title: How to make Xcode Run Script x86_64 compatible
body: <p>Hello hello community!</p>
  
  <p>So here is my issue, welll not really an issue but the following Run Script compiles my static library and it works great! my only issue is that it doesnt compile it for the simulator and i get a x86_64 error. I know that i could just edit this code to make it compatible can someone tell me what i need to do??</p>
  
  <pre><code># define output folder environment variable
  UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
  
  # Step 1. Build Device and Simulator versions
  xcodebuild -target ${PROJECT_NAME} ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos  BUILD_DIR="${BUILD_DIR}"
  BUILD_ROOT="${BUILD_ROOT}" xcodebuild -target ${PROJECT_NAME} -configuration      ${CONFIGURATION} -sdk iphonesimulator -arch i386 BUILD_DIR="${BUILD_DIR}"      BUILD_ROOT="${BUILD_ROOT}"
  
  # make sure the output directory exists
  mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
  
  # Step 2. Create universal binary file using lipo
  lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a"     "${BUILD_DIR}/${CONFIGURATION}-iphoneos/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/lib${PROJECT_NAME}.a"
  
  # Last touch. copy the header files. Just for convenience
  cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/include" "${UNIVERSAL_OUTPUTFOLDER}"
  </code></pre>
