Like others, with the iOS 9.0 update, my Xamarin Studio will no longer connect to the iOS simulator. The most successful advice I've found in other threads is to switch to the beta version of Studio and Xamarin.iOS. I've done this. Now running Studio 5.9.7 (build 12) and Xamarin.iOS 18.104.22.168, along with Xcode 7.0.1 (7A1001)... and I'm still experiencing the same issue. Switching to beta did enable me to deploy to my device, but Studio still doesn't find the simulator.
I need Studio to find the simulator. If there are other options I've missed while researching the solution for this, I would greatly appreciate anyone pointing me in the right direction.
