拆分framework

先把framework拷贝到两个文件夹下边，这里只需要armv7、arm64、x86_64。

mkdir iphoneos iphonesimulator
cp -R mysdk.framework iphoneos
cp -R mysdk.framework iphonesimulator

把iphoneos中的模拟器指令集删除，只保留armv7和arm64

lipo -remove i386 -remove x86_64 iphoneos/mysdk.framework/mysdk -o iphoneos/mysdk.framework/mysdk
#查看指令集
lipo -info iphoneos/mysdk.framework/mysdk

把iphonesimulator中的除模拟器之外的指令集删除，只保留x86_64

lipo -remove i386 -remove armv7 -remove arm64 iphonesimulator/mysdk.framework/mysdk -o iphonesimulator/mysdk.framework/mysdk
#查看指令集
lipo -info iphonesimulator/mysdk.framework/mysdk

合成xcframework

使用xcodebuild 进行合成

xcodebuild -create-xcframework -framework iphoneos/mysdk.framework -framework iphonesimulator/mysdk.framework -output "mysdk.xcframework"
