I've updated to xcode7 and receive the following SSL error when running the sample code

2015-09-30 09:52:30.049 watsonsdktest[22866:520980] CFNetwork SSLHandshake failed (-9824) 2015-09-30 09:52:30.050 watsonsdktest[22866:520980] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9824)

This appears to be caused by the new TLS 1.2 requirements in ios9

It can be worked around with the method described here http://stackoverflow.com/questions/30720813/cfnetwork-sslhandshake-failed-ios-9 but needs fixing at the server side.

I added this to the application sample .plist which resolves the SSL error.

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>
            <key>watsonplatform.net</key>
            <dict>
                <!--Include to allow subdomains-->
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSTemporaryExceptionRequiresForwardSecrecy</key>
                <false/>
            </dict>
        </dict>
    </dict>

This needs a fix from the server side

Finally restored my iOS9 working environment and tried the app using the workaround above.

I can confirm that it is working for me on the simulator at least ( I'll try on hardware later )

Thanks for the workaround :)
