I'm trying to add an iOS 9.0 iPhone 4s simulator to iOS 8. I've downloaded the iOS 9.0 runtime. But, when I try to create the simulator, I get a dialog box that says "Invalid runtime: com.apple.CoreSimulator.SimRuntime.iOS-9-0".
So, I tried to create the simulator on the command line using simctl. I get this
[palter@Herman ~/LearningTouch/iOS/trunk](28)$ xcrun simctl create "iPhone 4s" com.apple.CoreSimulator.SimDeviceType.iPhone-4s com.apple.CoreSimulator.SimRuntime.iOS-9-0
2016-09-29 14:54:53.694 simctl[40972:9235688] Unsupported FoundationXPCDataHeader version 28770.26988.
An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=159):
Invalid runtime: com.apple.CoreSimulator.SimRuntime.iOS-9-0
Any suggestions on what I should try next?
