Downloaded XCode 7 to play around with the "Demo Bots" example. Now I've switched back to doing actual production work with XCode 6, and I'm getting the error "The iOS 8.4 Simulator runtime is not available" every time I try to run an app in the iOS simulator. Obvously XCode 6 was working fine launching iOS apps in simulator before I downloaded and used XCode 7.
Why is this happening and how can I use two versions of xcode without breaking their simulators?
Also attempting to run any app makes XCode 6 become unresponsive and requires force quitting.
And I can't re-download the iOS 8.4 simulators within XCode 6.4, they aren't listed.
You can use/run two versions, but don't rename either - did you do that? What happens if you login to OS X as another user and try there?
I'm seeing this problem and I renamed my Xcode apps. Is this a known problem? What should I do to resolve it?
Two things to try if fresh re-installs don't work: Run the 2 different Xcode versions from 2 different (fresh) Mac User accounts. Install the 2 different Xcode version in 2 separate bootable OS X drive partitions, and boot from the partition containing the Xcode version you want to use.
Restarting fixed the problem for me.
