问题
I have a weird issue... I'm unable to find the simulator as a device in order to test my application. Anyone have any idea how to fix it? In a new project, it is available though.

Regards, EZFrag

Here's what happened to me ... when I updated to the latest version of XCode (4.3.2) I didn't bother to uninstall the previous version. I mistakenly opened my iOS 5.1 targeted project in the older version of XCode that does not know about 5.1 and as a result the simulator was not available. So i would check for the following:
- See which version of XCode you're currently running
- Try checking your iOS Deployment Target ... (Targets -> Deployment). If iOS 5.1 is selected change it to iOS 5.0 (the simulator will show up immediately)

In additional to G.Bickham's answer, please make sure the iOS Simulator is downloaded.
To verify the download status, go to Xcode's Preferences > Downloads > Components > iOS Simulator
