Auto-Increment Build Number for Multiple Targets in Xcode

Question

I have a "Free" and "Paid" version of my app, and I want to auto-increment both of the build numbers simultaneously, because sometimes I test with the "Free" version and sometimes I test with the "Paid" version depending on what I am doing. These are essentially the same codebase, I just have two targets with a preprocessor directive defined with the "Paid" version to unlock certain things.

I am using the code in this question: Version vs build in XCode

#!/bin/bash    
buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
buildNumber=$(($buildNumber + 1))
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

I think I just need to add two more lines specifying the path to the other $INFOPLIST_FILE along the lines of:

 "Print CFBundleVersion" "NEW_PATH/$INFOPLIST_FILE"

and increment it, but how do I get the path to one target's Plist when I am building the other?

An update for the latest Xcode, first change "Versioning System" to "Apple Generic" in "Build Settings" tab for all of your targets.

And add this line in "Run Script" of "Build Phases" tab for all of your targets:

agvtool next-version -all

agvtool will do the increment job for you!
