2015-09-18 22:04:56.167 MyBlogReader[16021:2088814] App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file. 2015-09-18 22:04:56.178 MyBlogReader[16021:2088731] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'data parameter is nil'

I have looked around online for a solution to this. Forums are stating that I need to edit the Info.plist. Is this correct? I don't know how to access the source code of this file, I only see autofill options.

Add this line to your Info.plist file alt text click the + symbol to add the new item "NSAppTransportSecurity" and set its type to 'dictionary'. Then select the new line and click the + symbol to add the "NSAllowsArbitraryLoads" into the NSAppTransportSecurity dictionary.

I don't see NSAppTransportSecurity in Info.plist. IOS9 removed it?

Note that the given answers are discouraged. Because setting NSAllowsArbitraryLoads to true will allow all insecure (http://) connections opening your app to threats. See the answers on Stackoverflow for more information.. Basically what the answers says is make an exception for each domain you want to allow with the following XML-Code inside your info.plist file.

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>yourserver.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>

To see and edit the source code of the info.plist file choose right click -> 'Open As' -> 'Source Code' in your project navigator.

Awesome, this fixed the issue. Thank you so much Pablo! (I watched the entire WWDC video on this and still couldn't make it work. )

I just noticed your second comment. If you click on the "+" on any item, you can manually add an item to the Info.plist and the then type in specifications you listed about. These items do not autocomplete; however, once you add it in the request works.

I have the same issue that I can't find NSAppTransportSecurity in iOS9 info.plist. try to find some website as reference like http://stackoverflow.com/questions/30731785/how-do-i-load-an-http-url-with-app-transport-security-enabled-in-ios-9 but still can't fix the problem.

Thanks Simon a lot! Finally solve this problem :)

Under the project navigator, right click "Info.plist" > Open as > Source code. Then, copy this:

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

Paste it in with the other keys.

Right click "Info.plist" > Open as > Property list. You should see that NSAppTransportSecurity is effectively disabled for this project.
