iOS simulator: could not hardlink copy. Wrong path in my filesystem?
提问by Don
I am using Xcode Version 6.1 (6A1052d)
我正在使用 Xcode 版本 6.1 (6A1052d)
I am trying to launch an app on the simulator.
我正在尝试在模拟器上启动一个应用程序。
The first time it always works fine. If I want to launch a second time, I have an error (see log below). Then in iOS simulator I "Reset Content and Settings" and I can launch again successfully.
第一次它总是工作正常。如果我想第二次启动，我有一个错误（见下面的日志）。然后在 iOS 模拟器中我“重置内容和设置”，我可以再次成功启动。
Given the error log, I think it must have something to do with a wrong path. The problem is I am bad with Mac filesystem and path linking, so your help would be much appreciated.
鉴于错误日志，我认为它一定与错误的路径有关。问题是我对 Mac 文件系统和路径链接很不满意，因此非常感谢您的帮助。

I have tried to identify more precisely the error thanks to the advice of Jeremy, in the system.log inside the folder of my virtual device. The system.log has a lot of entries around the time of the crash, so I might have missed something... Anyway I have found these potentials errors:

This is indeed triggered by the order of certain keys in your app's Info.plist file and what seems to be a bug in the iOS simulator's installdprocess. installdsometimes seems to be unable to read the CFBundleShortVersionStringand CFBundleVersionvalues. I've found that if RoboVM makes sure to always move those values first in the Info.plistit writes out we prevent the bug in installdfrom being triggered. We have now implemented this workaround in RoboVM (see issue #771) and it will be in the next nightly build (the 20150222 build) and in the next release.
这确实是由应用程序的 Info.plist 文件中某些键的顺序以及 iOS 模拟器installd进程中的错误触发的。installd有时似乎无法读取CFBundleShortVersionString和CFBundleVersion值。我发现，如果 RoboVM 确保始终首先在Info.plist它写出的值中移动这些值，我们就可以防止installd触发错误。我们现在已经在 RoboVM 中实现了这个解决方法（参见问题#771），它将在下一个夜间构建（20150222 构建）和下一个版本中。
Nightly builds of RoboVM can be downloaded from http://download.robovm.org. To install a nightly build of the Eclipse plugin you should use the update site
可以从http://download.robovm.org下载每晚构建的 RoboVM 。要安装 Eclipse 插件的夜间构建，您应该使用更新站点

I faced this error while leaving Buildfield blank using only Versionon Generaltab. The error has gone after setting a build value and reinstalling the app.
我在仅使用“常规”选项卡上的“版本”将“构建”字段留空时遇到了此错误。设置构建值并重新安装应用程序后，错误消失了。

I believe the issue is exacerbated if you change your app's Info.plist from one build to the next (such as revving CFBundleVersion or similar). If you do that, you should delete the app from the simulator between each launch (either via SpringBoard or using simctl) or just erase the sim device.
我相信如果您将应用程序的 Info.plist 从一个版本更改为下一个版本（例如 revving CFBundleVersion 或类似版本），问题会更加严重。如果你这样做，你应该在每次启动之间从模拟器中删除应用程序（通过 SpringBoard 或使用 simctl）或只是擦除 sim 设备。
This issue should be addressed in recent iOS Simulator 8.2 betas that are in Xcode 6.2 betas. I think it was addressed in either beta2 or beta3, but I can't recall for certain.
这个问题应该在最近的 iOS 模拟器 8.2 测试版中解决，这些测试版在 Xcode 6.2 测试版中。我认为它是在 beta2 或 beta3 中解决的，但我不记得了。

I encountered the same error using Xcode 8.2.1. Changing the order of items in the Info.plist did not help in my case. But it did lead me towards the solution. I had changed both CFBundleShortVersionString and CFBundleVersion from 3.0.0 to 3.0.1, BUT I HAD FORGOTTEN to also change to 3.0.1 in the localized and base InfoPlist.strings files. Doing that, fixed the problem.
我在使用 Xcode 8.2.1 时遇到了同样的错误。更改 Info.plist 中项目的顺序对我来说没有帮助。但它确实引导我走向解决方案。我已将 CFBundleShortVersionString 和 CFBundleVersion 从 3.0.0 更改为 3.0.1，但我忘记在本地化和基本 InfoPlist.strings 文件中也更改为 3.0.1。这样做，解决了问题。
回答by Naloiko Eugene
Find the InfoPlist.strings files. And check if the version of "CFBundleShortVersionString" = "1.1"; coincides with the version of your app in Info.plist
找到 InfoPlist.strings 文件。并检查“CFBundleShortVersionString”=“1.1”的版本；与您在 Info.plist 中的应用程序版本一致

Option-1: 1.Goto "General Setting" by clicking on the project name on left side bar. 2.Change the Bundle Identifier name to "com.release.ABC" (ABC may be any other name. It's better to replace ABC with your APP Name) 3. Now run it and Enjoy.
选项1： 1.点击左侧栏的项目名称，进入“常规设置”。2.将 Bundle Identifier 名称更改为“com.release.ABC”（ABC 可以是任何其他名称。最好将 ABC 替换为您的 APP 名称） 3. 现在运行它并享受。
Option-2: 1.Open Simulator. 2.Remove all apps installed by user. 3.Run your App and Enjoy. N.B: It has a demerit that every time you clean the simulator and then after, you will able to load your app.
选项 2： 1. 打开模拟器。2.删除用户安装的所有应用程序。3.运行您的应用程序并享受。注意：它有一个缺点，即每次清洁模拟器后，您都可以加载您的应用程序。

This fixed it for me:
这为我修复了它：
SIMULATOR_NAME="iPad Air 2"
# Erase a device's contents and settings
xcrun simctl erase "${SIMULATOR_NAME}"

I had this issue too for a long time. I tried most of these solutions. I'm sure they worked for some people, but not for me...
我也有这个问题很长时间了。我尝试了大多数这些解决方案。我敢肯定它们对某些人有效，但对我无效...
Then I noticed if you go to Project Settings -> Build Phases -> Embed Frameworksthere is a flag for Copy only when installing... I ticked it.
This problem went away.
然后我注意到如果你去Project Settings -> Build Phases -> Embed Frameworks那里只有在安装时复制的标志......我勾选了它。这个问题就迎刃而解了。

I experienced this issue in a multi-target project. After duplicating a target I forgot to change the "Product Bundle Identifier". Once I changed this parameter into a unique value (see tab "Build Settings"), the error disappeared.
我在多目标项目中遇到过这个问题。复制目标后，我忘记更改“产品包标识符”。一旦我将此参数更改为唯一值（请参阅“构建设置”选项卡），错误就消失了。
EDIT
编辑
After changing the "Product Bundle Identifier" you must erase all content and settings from the simulator and clean your build folder in Xcode (Cmd+Shift+K).
更改“产品包标识符”后，您必须清除模拟器中的所有内容和设置，并清理 Xcode 中的构建文件夹（Cmd+Shift+K）。

Select Project from Navigation window -> TARGET -> General -> Build or Version
Make sure both the field filled with some value.
确保两个字段都填充了一些值。
