我最近已升级到xcode 10.2，但遇到一个奇怪的错误. 每当我尝试启动我的应用程序时，都会出现以下错误-等待60.00秒后尝试启动模拟器超时.

I have recently upgraded to xcode 10.2 and I am having a strange error. Whenever I try to launch my app I'm getting following error - Timed out trying to boot simulator after waiting 60.00s.

我什至尝试进行全新安装，但没有运气，我总是遇到相同的错误.

I have even tried do a fresh install but no luck I am always getting the same error.

有人知道我该如何解决吗?

Does anyone knows how can I fix this ?

推荐答案

我不确定为什么用这种方法修复了它. 我所做的是我在终端$ xcrun simctl erase all中运行了此命令. 之后，我什至从xcode再次运行我的项目，甚至没有下载任何东西，它就起作用了.

I'm not sure why it's fixed this way. What I did is I ran this command in terminal $ xcrun simctl erase all. After this I run my project again from xcode without even downloading anything and it worked.
