Universal framework

유니버셜 프레임워크

  • 시뮬레이터는 x86기반, 실제 기기는 ARM CPU 기반이기 때문에 빌드가 다르다.
  • 그렇기 때문에 서드파티 프레임워크를 만들 때는 두 쪽 모두를 커버하는 빌드를 해야 한다.
  • Xcode 버전이 업그레이드 되고 M1 CPU를 지원하게 되면서 lipo때 오류가 나는 경우가 있어서 빌드에 주의해야 한다.

코드

  • Run Phase 또는 아카이브 시 등에 적용해 사용한다.
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-Universal
# Make sure the output directory existsmkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
 
# Next, work out if we’re in SIMULATOR or REAL DEVICE
xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
 
# Step 2. Copy the framework structure (from iphoneos build) to the universal folder
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
BUILD_PRODUCTS="${SYMROOT}/../../../../Products"
cp -R "${BUILD_PRODUCTS}/Debug-iphonesimulator/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule/." "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule"
 
# Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_PRODUCTS}/Debug-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"
 
# Step 5. Convenience step to copy the framework to the project’s directory
cp -R "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework" "${PROJECT_DIR}"
 
# Step 6. Convenience step to open the project’s directory in Finder
open "${PROJECT_DIR}"
