Building for iOS, but the linked and embedded framework 'App.framework' was built for iOS Simulator.

解决
1.删除Flutter分组下的App.framework和Flutter.framework.

2.修改Build Phases > Thin Binary > Shell为如下代码

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

再次运行
