Flutter ios " Could not build the application for the simulator." - ios

I have an android app written with Flutter.
Now I am trying to ios version of it and I am getting errors. I tried to run empty flutter project, and it works successfully.
No errors with pod install
After I tried flutter run I am getting these errors.
My pod file on below.
How can I solve this problem?
Flutter run output:

Answer 1

Open lib/ios folder and delete
Podfile
Podfile.lock
Pods folder
Runner.xcworkspace
then run flutter build ios
After building ios, run open ios/Runner.xcworkspace/ and then run project in XCode for the first time, after that, everything would work fine.

Answer 2

Backup your project and try this command : flutter clean && \ rm ios/Podfile ios/Podfile.lock pubspec.lock && \ rm -rf ios/Pods ios/Runner.xcworkspace && \ flutter run

Answer 3

take a backup of project then delete ios folder and use command "flutter create ."
don't forget dot.

Answer 4

flutter clean
then go to
cd ios
then restart the IDE ..

Answer 5

Open pubspec.yaml,
click on pub_upgrade or type flutter pub upgrade
flutter clean ,
Open the lib/ios folder and delete the
Podfile.lock
and run
pod install
, after building the ios file, run the project of Xcode and everything will be fine.
