Check your scheme settings and make sure all empty settings are unchecked. After doing this restart Xcode and simulator.
检查您的方案设置并确保未选中所有空设置。执行此操作后重新启动 Xcode 和模拟器。
If it doesn't work try to restart the system.
如果它不起作用，请尝试重新启动系统。

Old post, same situation here. After nothing of scheme settings, reinstall, reboot etc helped, the only thing helped for me:
旧帖子，这里的情况相同。在没有任何方案设置、重新安装、重启等帮助之后，唯一对我有帮助的事情：
Create a simulator for iPhone5s and iOS 9.3 (instead of iOS 10.3). Then advice project to use iOS 9.3.
为 iPhone5s 和 iOS 9.3（而不是 iOS 10.3）创建一个模拟器。然后建议项目使用iOS 9.3。
Hope this helps some people.
