Auto-increment build number script for Xcode

increment_build_number.sh

TARGET="$PROJECT_DIR/project/Info.plist"
echo $TARGET
if [ ! -f "$TARGET" ]; then
   echo "missing file $TARGET"
   exit 1;
fi

# the perl regex splits out the last part of a build number (ie: 1.1.1) and increments it by one
# if you have a build number that is more than 3 components, add a '\.\d+' into the first part of the regex.

NEW_VERSION=`/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$TARGET" | /usr/bin/perl -pe 's/(\d+\.\d+\.)(\d+)/$1.($2+1)/eg'`
echo $NEW_VERSION;
/usr/libexec/PListBuddy -c "Set CFBundleVersion $NEW_VERSION" "$TARGET"

you should update the Target calculation to:

TARGET="$PROJECT_DIR/$EXECUTABLE_NAME/$EXECUTABLE_NAME-Info.plist"
