I am running VS 2019 vs. 16.9.4. I have a Xamarin.Forms project and am trying to build & deploy to an iPhone simulator. I can connect to the mac and all seems ok on that end. When I try to start the app for the simulator I get a small window titled "iOS Simulator" which says "Connected", and then changes to "Waiting for device...", and then another small window pops up titled "Xamarin Simulator" which says "The device {GUID here} was not found."
I get this same series of messages regardless of which iPhone simulator I choose.
I have both XCode and Visual Studio 2019 for Mac running on the Mac.
What am I missing?
