The iOS applications of CRS-IUA output debug messages through NSLog. The DebugLog method is defined in the MobileCommerce-Prefix.pch file within the MobileCommerce Xcode project. Debug logging can be enabled for development by setting the ATG_DEBUG_MODE flag, but should be disabled in release builds. The flag is set for automated and debug build targets and not set for release builds, by default.

It can be changed in Xcode through the project settings found under the build settings tab. To change it, navigate to the build settings tab, and then set “Debug” under “Other C Flags” to be -DATG_DEBUG_MODE.
