NSURLSession NSURLConnection HTTP load failed on iOS 9

Question

Tried to run my existing app on iOS9 but getting failure while using AFURLSessionManager.

__block NSURLSessionDataTask *task = [self.sessionManager dataTaskWithRequest:request completionHandler:^(NSURLResponse * __unused response, id responseObject, NSError *error) {
    if (error) {

    } else {

    }
}];

[task resume];

I get the following error:

Error Domain=NSURLErrorDomain Code=-999 "cancelled.

Also getting following logs:

 NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9824
 CFNetwork SSLHandshake failed (-9824)

Update: I have added multiple updates to my solution: NSURLSession/NSURLConnection HTTP load failed on iOS 9

Found solution   In iOS9  ATS enforces best practices during network calls  including the use of HTTPS   From Apple documentation   ATS prevents accidental disclosure  provides secure default behavior  and is easy to adopt  You should adopt ATS as soon as possible  regardless of whether you   re creating a new app or updating an existing one  If you   re developing a new app  you should use HTTPS exclusively  If you have an existing app  you should use HTTPS as much as you can right now  and create a plan for migrating the rest of your app as soon as possible   In beta 1  currently there is no way to define this in info plist  Solution is to add it manually    lt key gt NSAppTransportSecurity lt  key gt   lt dict gt       lt key gt NSAllowsArbitraryLoads lt  key gt       lt true  gt   lt  dict gt      Update1  This is a temporary workaround until you re ready to adopt iOS9 ATS support    Update2  For more details please refer following link  http   ste vn 2015 06 10 configuring-app-transport-security-ios-9-osx-10-11   Update3  If you are trying to connect to a host  YOURHOST COM  that only has TLS 1 0  Add these to your app s Info plist   lt key gt NSAppTransportSecurity lt  key gt   lt dict gt       lt key gt NSExceptionDomains lt  key gt       lt dict gt           lt key gt YOURHOST COM lt  key gt           lt dict gt               lt key gt NSIncludesSubdomains lt  key gt               lt true  gt               lt key gt NSTemporaryExceptionAllowsInsecureHTTPLoads lt  key gt               lt true  gt               lt key gt NSTemporaryExceptionMinimumTLSVersion lt  key gt               lt string gt 1 0 lt  string gt               lt key gt NSTemporaryExceptionRequiresForwardSecrecy lt  key gt               lt false  gt           lt  dict gt       lt  dict gt   lt  dict gt

Simply add the following fields in your .plist file

Syntax looks like this:

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

You should add App Transport Security Settings to info plist and add Allow Arbitrary Loads to App Transport Security Settings      lt key gt NSAppTransportSecurity lt  key gt       lt dict gt           lt key gt NSAllowsArbitraryLoads lt  key gt           lt true  gt       lt  dict gt

Update    As of Xcode 7 1  you don t need to manually enter the NSAppTransportSecurity Dictionary in the info plist   It will now autocomplete for you  realize it s a dictionary  and then autocomplete the Allows Arbitrary Loads as well   info plist screenshot

How to deal with the SSL in iOS9 One solution is to  do like   As the Apple say            iOS 9 and OSX 10 11 require TLSv1 2 SSL for all hosts you plan to request data from unless you specify exception domains in your app s Info plist file   The syntax for the Info plist configuration looks like this    lt key gt NSAppTransportSecurity lt  key gt   lt dict gt     lt key gt NSExceptionDomains lt  key gt     lt dict gt       lt key gt yourserver com lt  key gt       lt dict gt         lt  --Include to allow subdomains-- gt         lt key gt NSIncludesSubdomains lt  key gt         lt true  gt         lt  --Include to allow insecure HTTP requests-- gt         lt key gt NSTemporaryExceptionAllowsInsecureHTTPLoads lt  key gt         lt true  gt         lt  --Include to specify minimum TLS version-- gt         lt key gt NSTemporaryExceptionMinimumTLSVersion lt  key gt         lt string gt TLSv1 1 lt  string gt       lt  dict gt     lt  dict gt   lt  dict gt    If your application  a third-party web browser  for instance  needs to connect to arbitrary hosts  you can configure it like this    lt key gt NSAppTransportSecurity lt  key gt   lt dict gt       lt  --Connect to anything  this is probably BAD -- gt       lt key gt NSAllowsArbitraryLoads lt  key gt       lt true  gt   lt  dict gt    If you re having to do this  it s probably best to update your servers to use TLSv1 2 and SSL  if they re not already doing so  This should be considered a temporary workaround   As of today  the prerelease documentation makes no mention of any of these configuration options in any specific way  Once it does  I ll update the answer to link to the relevant documentation   For more info  go to iOS9AdaptationTips

Apple s Technote on App Transport Security is very handy  it helped us find a more secure solution to our issue   Hopefully this will help someone else  We were having issues connecting to Amazon S3 URLs that appeared to be perfectly valid  TLSv12 HTTPS URLs  Turns out we had to disable NSExceptionRequiresForwardSecrecy to enable another handful of ciphers that S3 uses   In our Info plist    lt key gt NSAppTransportSecurity lt  key gt   lt dict gt     lt key gt NSExceptionDomains lt  key gt     lt dict gt       lt key gt amazonaws com lt  key gt       lt dict gt         lt key gt NSIncludesSubdomains lt  key gt         lt true  gt         lt key gt NSExceptionRequiresForwardSecrecy lt  key gt         lt false  gt       lt  dict gt     lt  dict gt   lt  dict gt

I have solved it with adding some key in info.plist. The steps I followed are:

I Opened my project's info.plist file

Added a Key called NSAppTransportSecurity as a Dictionary.

Added a Subkey called NSAllowsArbitraryLoads as Boolean and set its value to YES as like following image. enter image description here

Clean the Project and Now Everything is Running fine as like before.

You can try add this function in file RCTHTTPRequestHandler.m

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler { completionHandler(NSURLSessionAuthChallengeUseCredential, [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]); }
