What exact command produced that? Flutter is not supported in Release mode on the simulator.

flutter run. it can run in android stadio

flutter run defaults to release mode. You can target a real device with release, or the simulator with debug.

flutter run --debug

Duplicate of #11754.

Let's keep this open, I think we should detect the simulator is being targeted in release mode and short-circuit with a better error message.

failed to build

Do you have any plugins?
Does ios/Runner.xcworkspace successfully build in Xcode?

build in xcode with the problem,but i run flutter doctor can find flutter

ld: framework not found Flutter
clang: error: linker command failed with exit code 1 (use -v to see invocation)

1. What's the output of flutter doctor -v?
2. Do you have any plugins?
3. When you open in Xcode do you see Flutter.framework in your project?

You resolved the issue by reinstalling flutter again? Do you know what version you were on before?
I'm concerned that framework ever disappeared.

[Qiu-Jun]

Yes,it can run with iOS simulators ,when i reinstall flutter. I have forgotten the old version. The old version was installed about three or four months ago.

I have faced the same issue after re-installing XCode. To fix this I've just upgraded Flutter flutter upgrade and run pod install. Hope it'll help someone
