I don’t think you can do this via straight config.xml
modification. At least, I didn’t see any mention of this in the docs: http://cordova.apache.org/docs/en/3.3.0/config_ref_index.md.html
I think you have to create a plugin, because they can insert plist entries: http://docs.phonegap.com/en/3.3.0/plugin_ref_spec.md.html#Plugin%20Specification
See the ‘config-file element’ section. Here’s a guess as to what the relevant section of the plugin.xml
will look like:
<platform name="ios">
<config-file target="*-Info.plist" parent="CFBundleURLTypes">
<array>
<dict>
<key>GDLibraryMode</key>
<string>GDEnterpriseSimulation</string>
</dict>
</array>
</config-file>
</platform>
Then you can install the plugin: cordova plugin add <your plugin name or file location>
