How can I add NSAppTransportSecurity to my info.plist file?

Question

https://developer.apple.com/videos/wwdc/2015/?id=711 @5:55

I can't seem to be able to add this to my info.plist. There is no value it. I'm running XCode Version 7.0 beta (7A121l), and testing on iOS9.

Because I can't specifically declare what URL's I want as seen in the video, I keep getting "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" errors.

However, I don't seem to be able to configure it. Any ideas?

Answer 1

try With this --- worked for me in Xcode-beta 4 7.0

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

Also one more option, if you want to disable ATS you can use this :

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

But this is not recommended at all. The server should have the SSL certificates and so that there is no privacy leaks.

Answer 2

You have to add just the NSAllowsArbitraryLoads key to YES in NSAppTransportSecurity dictionary in your info.plist file.

For example,

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

Answer 3

That wasn't working for me, but this did the trick:

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

Answer 4

Just to clarify ... You should always use httpS

But you can bypass it adding the exception:

Answer 5

Xcode 8.2, iOS 10

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

Answer 6

Update Answer (after wwdc 2016):

IOS apps will require secure HTTPS connections by the end of 2016

App Transport Security, or ATS, is a feature that Apple introduced in iOS 9. When ATS is enabled, it forces an app to connect to web services over an HTTPS connection rather than non secure HTTP.

However, developers can still switch ATS off and allow their apps to send data over an HTTP connection as mentioned in above answers. At the end of 2016, Apple will make ATS mandatory for all developers who hope to submit their apps to the App Store. link

Answer 7

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>com</key>
        <dict>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
        <key>net</key>
        <dict>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
        <key>org</key>
        <dict>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
    </dict>
</dict>

This will allow to connect to .com .net .org

Answer 8

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>
            <key>uservoice.com</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSExceptionRequiresForwardSecrecy</key>
                <false/>
            </dict>
        </dict>
    </dict>

Answer 9

To explain a bit more about ParaSara's answer: App Transport security will become mandatory and trying to turn it off may get your app rejected.

As a developer, you can turn App Transport security off if your networking code doesn't work with it, and you want to continue other development before fixing any problems. Say in a team of five, four can continue working on other things while one fixes all the problems. You can also turn App Transport security off as a debugging tool if you have networking problems and you want to check if they are caused by App Transport security. As soon as you know you should turn it on again immediately.

The solution that you must use in the future is not to use http at all, unless you use a third party server that doesn't support https. If your own server doesn't support https, Apple will have a problem with that. Even with third party servers, I wouldn't bet that Apple accepts it.

Same with the various checks for server security. At some point Apple will only accept justifiable exceptions.

But mostly, consider this: You are endangering the privacy of your customers. That's a big no-no in my book. Don't do that. Fix your code, don't ask for permission to run unsafe code.

Answer 10

One bad news for developers using NSAppTransportSecurity.

UPDATE:
[Apple will require HTTPS connections for iOS apps by the end of 2016]

https://techcrunch.com/2016/06/14/apple-will-require-https-connections-for-ios-apps-by-the-end-of-2016/

Answer 11

In mac shell command line , use the following command:

plutil -insert NSAppTransportSecurity -xml "<array><string> hidden </string></array>" [location of your xcode project]/Info.plist 

The command will add all the necessary values into your plist file.

Answer 12

XCODE 8, Swift 3: You need to add a row: **

"App transport Security Setting"

** in the info.plist inside information Property list.

Answer 13

Xcode 9.2, Swift 4, this works for me.

<key>App Transport Security Settings</key>
<dict>
    <key>Allow Arbitrary Loads</key>
    <true/>
</dict>

Answer 14

Open your info.plist file of your project with any editor of your preference, then add this code at the end of the file before the last

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