Xcode: Product name or codename for project file name(.xcodeproj)?
===

I'm now changing project file name of Xcode because my **product** name(app name) was changed.<br>
And I got some problem due to changing project file name.(*This is not the question for this time. I also know I can change app name by `bundle display name` setting) <br>

I think I should have used codename(instead of product name) for project file name.<br>
If I did so, I don't need change project name forever.

Will I have any troubles if I use codename for Xcode project file?<br>
(for example, will apple reject the app?)

Which is commonly used for project file, product name or codename?<br>
How about your project file?


For example, code name of Windows Vista is `Longhorn`.<br>
I guess project file name of Windows Vista was not vista but Longhorn.
