Problem launching an app in release mode Flutter on an iOS simulator

I can no longer launch my application in release mode on the simulator. When I type "flutter run --release" I get an error message "Release mode is not supported by iPhone 11.". Anyone else have the same problem?

I was having the very same error and mine was due to not having Developer mode enabled on my iPhone.

Solution as printed on the console: To use iPhone for development, enable Developer Mode in Settings → Privacy & Security.

Release mode do not supported emulator, I solve this problem by using real device. first connect your device using usb cable, then choose the real device:
