Insert Subversion revision number in Xcode

Question

I would like to insert the current Subversion revision number (as reported by svnversion) into my Xcode project. I managed to insert the revision number into the Info.plist in the $PROJECT_DIR, but this is not a good solution, since the file is versioned. I tried to insert the revision into the Info.plist in the build directory, but then I get an error during the code signing phase (this is an iPhone application).

Is there a simple way to get the revision number into the application using some build files, so that the changing revision does not change versioned files? I thought maybe I could create a temporary source file that would link with the others and provide a function to get the revision number. But I don’t know how to do that.

I am not much interested in other solutions, ie. the agvtool. All I want is the revision number available to the application, without too much magic.

I found this page when trying to do a similar thing for my iPhone app and thought it might be helpful to share the code I decided on. I was trying to have a base version number set in my Target Info (for example 0.9.5) but then append my SVN revision number at the end of it. I needed this stored in CFBundleVersion so that AdHoc users would be able to update via iTunes even if I didn't remember to rev the version number in my Target Info pane. That's why I couldn't use the "revision.h" method which otherwise worked beautifully. Here's the final code I settled on which I've placed as a Run Script phase just after the "Copy Bundle Resources" build phase:

BASEVERNUM=`/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "${INFOPLIST_FILE}" | sed 's/,/, /g'`
REV=`svnversion -n`
SVNDATE=`LC_ALL=C svn info | awk '/^Last Changed Date:/ {print $4,$5}'`
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $BASEVERNUM.$REV" "${TARGET_BUILD_DIR}"/${INFOPLIST_PATH}
/usr/libexec/PlistBuddy -c "Set :BuildDateString $SVNDATE" "${TARGET_BUILD_DIR}"/${INFOPLIST_PATH}

It should append the results of svnversion to the end of whatever is set in the base Info.plist as the version. This way you can have something like 0.9.5 in your info plist and still have the .189 revision number appended at the end, giving a final version number of 0.9.5.189

Hope this helps someone else!
