Xamarin iOS simulator issues - The device was not found

Question

I am trying to use the Xamarin iOS simulator but it fails on launch with a "The device {guid} was not found".

I have my environment settings like...

and when I run I see...

then...

researching the error, the recommendation is to explicitly set the XCode path which I have done, but I get the same error. Also, notice I am connected to our build Mac.

I have a coworker connected to the same Mac with the same computer and VS version I am on, and his iOS simulator works fine. I have uninstalled/reinstalled the simulator and restarted Visual Studio (2017RC).

I appreciate any pointers someone might have!

UPDATE

I reinstalled my Windows 10 OS thinking I had a corrupt install. Unfortunately on a clean machine with 2017RC, the simulator still fails in the same way as I described above.

Answer 1

In my case: UnCheck Remote Simulator to Windows

Answer 2

I am facing the same issue from last two days and solved this as well by removing the latest version of XCode 12.5. Download the previous version of code i.e 12.4 from apple site and install Move the downloaded xcode file in application and check on windows It works fine Latest version of XCode 12.5 is not stable

Answer 3

I confirm the issue is currently (May 2021) caused by Xcode 12.5 upgrade. After I downgraded back to Xcode 12.4, the simulators started to work again with no problem.

I tried to upgrade Visual Studio for Windows to latest version 16.9.4, did not help. I launched Visual Studio Installer to reinstall Xamarin, did not help either.

Only when I removed Xcode 12.5 (using this shell script https://onexlab-io.medium.com/uninstall-xcode-from-macos-eca1b69dc836) and installed version 12.4 (from XIP archive from here How to download Xcode DMG or XIP file?) it started to work.
