xcodebuild changed some of the values

test:

Add CUSTOM_BUNDLE_IDENTIFIER and CUSTOM_PRODUCT_NAME under the user defined section of build settings. Add a .xcconfig file to the project with CUSTOM_PRODUCT_NAME, and CUSTOM_BUNDLE_IDENTIFIER set to the nominal values. Set the product name to ${CUSTOM_PRODUCT_NAME} and bundle name to ${CUSTOM_BUNDLE_IDENTIFIER} in the info.plist. Set the Product Name to ${CUSTOM_PRODUCT_NAME} under build settings. When I want to change some of the values I create a new xcconfig file, and specify that xcconfig file using the -xcconfig param for xcodebuild. This allows you to change the settings on the fly.
