title: Xcode 4 not launching application?
body: <p>Today, after installing <a href="http://en.wikipedia.org/wiki/Xcode" rel="nofollow">Xcode</a> 4 with the 4.3 SDK, I attempted to launch my application. However, the application will build and the iOS Simulator will pop up, but I get a message in the window in Xcode that says "Attaching to YourApp" which stays there indefinitely. How can this problem be fixed?</p>
