In my case (with VS Code) I just had to quit the simulator app in my dock and select the simulator again.

at the first run bellow command

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

and then

sudo xcodebuild -runFirstLaunch

after than run "flutter devices" now you see ios simulators if running

The major issue is with XCode. To quickly fix the issue, open project on XCode(make sure you choose the /ios path inside your flutter project.) and Open Preferences. On preferences dialog, go to Location and choose a command line tool from given option. Restart your IDE.

If you have multiple Xcode and don't have Xcode With default name "Xcode", this problem may occur. Try to rename one of xcode to "Xcode"

I have the same problem. Flutter doesn't see any simulators. Flutter required now Xcode 10.2 minimum. You can't run 10.2 on high sierra, therefore use flatter.

Which device do you use as a Simulator? From the docs:

Make sure your simulator is using a 64-bit device (iPhone 5s or later) by checking the settings in the simulator’s Hardware > Device menu.

Run flutter doctor. Are there any errors?
