问题：The iOS Simulator deployment target is set to x.x, but the range of supported deployment target versions for this platform is 8.0 to 12.0. (in target 'xxx')

解决办法：

更新xcode默认最低版本发生变化需要手动修改

同样修改pod中的所有targets都重新手动设置一下，支持到的最低版本

并不是添加下面这个就能解决的

post_install do |installer|
  installer.pods_project.targets.each do |target|
 target.build_configurations.each do |config|
  if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < 8.0
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '8.0'
     end
   end
  end
end
