It still isn't great, but this has (so far) always worked for me. try the above steps one more time (this time you should only have to close Visual Studio for Mac followed by manually starting the Simulator, waiting for it to start, and then quitting the Simulator and finally restarting Visual Studio for Mac).

If you still can't see the simulator devices to run on.

Now close the Simulator (from the Simulator menu).

Launch the Simulator manually (I have it in the Dock, so I just click it).

If you can't run a Xamarin App, Close Visual Studio for Mac.

either on the Mac itself or on another computer connected to the Mac (if any).

Close ALL copies of Visual Studio that are connected to the Mac.

So hare's something I found works that you might want to try. So, at first, I started clearing the cache with a 'xcrun simctl erase all' command from Terminal, and when I started Visual Studio for Mac I could run a Xamarin App, but launching the simulator took quite a bit of time. it ends up being simpler and quicker than anything else I have found. but you may just want to go down to the Addendum 2 (final?) and see if that works for you. You are welcome to read through all of this. 'The target name of simulated device could not be added because it's already cached'.

Minimum system version (in ist): 11.Looking at the Visual Studio for Mac logs, specifically the IDE log, I found this line.

Visual Studio For Mac, version 8.8.6 (Build 15).

Operating system: MacOS Big Sur, version 11.1.

Operating system: macOS Catalina 10.15.7Īlso I have uninstalled XCode and installed again version 12.3Īnd I've uninstalled Visual Studio for Mac and installed it again.īelow, there is information about versions:.

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?
