问题描述
今天，当我尝试在模拟器中运行我的应用程序时，它只是告诉我
Today, when I try to run my app in simulator, it simply tells me
Unable to run app in Simulator
An error was encountered while running
(Domain = NSPOSIXErrorDomain, Code = 22)
错误对话框如下所示:
我尝试了很多事情:
- 重新启动Xcode
- 重新启动模拟器
- 重新启动
- 重置模拟器的内容和设置
以上均不可行.我查看了日志，发现这些记录与该问题有关
None of above works. And I looked into log, I found these are those records has something to do with this issue

我还发现其他一些人在这里也遇到了同样的问题: https://gist.github.com/bdeshong/2dd90add09b7287a9a85
I also found some other people had the same issue here : https://gist.github.com/bdeshong/2dd90add09b7287a9a85
谷歌搜索后没有找到解决办法的运气.
No luck to find solution after Googling around.
这是我的环境信息
- OSX 10.9.5
- Xcode 6.0.1
- iOS模拟器8.0(550.1)
有什么想法吗?
推荐答案
我找到了根本原因，并且也找到了解决方案.我要做的第一件事是确保它与Xcode有关，而不是与项目本身有关的问题.我试图创建一个新项目，并且效果很好.因此，我认为这是由我的项目中的某些原因引起的.
I found the root causes, and I also found the solution. First thing I've done is to ensure this has something to do with Xcode rather than a problem relative to the project itself. I tried to create a new project, and it works perfectly fine. So I assume that is caused by something in my project.
我实际上在项目中添加了一个resources参考文件夹.所以我认为这个问题与它有关.但是，即使我从项目中删除了该文件夹，问题仍然存在.最后，事实证明resources文件夹可以存在
I actually added a resources reference folder to my project. So I think the problem has something to do with it. However, even I removed the folder from project, the problem is still there. In the end, it turns out, the resources folder could live in
- 内置应用程序文件夹
- 模拟器中的应用文件夹
由于Xcode可以简单地复制和覆盖目标App Bundle文件夹，因此resources文件夹可能仍存在于App bundle文件夹中.因此，删除resources文件夹后，您需要
Since Xcode may simply copy and overwrite target App bundle folder, so the resources folder may still there in the App bundle folder. So after removing the resources folder, you need to
- 确保构建已清理
- 确保模拟器中的应用已删除
由于该应用程序无法正确启动的原因，这是因为它显示resources实际上是.通过将名为resources的文件夹添加到分发包中，以某种方式破坏了常规结构.为了解决该问题，我将名称从resources更改为app_data或其他名称，都可以正常工作.
And for the reason the App cannot be launched correctly, that's because it appears resources is actually a reserved folder name in the bundle structure. By adding a folder named resources into the bundle, somehow ruined the normal structure. To solve the problem, I changed the name from resources to app_data, or whatever it is, that all work.
