Re: Does Xcode 2.2 change a 2.1 project file?

I recently upgraded my Xcode installation to version 2.2 from version

2.1 and noticed my project file remained unchanged.  I know this

because a `svn status` didn't include any project files.  This makes

me think I need to "upgrade" my project file somehow, but I don't

know if this is possible (or even necessary).



So my question is:  Does Xcode 2.2 change a 2.1 project file?


Yes and no.

The 'no' part is that Xcode 2.1 and 2.2 have the same project file format and layout, and Xcode 2.2 can open a 2.1 project without changes.

The 'yes' part is that there were bugs in the project file logic in Xcode 2.1 that are fixed in Xcode 2.2.  2.1 could write out a project file that could not be read in again.  This is fixed in Xcode 2.2, but necessitates changes in such projects; that is, merely opening the project in 2.2 will write to it and make changes in it.  In most cases these changes are OK on version 2.1.

There are some changes in 2.2 that are incompatible with 2.1, so that if you use these enhancements in your 2.2 project, it can no longer be opened or built with 2.1.  The main ones are noted in the Release Notes (under Xcode's Help menu).
