问题1:
``
ERROR ITMS-90087: "Unsupported Architectures. The executable for FileDownloader.app/Frameworks/GCDWebServers.framework

解决方法：
GCDWebServers.framework这个SDK里面包含了x86_64, i386 架构，AppStore是不允许的，所有会在上传的时候报错，解决办法就是要这个SDK剔除掉x86_64, i386这两个架构
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

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

问题2:

ERROR ITMS-90534:

解决方法：不要使用测试版Xcode或者GM版Xcode，请从App store下载Xcode重新打包上传

问题3:

ERROR ITMS-90362: "Invalid Info.plist value

解决方法：我的App中有ShareExtension，在ShareExtension的info.plist中，添加MinimumOSVersion字段

问题4：

ERROR ITMS-4238: "Redundant Binary Upload. There already exists a binary upload with build version '1' for train '1.0'" at SoftwareAssets/PreReleaseSoftwareAsset

这个是因为提交了重复的版本，项目会有两个版本：一个是“Bundle version string, short”，这个是项目发布版本；另一个是“Bundle version”，这个是内部版本。不能够提交两个相同“Bundle version”的项目。所以，修改你的“Bundle version”后提交。如，1.0  -->  1.0.1 -->  1.0.2   -->  ...  -->1.0.1001。
