Maybe it somehow connected to the issue I have.
Now XCode version is 12.2 and the error message related to the developer profile is gone. I uninstalled XCode 12.3 and Visual Studio and installed previous versions. Some time ago my XCode and Visual Studio were automatically updated to 12.3 and I start getting errors related to missing developer profile. Checked Solution options, Project settings. But when I work directly on MacBook, and run Visual Studio for Mac, there's only one (grayed) simulator available and I have no idea how to change it. When I pair my MacBook with PC, I have a list of iOS simulators available in Visual Studio 2019 ( on Windows). How can I change default iOS simulator on Visual Studio for Mac?
