NSTemporaryExceptionAllowsInsecureHTTPLoads not working

NSExceptionAllowsInsecureHTTPLoads

1. Starting with Xcode 11.3, I created a new iOS test project.

2. I added this code to the project:

   NSLog("task will start") let url = URL(string: "http://m.tata-daewoo.com/")! let request = URLRequest(url: url, cachePolicy: .reloadIgnoringLocalCacheData, timeoutInterval: 60.0) URLSession.shared.dataTask(with: request) { (data, response, error) in     if let error = error as NSError? {         NSLog("task transport error %@ / %d", error.domain, error.code)         return     }     let response = response as! HTTPURLResponse     let data = data!     NSLog("task finished with status %d, bytes %d", response.statusCode, data.count) }.resume()

   .

3. On the iOS 13.3 simulator [1], this is blocked by ATS.

4. I added the following ATS dictionary to the app.

   <key>NSAppTransportSecurity</key>
   <dict>
       <key>NSExceptionDomains</key>
       <dict>
           <key>m.tata-daewoo.com</key>
           <dict>
               <key>NSExceptionAllowsInsecureHTTPLoads</key>
               <true/>
           </dict>
       </dict>
   </dict>

   .

5. Retesting, it works just fine:

   2020-01-31 08:42:09.234545+0000 xxsi[39472:704817] task will start
   2020-01-31 08:42:10.245609+0000 xxsi[39472:705001] task finished with status 200, bytes 3988

   .

Please repeat my test to confirm that it’s working in your environment. If so, you should look at the differences between your test and mine to see if you can work out why your test is failing.

[1] My experience is that the simulator is very accurate when it comes to ATS issues.

Hi,

Thanks for your reply.

The code in step 2, where should I add it in my project?

Also FYI I'm using iOS simulator v11.2.1.

The code in step 2, where should I add it in my project?

Ah, um, you don’t need to add my code to your project; I presume you already have code that talks to your server. I posted my code to show how I tested it.
