How to debug plugin source code in Xcode?

I am new to creating plug-ins for the Apple Mail Application, and I want to create Apple Mail plugin for OSX.

I have created a project under "Installer Plug-in" (Application Plug-in -> Installer Plug-in) in Xcode, but I can't debug that project like a simple iOS application.

Is it possible?

If it is possible then please help me.
