问题
I'm using the XCode 7 beta that Apple released during WWDC2015, and it looks like iOS8 simulators are not there in it.
I tried downloading them using the Xcode > Preferences > Downloads > Components, but it doesn't list the simulators.
I have Xcode 6.3.2 also on the mac, and iOS8 simulators are visible there. Any ideas how to make it appear in Xcode 7?

The release notes of Xcode 7 beta 1 state:
Simulator
• Xcode 7.0 beta does not support iOS 8.4 and earlier simulator runtimes. (20699475)

First, find the target file:
/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/system/host/liblaunch_sim.dylib
You need make backup liblaunch_sim.dylib (Just in case). Second, copied to destination (Remember to backup)
/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 7.1.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/host/liblaunch_sim.dylib
And If need it to: iOS 8.1.simruntime iOS 8.2.simruntime iOS 8.3.simruntime All done.
Hope it helps.
