[iOS] Universal Framework Run Script와 오류 해결

단일 프레임워크를 Universal Framework로 만들때 쓰는 Run Script는 아래를 사용하고 있고,

#!/bin/sh
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal

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

# Step 1. Build Device and Simulator versions. This also include the full bitcode generation of framework
xcodebuild BITCODE_GENERATION_MODE=bitcode OTHER_CFLAGS="-fembed-bitcode" -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild BITCODE_GENERATION_MODE=bitcode OTHER_CFLAGS="-fembed-bitcode" -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphonesimulator BUILD_DIR="${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) to the copied framework directory
cp -R "${BUILD_DIR}/${CONFIGURATION}-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_DIR}/${CONFIGURATION}-iphonesimulator/${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}"

 

Cocoapod을 포함한 Workspace를 Universal Framework로 만들때에는 아래를 사용하고 있습니다.

(Workspace를 Universal Framework를 만들땐 Build가 아닌 Archive로 하고 있습니다.)

오류 케이스 1: Universal Framework로 만들고 나서 추가한 메인 프로젝트에서 bitcode 관련 에러가 나는 경우 

 

Universal Framework를 만들기 위해 생성한 Aggregate 타겟에서 Build Settings 에서 Apple Clang - Custom Compiler Flags 항목의

Other C Flags 값에 -fembed-bitcode를 추가한다.

 

 

오류 케이스 2: Universal Framework로 만들고 나서 추가한 메인 프로젝트에서 아카이브시 Code Signing 에러가 나는 경우

 

Universal Framework 를 사용한 메인 프로젝트의 타겟에 다음과 같은 Run Script를 추가한다.

# Type a script or drag a script file from your workspace to insert its path.
# skip if we run in debug
if [ "$CONFIGURATION" == "Debug" ]; then
echo "Skip frameworks cleaning in debug version"
exit 0
fi

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"

# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"

EXTRACTED_ARCHS=()

for ARCH in $ARCHS
do
echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"
lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
done

echo "Merging extracted architectures: ${ARCHS}"
lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
rm "${EXTRACTED_ARCHS[@]}"

echo "Replacing original executable with thinned version"
rm "$FRAMEWORK_EXECUTABLE_PATH"
mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"

done 

해당 Run Script는 불필요한 signing를 제거하여 아키이브시 오류가 나지 않도록 해준다.
