I'm building a basic Xamarin forms app. I've tried selecting many different iphone models as targets. The build goes without a hitch, but the app is not deployed to the simulator and it certainly isn't started. There are no error messages or warnings that I can find anywhere. The little status window at the top will flash something like "connecting to iphone simulator..." for a few milliseconds, and then nothing.
I have xcode 8.2.1 installed. This deploys to the simulator just fine. I verified Visual studio is correctly pointed to the xcode app location.
Building for android deploys and starts the app just fine.
