不幸的是，错误消息并未解释安装失败的原因。您可以查看〜/ Library / Logs / CoreSimulator / CoreSimulator.log以查看其余的错误消息是否包含更多信息。如果没有，你应该查看sim设备的系统日志：

Unfortunately, the error message doesn’t explain why the install failed. You can take a look at ~/Library/Logs/CoreSimulator/CoreSimulator.log to see if the rest of the error message is there with more info. If not, you should check out the sim device’s system log:

sudo xcode-select -s /Applications/Xcode-beta.app # if you haven’t already
xcrun simctl spawn booted log show

你可以使用 - 谓词将其过滤掉。

You can use --predicate to filter that down a bit.
