iOS9 GoogleAnalytics and NSAppTransportSecurity

Actually the above configuration was slightly wrong, I found a working approach.

-- Short story start --

Basically, the above approach was mostly correct, but I came up to check the configuration again, when I had a look at the established network connection from Mac OS 10.10 and OS 10.11

openssl s_client -connect ssl.google-analytics.com:443 -status

Mac OS 10.10 made use of TLSv1.2, while Mac OS 10.11 for whatever reason used TLSv1.0

-- Short story end --

So, after rethinking the attributes, I removed the Certificate transparency NSRequiresCertificateTransparency, as the default is also set to be false and not true. The following configuration now works for me:

<key>NSAppTransportSecurity</key>    <dict>        <key>NSAllowsArbitraryLoads</key>        <false/>        <key>NSExceptionDomains</key>        <dict>            <key>ssl.google-analytics.com</key>            <dict>                <key>NSThirdPartyExceptionMinimumTLSVersion</key>                <string>TLSv1.2</string>                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>                <false/>                <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>                <true/>            </dict>        </dict>    </dict>

Additional note: although google makes use of this "experimental standard" (certificate transparency):https://en.wikipedia.org/wiki/Certificate_TransparencyIt seems to not make use of it in google analytics :-)
