error: Building for iOS Simulator, but the linked and embedded framework 'App.framework' was built for iOS. (in target 'Runner' from project 'Runner')

Could not build the application for the simulator.
Error launching application on iPhone 11.

Condition

Xcode >= 11.4

Quick Solved

rm -rf ios/Flutter/App.framework

Run this command and run project again.

Official Solved

https://flutter.dev/docs/development/ios-project-migration

1. From the Flutter app directory, open ios/Runner.xcworkspace in Xcode.

2. In the Navigator pane, locate the Flutter group and remove App.framework and Flutter.framework.
3. In the Runner target build settings Build Phases > Link Binary With Libraries confirm App.framework and Flutter.framework are no longer present. Also confirm in Build Phases > Embed Frameworks.

4. Change the Runner target build settings Build Phases > Thin Binary script as follows:

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin

5. In the Runner target Build Settings > Other Linker Flags

(OTHER_LDFLAGS) add $(inherited) -framework Flutter

Hope it helps!
