iOS 合并SDK 报错 have the same architectures (arm64) and can't be in the same fat output file

问题一：真机模拟器库无法合并，报错：have the same architectures (arm64) and can't be in the same fat output file

lipo -create Release-iphoneos/xxxSDK.framework/xxxSDK Release-iphonesimulator/xxxSDK.framework/xxxSDK -output xxxSDK fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: Release-iphoneos/xxxSDK.framework/xxxSDK and Release-iphonesimulator/xxxSDK.framework/xxxSDK have the same architectures (arm64) and can't be in the same fat output file

XCode12之前：
编译模拟器静态库支持i386 x86_64两架构
编译真机静态库支持armv7 arm64两架构
使用lipo -create -output命令可以将两个库合并成一个支持模拟器和真机i386 x86_64 armv7 arm64四种架构的胖子库。

XCode12编译的模拟器静态库也支持了arm64，导致出现真机库和模拟器库不能合并的问题。

设置Build Setting --> Excluded Architectures --> Debug --> 添加上 arm64

设置Build Setting --> Excluded Architectures --> Release --> 添加上 arm64

出现的原因是XCode12 编译的模拟器库新增支持架构arm64。

将模拟器的arm64给排除出去即可。
