In case you would like to read/check your Target Build Settings in runtime using code, here is the way:

1) Add a Run Script: 

cp ${PROJECT_FILE_PATH}/project.pbxproj ${CONFIGURATION_BUILD_DIR}/${EXECUTABLE_NAME}.app/BuildSetting.pbxproj

It will copy the Target Build Settings file into your Main Bundle (will be called BuildSetting.pbxproj).

2) You can now check the contents of that file at any time in code:

NSString *thePathString = [[NSBundle mainBundle] pathForResource:@"BuildSetting" ofType:@"pbxproj"];
NSDictionary *theDictionary = [NSDictionary dictionaryWithContentsOfFile:thePathString];
