This will also occur when you don't have the simulator actually installed within XCode. I recently upgraded to XCode 7.1 and didn't install all simulators and received this same error.

• Go to Preferences -> Downloads
• Verify you have a checkmark next to the desired Simulator you are trying to run within XCode.
• If no checkmark, then install the simulator of choice. 8.1, 8.2, 8.3, 8.4
