Unable to determine simulator device to boot. - Xcode

I just downloaded Xcode 6 & played with it a bit.

After switching back to previous version of Xcode and running in simulator, I keep getting this error.

Unable to determine simulator device to boot.

How do I add a simulator device to Xcode?

Open Xcode and click Menu > Xcode > Preferences > Select Components, and then choose the simulator version you want to download. When a simulator is opened from AppStudio, AppStudio Player automatically installs (if necessary) and opens in it.

Make sure you have only one iOS Simulator instance running in the Dock.
