work in a pinch.

To apply the fix in your Ionic/Cordova app, edit the file located here:

platforms/ios/MyApp/MyApp-Info.plist

And add this XML right before the end of the file inside of the last </dict> entry:
   
    PASTE HERE
  </dict>
</plist>

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