Firebase 不能与 iOS 模拟器一起运行。 Flutter

Question

as I said in the title I'm not able to run iOS simulator with Firecloud. If I only add Firebase_core package to pubspec.yaml all works fine, but when I add cloud_firestore: ^3.1.5 I got this error:

Ps With Android simulator all works fine.

Could not build the application for the simulator. Error launching application on iPhone 13.

Can anyone help me? I am stuck with this error since 2 weeks ago:S thanks to all.

Add this line in your pod file

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
      target.build_configurations.each do |config|
         if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < 9.0
           config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
         end
      end
  end
end

Solved. Thx Nazmul for the support: I did the follow:

In pod file just remove comments in target iOS version and changed it to 10. Then I had to delete the cache folder of cocoapods (~/Library/Caches/CocoaPods). Now all works “fine”. Over 500s vs the 20s of android to run the project but at least works.
