Xcode 7 Beta 3 Simulator Performance

Hi Samm. This is a known issue in the release notes:

Known Issues

• The iOS 8.x Simulator may perform slowly on OS X El Capitan.

Hopefully it will be fixed soon.

So far the iOS 9 simulators have all been unusably slow for me under El Capitan... I hope a fix for this arrives in a beta. Some day.

Yes, the iOS 9 Simulator is slow, especially when running on a machine with a non-SSD hard drive.

I'm running on a Macbook Retina with SSD and I find it is slower than my 2009 iMac without an SSD
