M4芯片的mac运行x86架构

前言

由于项目里部分三方库已经很久远，支持的模拟器版本不包arm64-simulator架构，导致直接在新电脑上运行模拟器直接启动不了

1、三方库信息如下：

lipo -info /Users/xx/xxx/xxx.a 
Architectures in the fat file: /Users/xx/xxx/xxx.a are: armv7 armv7s i386 x86_64 arm64 

2、如果直接使用会报错

Building for 'iOS-simulator', but linking in object file xxx.a[arm64][2](xxx.o)) built for 'iOS'

3、因为这个原因，导致三方库的xxx.podspec需要添加如下内容

Pod::Spec.new do |s|
  s.name             = "xxx"
  ....
  s.pod_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }
  s.user_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }
  ....
end

4、Xcode运行模拟器报错信息如下

提示信息：

    IDERunOperationFailingWorker = IDELaunchiPhoneSimulatorLauncher;
    SimCallingSelector = "launchApplicationWithID:options:pid:error:";
}

解决方案 安装Rosetta 2，让M系列芯片的电脑也可以按x86_64的方式运行

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

重启xcode运行运行即可
