How can I run the iOS 7.1 Simulator in Xcode 7.0 beta 2?

I have installed latest Xcode 7 beta 2 version, when I am trying to run the application in iOS 7.1 Simulator its giving this error message:

The iOS 7.1 simulator runtime is not available.

Unable to open liblaunch_sim.dylib. Try reinstalling Xcode or the simulator runtime.

Could you please let me know how to resolve this error?

Solution 1:

Took a lot of browsing but I finally found a solution that worked for me (tried Gend's answer but didn't work). Execute the following lines:

sudo mv "/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 7.1.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/host/liblaunch_sim.dylib"{,.bak}

sudo ln -sf "/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/system/host/liblaunch_sim.dylib" "/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 7.1.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/host/liblaunch_sim.dylib"

Solution 2:

You can't (At least in an Official way).

Taken from Xcode Beta 2 Documentation (Page 7).

Hope it helps.

EDIT SEPT - 2015:

Thanks Cœur for the info, now you can use previous versions of ios simulator.
