iOS Simualtor runtimes older than iOS 7.0 will not work with Xcode 6. iOS Simulator runtimes older than iOS 7.1 will not work on OS X Yosemite.
Older versions of the iOS Simulator runtime cannot be made to work with Xcode 6 nor on OS X Yosemite without significant changes to those legacy runtimes.
You can still build your apps to support older iOS versions by setting an older deployment target, but you will not be able to test them on a simulated device running on OS X Yosemite. You can test on a physical device running iOS 6.1, or you can run Xcode 5.1.1 in OS X Mavericks to test your project in the older simulator.
