解决办法:TARGETS->Build Phases->点击加号选择New Run Script Phase->然后复制粘贴下面代码 ,然后勾选: run script only when installing , 然后就没有然后了

    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
