Issues adding outlets In storyboard project.

Hi, I am trying to add an outlet on a control on a standard page, everything seems fine on XCode and I can see the code added to the .h file However when I go back to Xamarin studio I cannot access the control in the controller class, I have checked the designer class and this does not seem to be getting updated.

I have version 4.0.12 (build 3) installed on a mac machine. Is there a way I can add outlets manually, if so how can this be done please.

Thanks
