Using a .embeddedframework (ios) in Unity - EntryPointNotFoundException

I'm trying to make a Unity plugin for the SDK I produce (so my customers can use my SDK in their apps).

I'm new to Unity, so I followed http://blog.zhengdong.me/2013/09/13/using-ios-android-libraries-unity3d and it compiles.

However, when trying to call the equivalent of humble_assistant_do_something, I get the error: EntryPointNotFoundException

When exporting the project (build and run -> xcode project), it gives a build error saying it can't find the header of my framework. So I'm not too sure of how to adapt the approach of the above article to an embedded framework (resource bundles etc).

Any ideas would be appreciated!

Thanks
