Simulator is not working with upgrading xcode 10?
提问by Aashish1aug
After updating the Xcode 9.4.1 to Xcode 10, no one simulator is working to build the iOS application. My iOS Application was building and running perfectly on Xcode 9.4.1
将 Xcode 9.4.1 更新到 Xcode 10 后，没有一个模拟器正在构建 iOS 应用程序。我的 iOS 应用程序在 Xcode 9.4.1 上构建并完美运行
I have multiple warnings like this:
我有多个这样的警告：
warning: The iOS Simulator deployment target is set to 7.0, but the range of supported deployment target versions for this platform is 8.0 to 12.0.
警告：iOS 模拟器部署目标设置为 7.0，但此平台支持的部署目标版本范围为 8.0 到 12.0。
ScreenShot for Xcode10 error :
Xcode10 错误的屏幕截图：
And showing Multiple command produced in logs.
并显示日志中生成的多个命令。
I have tried following approaches :
我尝试了以下方法：
Delete derived data
Restart xcode
Create simulator manually from Xcode>Device/Simulator
删除派生数据
重启xcode
从 Xcode>Device/Simulator 手动创建模拟器
Not one works for me. Please guide me.
没有一个适合我。请指导我。

The simple way is to come back to the legacy build system, it seems to be a problem of the new build system.
简单的方法是回到遗留的构建系统，这似乎是新构建系统的问题。
