What I normally do is to create a test project in Xcode (you don't have to add anything to it). And then run that project from Xcode with the simulator. This will open the simulator. Now you should be able to see the simulator device in VSCode or Android Studio. So you can close the test project and Xcode and run your app from your IDE. This is so common I keep a test project in Xcode named "Blank for Simulator" so I can do this.
