Xcode 5.1 and Simulator In Use Error

Question

I've noticed that since upgrading to Xcode 5.1, the "Simulator In Use" error pops up randomly when trying to build/run. Sometimes nothing happens, and other times I get the error.

Even if there are no apps running, or the simulator is not running at all, I still encounter the error, which persists until I restart Xcode.

How can I fix this?

Fix this issue using below approach :

1. Quit the simulator and Xcode as well.

OR

1. Reset the content of Simulator. Goto to "iOS Simulator" menu -> "Reset contents and Settings.."
