Sounds like you have the new hardware (which has xcode 12 bundled), you tried to run flutter run with a physical iOS 13.6.1 device plugged in and it's failing with Description: Failed to find newest available Simulator runtime for some reason? If you open ios/Runner.xcworkspace in Xcode, select your physical iOS 13 device in the drop down after the flutter run command and run it in Xcode what happens?

[a-siva]

Yes running from Xcode works, but on my other mac I can run it just using flutter run

If you look at the log

_Launching lib/main.dart on iPhone in debug mode...
Automatically signing iOS for device deployment using specified development team in Xcode project: A3HUGF6PH6_
or
_Launching lib/main.dart on iPhone in release mode...
Automatically signing iOS for device deployment using specified development team in Xcode project: A3HUGF6PH6_

it clearly states launching on the device and yet it is not clear why it is looking for a Simulator

adding this to the 1.22 milestone as we'll need it in that release when it is done.
