检测的源码在 validator.rb文件，终端执行

gem which cocoapods

/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.10.0/lib/cocoapods.rb

打开 lib 文件夹，找到 cocoapods/validator.rb 文件

修改如下代码：

when :ios
        # command += %w(CODE_SIGN_IDENTITY=- -sdk iphonesimulator)
        # command += Fourflusher::SimControl.new.destination(:oldest, 'iOS', deployment_target)
        command += %w(ARCHS=x86_64)
        xcconfig = consumer.pod_target_xcconfig
        if xcconfig
          archs = xcconfig['VALID_ARCHS']
          if archs && (archs.include? 'armv7') && !(archs.include? 'i386') && (archs.include? 'x86_64')
            # Prevent Xcodebuild from testing the non-existent i386 simulator if armv7 is specified without i386
            command += %w(ARCHS=x86_64)
          end
        end
