使用下面的步骤从框架中删除[x86_64, i386]。[x86_64, i386]用于模拟器。

打开终端 打开你的项目拖动路径各自的框架到终端 例如:cd /Users/MAC/Desktop/MyProject/Alamofire.framework 在下面的命令中设置你的框架名称并运行

lipo -remove i386 Alamofire -o Alamofire && lipo -remove x86_64 Alamofire -o Alamofire

现在再次打开您的项目，清洁，构建和运行，并创建存档…

感谢以上所有的答案。下面是一个在swift 4.2和5中工作的脚本。将Your_Framework_Name字符串替换为框架的原始名称。

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
FRAMEWORK_NAME="Your_Framework_Name.framework"
# Check if Framework is present.
FRAMEWORK_LOCATION=$(find "$APP_PATH" -name "$FRAMEWORK_NAME" -type d)
if [ -z $FRAMEWORK_LOCATION ]; then
echo "Couldn't find Your_Framework_Name.framework in $APP_PATH. Make sure 'Embed Frameworks' build phase is listed before the 'Strip Unused Architectures' build phase."
exit 1
fi
# This script strips unused architectures
find "$APP_PATH" -name "$FRAMEWORK_NAME" -type d | while read -r FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(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

我从构建设置-有效架构-发布中删除了i386和x64_86架构，一切都工作得很好。

现在唯一的问题是您不能为了测试目的在模拟器上运行RELEASE版本。但是，如果你想的话，你可以很容易地把它们加回来。

pAkY88给出的答案是有效的，但我在https://stackoverflow.com/a/35240555/5272316:中遇到了马里奥·古兹曼(Mario A Guzman)一样的问题，一旦我们切断了未使用的架构，我们就不能再运行脚本了，因为它试图删除不存在的切片，因为xcode不会每次都重新嵌入二进制。 想法是-只是删除i386和x86_64切片时构建存档，所以我修改了脚本:

echo "Target architectures: $ARCHS"

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

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"
echo $(lipo -info "$FRAMEWORK_EXECUTABLE_PATH")

FRAMEWORK_TMP_PATH="$FRAMEWORK_EXECUTABLE_PATH-tmp"

# remove simulator's archs if location is not simulator's directory
case "${TARGET_BUILD_DIR}" in
*"iphonesimulator")
    echo "No need to remove archs"
    ;;
*)
    if $(lipo "$FRAMEWORK_EXECUTABLE_PATH" -verify_arch "i386") ; then
    lipo -output "$FRAMEWORK_TMP_PATH" -remove "i386" "$FRAMEWORK_EXECUTABLE_PATH"
    echo "i386 architecture removed"
    rm "$FRAMEWORK_EXECUTABLE_PATH"
    mv "$FRAMEWORK_TMP_PATH" "$FRAMEWORK_EXECUTABLE_PATH"
    fi
    if $(lipo "$FRAMEWORK_EXECUTABLE_PATH" -verify_arch "x86_64") ; then
    lipo -output "$FRAMEWORK_TMP_PATH" -remove "x86_64" "$FRAMEWORK_EXECUTABLE_PATH"
    echo "x86_64 architecture removed"
    rm "$FRAMEWORK_EXECUTABLE_PATH"
    mv "$FRAMEWORK_TMP_PATH" "$FRAMEWORK_EXECUTABLE_PATH"
    fi
    ;;
esac

echo "Completed for executable $FRAMEWORK_EXECUTABLE_PATH"
echo $(lipo -info "$FRAMEWORK_EXECUTABLE_PATH")

done

如果不是为模拟器(这意味着目标文件夹不像“debug - iphonessimulator”)运行，这个脚本只是从胖二进制文件(如果它们存在的话)中删除i386和x86_64切片。

对不起，我不熟悉shell脚本，所以可能有人可以用更优雅的方式编写它。但它确实有效)

如果您正在使用Carthage，请确保您的嵌入框架构建步骤在Carthage复制框架之前

在一些不寻常的情况下(例如:Lottie-iOS框架):

你可以像往常一样在“链接库”中找到它。 然而，你还必须显式地在“嵌入框架”中添加它(即使这看起来毫无意义，因为当你只在“嵌入框架”中添加它时，它会完美地工作)， 然后把它放到复制框架中 确保copy-frameworks在“Embed Frameworks”后面

此错误(ITMS-90240)也可能由静态(.a)库引起。这里有一个脚本来剥离多余的架构。在Xcode中将此添加到目标> BuildPhases >单击+并选择运行脚本。然后将其粘贴到脚本框中。

该脚本搜索.a文件，检查它是否包含有问题的体系结构，如果确实包含，则生成一个不包含该体系结构的新.a文件。

macOS:

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
STRIPARCHS="armv7 armv7s arm64"
for t in $STRIPARCHS
do

if find "$APP_PATH" -name '*.a' -exec lipo -info {} \; | grep $t ; then
    find "$APP_PATH" -name '*.a' -exec lipo -remove $t {} -output {}2 \; -exec rm {} \; -exec mv {}2 {} \; ;
fi

done

exit 0

对于iOS:

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
STRIPARCHS="x86_64 i386"
for t in $STRIPARCHS
do

if find "$APP_PATH" -name '*.a' -exec lipo -info {} \; | grep $t ; then
    find "$APP_PATH" -name '*.a' -exec lipo -remove $t {} -output {}2 \; -exec rm {} \; -exec mv {}2 {} \; ;
fi

done

exit 0
