Perhaps <a href="https://stackoverflow.com/questions/5919959/iphone-simulator-folder-not-in-application-support">this</a> answer will help?

The simulator should be in this folder:

<pre><code>/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iOS Simulator.app
</code></pre>

Deleting the iOS Simulator folder of the iOS version in question in 

<pre><code>/Users/xxx/Library/Application Support/iPhone Simulator
</code></pre>

helps, but then you always have to repeat all the settings you made in the simulator (language, for example). Try to press the home button and then delete your app like you do it on a real iOS device. You should then be able to install it again.

This seems to be a <a href="https://stackoverflow.com/questions/18746093/xcode-5-ios-simulator-failed-to-install-application-every-time-i-switch-simu?rq=1">known issue</a>.

This is a version mismatch between your OS X version and your Xcode (iOS simulator)
and it seems that you have upgraded your OS X so Xcode needs to be upgraded as well, Check the versions that match with each other.
<h1>You need to upgrade your Xcode which will upgrade iOS simulator.</h1>
Good Luck,

I just updated my xcode to work with ios7. Now whenever I make a new app, even if its set to build for ios7, I get an error in the simulator when running. It says that the install failed, even if I just made the project and haven't coded anything into it yet. The simulator also shows a black screen. I have tried the reset content, and it didn't work. I saw something somewhere saying to delete the Iphone Simulator folder in application support, but no such folder seems to exist. What can I try to do?

Update--

With some additional research, I found that Iphone Simultor is in the Xcode.app now, but I don't know what to delete. There are many files under the iPhone Simulator Folder. If I delete the actual app, it just doesnt open. Any ideas?? I dont even get an iphone on the screen, just a black window...

Update 2:

Even when I just go to open developer tools -> iphone simulator 
it still gives me just a black screen....<img src="https://i.stack.imgur.com/veisY.png" alt="enter image description here">

Update 3

I just re-installed X-code, and all works now! Strange....I have no idea what happened...But I thought I would let y'all know for others who have similar issues.

我刚刚更新了我的xcode以使用ios7。现在，每当我做一个新的应用程序，即使它的设置为ios7，我得到一个错误在模拟器运行时。它说安装失败了，即使我只是做了这个项目，而且还没有将任何代码编码到其中。模拟器还显示了一个黑色屏幕。我尝试过重置内容，但没有成功。在应用程序支持中，我看到某个地方说要删除Iphone模拟器文件...
