Run script for universal framework on Xcode 10

Question

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

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

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

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

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

if [ -d "${SIMULATOR_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/" ]; then

                                                                      cp -f ${DEVICE_LIBRARY_PATH}/Modules/${FRAMEWORK_NAME}.swiftmodule/* "${FRAMEWORK}/Modules/${FRAMEWORK_NAME}.swiftmodule/" | echo

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

                                                                      rm -rf "$OUTPUT_DIR"

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

echo "project"
#open "${PROJECT_DIR}"
if [ "true" == ${ALREADYINVOKED:-false} ]
then
echo "RECURSION: Detected, stopping"
else
export ALREADYINVOKED="true"

UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-iosuniversal

# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"

# Step 1. Build Device and Simulator versions
echo "iphone"
xcodebuild -target "${TARGET_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos  BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
echo "iphonesim"
xcodebuild -target "${TARGET_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build

## Step 2. Copy the framework structure (from iphoneos build) to the universal folder
echo "universal"
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/"

# Step 3. Copy Swift modules from iphonesimulator build (if it exists) to the copied framework directory
echo "iphone simulator path"
SIMULATOR_SWIFT_MODULES_DIR="${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule/."
if [ -d "${SIMULATOR_SWIFT_MODULES_DIR}" ]; then
cp -R "${SIMULATOR_SWIFT_MODULES_DIR}" "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule"
fi

# Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
echo "lipo create"
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"

echo "end"
fi

First Generate the Separate build for both simulator and device while opening your Products folder you will Find the separate build for both And then use this Run script in your project

After Generating the Script you Find the Folder IOS-Universal in Same product Folder

For me Working fine.

Answer 2

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.
