I'm running VS 2017 on Windows 10 on PC and XCode 9.1 on Mac Mini w osx 10.13.1 (high sierra).
PRIOR to upgrading the OSX then XCode, I was able to SEE iOS simulators in the list in VS AND deploy to them on the Mac.
Since upgrading all on the Mac, I'm not seeing the iOS simulators showing in the list in VS.
Android app still runs just fine on similators.
I have checked for Xamarin Forms updates etc. all seems up to date.
Build is set to Debug, iPhoneSimulator and a simulator is running on the Mac.
VS connects to the build agent and all compiles, no prob.
Keep getting a message: Please select a valid device before running the application.
Can ANYONE PLEASE tell me what the prob is and any possible fix!
