I'm now changing project file name of Xcode because my product name(app name) was changed.
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)

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

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

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

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

There are no issues with naming your xcode project something different than the application. The display name is what matters to Apple and your users.

The second part of the question is not fit for Stack Overflow to answer, programmers.stackexchange might be a better fit.
