Found solution:

In iOS9, ATS enforces best practices during network calls, including the use of HTTPS.

<a href="https://developer.apple.com/library/prerelease/ios/releasenotes/General/WhatsNewIniOS/Articles/iOS9.html" rel="noreferrer">From Apple documentation:</a>

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:

<pre><code>&lt;key&gt;NSAppTransportSecurity&lt;/key&gt;
&lt;dict&gt;
 &lt;key&gt;NSAllowsArbitraryLoads&lt;/key&gt;
 &lt;true/&gt;
&lt;/dict&gt;
</code></pre>

<img src="https://i.stack.imgur.com/nGw3j.png" alt="enter image description here">

Update1: This is a temporary workaround until you're ready to adopt iOS9 ATS support. 

Update2: For more details please refer following link:
<a href="http://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/" rel="noreferrer">http://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/</a>

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

<pre><code>&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;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;

How to deal with the SSL in iOS9，One solution is to do like:

As the <a href="https://developer.apple.com/library/prerelease/ios/releasenotes/General/WhatsNewIniOS/Articles/iOS9.html#//apple_ref/doc/uid/TP40016198-DontLinkElementID_13">Apple</a> say :
 <img src="https://i.imgur.com/eTgSHZY.png" alt="enter image description here">
 <img src="https://i.imgur.com/Tc0fS6p.jpg" alt="enter image description here">

<img src="https://i.imgur.com/v2Tskwh.jpg" alt="enter image description here">

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:

<pre><code>&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;
</code></pre>

If your application (a third-party web browser, for instance) needs to connect to arbitrary hosts, you can configure it like this:

<pre><code>&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;
</code></pre>

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.

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 <code>NSExceptionRequiresForwardSecrecy</code> to enable another handful of ciphers that S3 uses.

In our <code>Info.plist</code>:

<pre><code>&lt;key&gt;NSAppTransportSecurity&lt;/key&gt;
&lt;dict&gt;
 &lt;key&gt;NSExceptionDomains&lt;/key&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.

Update: 

As of Xcode 7.1, you don't need to manually enter the <code>NSAppTransportSecurity</code> Dictionary in the <code>info.plist</code>.

It will now autocomplete for you, realize it's a dictionary, and then autocomplete the <code>Allows Arbitrary</code> Loads as well.

You should add <code>App Transport Security Settings</code> to <code>info.plist</code> and add <code>Allow Arbitrary Loads</code> to <code>App Transport Security Settings</code> 

<a href="https://i.stack.imgur.com/mFIvd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mFIvd.png" alt="enter image description here"></a>

<pre><code>&lt;key&gt;NSAppTransportSecurity&lt;/key&gt;
 &lt;dict&gt;
 &lt;key&gt;NSAllowsArbitraryLoads&lt;/key&gt;
 &lt;true/&gt;
 &lt;/dict&gt;
</code></pre>

Tried to run my existing app on iOS9 but getting failure while using <code>AFURLSessionManager</code>.

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

 } else {

 }
}];

[task resume];
</code></pre>

I get the following error:

<pre><code>Error Domain=NSURLErrorDomain Code=-999 "cancelled.
</code></pre>

Also getting following logs: 

<pre><code> NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9824
 CFNetwork SSLHandshake failed (-9824)
</code></pre>

Update:
I have added multiple updates to my solution:
