XCode 4.3.2不会附加到调试器

我终于升级到Lion(从SL& Xcode 4.2).我现在正在跑步:

I finally upgraded to Lion (from SL & Xcode 4.2). I am now running:

• 当前的Lion 10.7.3
• 当前的Xcode 4.3.2
• 已安装当前模拟器5.1、5.0和4.3.

我已经远离当前的生产应用程序，并创建了一个简单的单视图通用hello world应用程序，以尝试使某种形式的模拟器调试工作.

I've backed way off from my current production apps, and created a simple single view universal hello world app, to try to get some form of simulator debugging working.

使用新的简单应用程序，我仍然可以在设备上进行调试，但不能在已安装的任何模拟器上进行调试.它会启动模拟器，最终安装被测试的应用程序，但永远不会附加到该应用程序上，并且该应用程序永远不会通过启动映像进行进度. (请注意，我可以从模拟器中启动该应用程序...因此，它确实可以正确构建和安装，尽管花费的时间比我使用SL& 4.2时要长一些)

With my new simple app, I CAN still debug on device, but NOT on any simulator I have installed. It launches the simulator, eventually installs the app under test, but never attaches to it, and the app never progresses pass the launch image. (One note, I can launch the app from the simulator... so, it did get built and installed correctly, although took a bit longer than I was used to with SL & 4.2)

Xcode只是坐在那里等待连接.令人担忧的是，我根本无法停止此操作(停止按钮，尝试关闭项目，停止任务)，必须强制退出Xcode.

Xcode just sits there waiting to connect. The worrisome part is that I can't stop this (stop button, try to close the project, stopping the task) at all, and must force-quit Xcode.

有人知道发生了什么吗?任何帮助将不胜感激！

Does anyone have any idea what is going on? Any help would be so greatly appreciated!!
