M1芯片的Mac无法在模拟器上运行项目building for iOS Simulator或could not find module for target..

真机上可运行，模拟器上不行，并出现以下错误：

in xx/xx/arm64, building for iOS Simulator, but linking in object file built for iOS, file 'xx/xx'

或

could not find module for target 'x86_64-apple-ios-simulator'
解决方案
1.在项目的project和target的Build Setting里，搜excluded architectures，然后双击它，会弹出一个弹框，点击加号（如下图）添加arm64

2、在pod文件里面添加如下代码
post_install do |installer|
installer.pods_project.build_configurations.each do |config|
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end
end

3.回终端pod install一下

注：之后如需在真机上运行则需把上面第一步和第二步恢复原状，然后pod install一下。

（在上架App Store前也需这样做）
