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

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。

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

通过稍微修改pAky88答案中的运行脚本并在嵌入框架后执行，这个问题为我解决了。还要确保取消“仅在安装时运行脚本”的复选框。

/usr/local/bin/carthage copy-frameworks

#!/usr/bin/env bash

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"

if [ ! -f "${FRAMEWORK_EXECUTABLE_PATH}" ]; then
continue
fi

if xcrun lipo -info "${FRAMEWORK_EXECUTABLE_PATH}" | grep --silent "Non-fat"; then
echo "Framework non-fat, skipping: $FRAMEWORK_EXECUTABLE_NAME"
continue
fi

echo "Thinning framework $FRAMEWORK_EXECUTABLE_NAME"

EXTRACTED_ARCHS=()

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

echo "Merging extracted architectures: ${ARCHS}"
xcrun lipo -o "$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

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
