Trying to get iOS 8 simulators in XCode 7. Prior to beta 3, that wasn\'t possible but in beta 3 release notes:
\"Xcode 7.0 beta now supports downloadable
sorry for the post, I don't have 50 reputation to comment. i am having this same issue. Any further progress? If I happen to come across a solution I will let you know. What have you tried?
--------- UPDATE -------
So I have found a work around.... if you are trying to get it to deploy to an iPhone.
If you still have the previous xCode file... you can navigate to Path: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
copy the simulators and SDKS you want over to the same location in Xcode-beta.app and paste... granted those downloads still won't download, but this will allow for the simulator to run on your iPhone.
I got this from Using the device simulator for iOS 8 with Xcode 7
and verified it works.
