Is there any way to override build settings per person in Xcode? - xcode

Question

I'm working on an iPhone app which connects to several services via REST API.
There are some servers for each service(development, production, etc),
and I want to switch these servers to connect by compiler flags WITHOUT modifying foo.xcodeproj/project.pbxproj.
I'm in a team of 6 developers and each person wants to connect to different servers combination,
but it will be a mess if I include these configuration in project.pbxproj which is managed by git.
So I need to change compiler flags with a file which is not managed by git.
Ideally, I want local settings mechanism like in Django.
Is there any ways to do this with Xcode?
Thanks! Any advice is highly appreciated.

Having your compiler flags not under source control is a huge RED FLAG. How can you guarantee consistent building of your app. // End Soap Box
Answer
I would create a user defined build setting for the production and dev servers. And a run script to set the server to use in the application info.plist
Add build setting REST_Server
Add run script to update the info.plist
# ---------------------------- IMPORTANT ----------------------------
# You must set RESTServer to something like 'Set by build script' in the file
# file '<Project Name>-Info.plist' in the 'Supporting Files' group
# -------------------------------------------------------------------
#
# determin server based on user name
#
SERVER=${REST_Server}
# Only use developer servers for debug never for release
if [ "$CONFIGURATION" != "Debug" ] ; then
exit
fi
if [ "$USER" == "gdunham" ] ; then
SERVER="gld.nextbigthing.com"
fi
if [ "$USER" == "jashmun" ] ; then
SERVER="jda.nextbigthing.com"
fi
echo $SERVER
#
# Set the server info in plist file in the build product not the source tree
#
/usr/libexec/PlistBuddy -c "Set :RESTServer $SERVER" "${TARGET_BUILD_DIR}/${INFOPLIST_PATH}"
Add place holder to info.plist

You can use the build configuration (.xcconfig)files to create different combinations of servers. Here is good explanation for how to configure this for your project: How can I use .xcconfig files in Xcode 4?
Each user can have their own .xcconfig file(s) and you can add these .xcconfig files to .gitignore
