Run script for universal framework on Xcode 10

Question

I Xcode 9.x, I was using the below script which worked fine :

######################
# Options
######################

REVEAL_ARCHIVE_IN_FINDER=false

FRAMEWORK_NAME="${PROJECT_NAME}"

SIMULATOR_LIBRARY_PATH="${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${FRAMEWORK_NAME}.framework"

UNIVERSAL_LIBRARY_DIR="${BUILD_DIR}/${CONFIGURATION}-iphoneuniversal"

FRAMEWORK="${UNIVERSAL_LIBRARY_DIR}/${FRAMEWORK_NAME}.framework"


######################

xcodebuild -project "${PROJECT_FILE_PATH}" -target "${TARGET_NAME}"

######################

rm -rf "${UNIVERSAL_LIBRARY_DIR}"

mkdir "${UNIVERSAL_LIBRARY_DIR}"

mkdir "${FRAMEWORK}"


######################

######################

lipo "${SIMULATOR_LIBRARY_PATH}/${FRAMEWORK_NAME}" "${DEVICE_LIBRARY_PATH}/${FRAMEWORK_NAME}" -create -output "${FRAMEWORK}/${FRAMEWORK_NAME}" | echo

# For Swift framework, Swiftmodule needs to be copied in the universal framework
if [ -d "${SIMULATOR_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/" ]; then
cp -f ${SIMULATOR_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/* "${FRAMEWORK}/Modules/${FRAMEWORK_NAME}.swiftmodule/" | echo
                                                                      fi

                                                                      if [ -d "${DEVICE_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/" ]; then
                                                                      cp -f ${DEVICE_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/* "${FRAMEWORK}/Modules/${FRAMEWORK_NAME}.swiftmodule/" | echo
                                                                      fi

                                                                      ######################
                                                                      # On Release, copy the result to release directory
                                                                      ######################
                                                                      OUTPUT_DIR="${PROJECT_DIR}/Output/${FRAMEWORK_NAME}-${CONFIGURATION}-iphoneuniversal/"

                                                                      rm -rf "$OUTPUT_DIR"
                                                                      mkdir -p "$OUTPUT_DIR"

                                                                      cp -r "${FRAMEWORK}" "$OUTPUT_DIR"

                                                                      if [ ${REVEAL_ARCHIVE_IN_FINDER} = true ]; then
                                                                      open "${OUTPUT_DIR}/"
                                                                      fi

This didn't for Xcode 10. Later I saw that there was some modification required in the script. So I followed this answer to set the script. But after setting this script, when I try to build the Universal framework, Xcode hangs on Building script 1 of 1.
I have been trying to look for the right solution but failing each time.
What is the correct run script for a universal framework (covering all architectures) on Xcode 10 ?

Answer 1

Adding -UseModernBuildSystem=NO to xcodebuild command should work.

xcodebuild -workspace ${PROJECT_NAME}.xcworkspace -scheme ${PROJECT_NAME} -sdk iphonesimulator -configuration ${CONFIGURATION} -UseModernBuildSystem=NO clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphonesimulator 2>&1

xcodebuild -workspace ${PROJECT_NAME}.xcworkspace -scheme ${PROJECT_NAME} -sdk iphoneos -configuration ${CONFIGURATION} -UseModernBuildSystem=NO clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphoneos 2>&1

It should fix your problem.

This is the entire script I'm currently using and which successfully builds universal framework with Xcode 10. Link to gist

Currently, working to make use of latest build system to build universal framework. Shall update the answer soon.
