Unable to install app in simulator xcode 9 beta
提问by Akshay Sunderwani
I downloaded Xcode 9 beta recently, and when I tried to run my app in the simulator it is not getting installed. I am getting this error in my Xcode every time I try to run the app.
我最近下载了 Xcode 9 beta，当我尝试在模拟器中运行我的应用程序时，它没有被安装。每次尝试运行该应用程序时，我的 Xcode 都会出现此错误。
Any help provided will be appreciated. Thanks in advance.
提供的任何帮助将不胜感激。提前致谢。
P.S: Application used to work in Xcode 8.3.3
PS：应用程序曾经在 Xcode 8.3.3 中工作

Unfortunately, the error message doesn't explain whythe 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:
不幸的是，该错误信息并不能解释为什么在安装失败。您可以查看 ~/Library/Logs/CoreSimulator/CoreSimulator.log 以查看错误消息的其余部分是否包含更多信息。如果没有，您应该查看 SIM 设备的系统日志：
sudo xcode-select -s /Applications/Xcode-beta.app # if you haven't already
xcrun simctl spawn booted log show
You can use --predicateto filter that down a bit.
你可以用它--predicate来过滤一下。

Late answer but might be that can be useful for others. I just get a project with existing watch-kit and custom keyboard code. After change the identifier i got the same error and i spend 1 day to find out why that happens.
迟到的答案，但可能对其他人有用。我刚刚得到一个带有现有手表套件和自定义键盘代码的项目。更改标识符后，我遇到了同样的错误，我花了 1 天时间找出发生这种情况的原因。
I checked everything of bundle id and all version. then i do global search in xcode with old identifier and i found that following.
我检查了 bundle id 和所有版本的所有内容。然后我使用旧标识符在 xcode 中进行全局搜索，我发现以下内容。
Here in both .plist file have old WKCompanionAppBundleIdentifierso after i update it with new manually application run again.
在这两个 .plist 文件中都有旧的WKCompanionAppBundleIdentifier所以在我用新的手动应用程序更新它之后再次运行。
IMPORTANT NOTE:
重要的提示：
IF YOU ARE JUST CHANGE IDENTIFIER FROM GENERAL TAB THAT DOES NOT MEAN IT UPDATE AT ALL. KINDLY CHECK WITH ALL POSSIBLE PLACES BY SEARCH AND REPLACE IT WITH NEW IDENTIFIER.
如果您只是从通用选项卡更改标识符，那并不意味着它根本没有更新。请通过搜索检查所有可能的位置并将其替换为新的标识符。

I had a similar issue when installing my App on the IOS simulator (with Xcode 9).
在 IOS 模拟器（使用 Xcode 9）上安装我的应用程序时，我遇到了类似的问题。
I found the issue (at least for my case), it was due to an unauthorized key (Privacy - Location When In Use Usage Description) in the info.plist of the Watch App.
我发现了这个问题（至少在我的情况下），这是由于 Watch 应用程序的 info.plist 中的未授权密钥（隐私 - 使用时的位置使用说明）。
I have moved this key to the info.plist of the WatchKit Extension and now the App installs again.
我已将此键移至 WatchKit 扩展的 info.plist，现在该应用程序再次安装。
I hope it will help others people having the same issue.
我希望它能帮助其他有同样问题的人。

This issue could be triggered by multiple things however if you take a look at the logs at ~/Library/Logs/CoreSimulator/CoreSimulator.logand it states an error that reads :
这个问题可能是由多种原因触发的，但是如果您查看日志~/Library/Logs/CoreSimulator/CoreSimulator.log并指出以下错误：
NSUnderlyingError=0x7fb51c271ee0 Could not hardlink copy /originPath to /destinationPath
NSUnderlyingError=0x7fb51c271ee0 无法将 /originPath 硬链接复制到 /destinationPath
it's possible that your Build number in your Project Target's settings is set to empty.
您的项目目标设置中的内部版本号可能设置为空。
Go to Project Target > Identity > Buildand set a Build number. You'll have to uninstall the the app in the simulator and re-install it before installing updated versions.
转到Project Target > Identity > Build并设置内部版本号。在安装更新版本之前，您必须卸载模拟器中的应用程序并重新安装它。
